    Equipment Considerations for Hydrogen Applications

    Due to the inherent dangers of working with pressurized hydrogen, it is important to utilize high-pressure equipment that is reliable even in hazardous conditions. An understanding of the specific considerations for these types of applications helps ensure workplace safety and compliance with industry standards.


    Importance of Using the Right High-Pressure Equipment

    When compared to other types of fuel, hydrogen has a very wide flammability range. It is therefore vital that high-pressure equipment used in hydrogen applications does not have any weak points, as hydrogen may press against these points to create cracks or leakage. If the equipment cannot safely contain hydrogen, there are several hazards to be cognizant of.

    When pressurized hydrogen causes a crack in the piping system, it may lead to explosions. This is particularly dangerous because hydrogen requires such low amounts of energy to ignite. Hydrogen flames are difficult to see in daylight and do not produce smoke, making them challenging to identify without getting hazardously close.

    In addition to the risks surrounding hydrogen explosions and flames, other hazards to note include:

    • Hydrogen embrittlement. When hydrogen causes a material to lose ductility and become brittle.
    • Hydrogen permeation. A phenomenon wherein hydrogen ions penetrate thin diaphragms, leading to inaccurate measurements.
    • Hydrogen asphyxiation. A significant risk when hydrogen accumulates during a leak.


    Factors to Consider When Selecting High-Pressure Equipment

    When selecting the appropriate high-pressure valves, fittings, and tubing, there are many factors to consider:


    High Pressure Valves

    High pressure hydrogen valves must meet strict industry standards to ensure high performance even in harsh environments. Factors to consider when choosing a hydrogen gas valve include:

    • Temperature range. The valve must be able to operate well at a wide range of temperatures.
    • Regulating stem design. A regulating stem controls the flow of gas.
    • Seat material. Metal seats create a tighter shut-off, resulting in improved equipment longevity.
    • Valve body patterns. There is a range of patterns available depending on the needs of the application.
    • Sizes and ratings. Choosing the appropriate size ensures the valve will perform well under the required pressure.


    High Pressure Fittings

    Factors to consider when choosing high pressure fittings include:

    • Types of fittings. There are a range of fitting types to choose from, including adapters, couplings, and elbows.
    • Sizes and ratings. Depending on the size, fittings may have a pressure rating of standard, medium, high, or ultra high.
    • Quality control and industry standards. High pressure fittings should meet quality control standards such as those set by ASME.


    High Pressure Tubing

    When choosing high pressure tubing, it is important to consider both the diameter size and the pressure ratings. Tubing with a smaller diameter will generally withstand higher pressures than tubing with a larger diameter.

    When paired with the proper equipment, hydrogen has a vast array of applications, including:

    • Fuel cells
    • Power plant generator cooling
    • Chemical
    • Petroleum refining
    • Oil and gas
    • Hydrogenation of unsaturated fatty acids in vegetable oils
    • Hydrogen fueling stations
    • Glass manufacturing
    • Aerospace applications
    • Welding, annealing, and heat-treating metals
    • Pharmaceuticals
    • Fertilizer and ammonia production
    • Waterjet
    • High pressure food processing
    • Semiconductor manufacturing
    • Hydraulic power units

    Changing Coning Blades and Die Chasers on the Coning & Threading Machines

    Since 2011,  MAXPRO Technologies has been building  patented, easy-to-operate coning and threading machines.  Coned and threaded connections are a safe and reliable option for medium, high, and ultra-high pressure tubing.  Follow these instructions for changing the coning blades and die chasers. Click here to watch a video.  

    Things You’ll Need

    • Screwdriver or rod
    • Die chasers
    • Coning blades
    • Tommy bar (supplied with the machine)
    • Setting tool (Supplied in the tool kit)

    Coning Blade Installation 

    1.  Two coning blades are required for each size and pressure, ¼” through ¾”, and must be identical.  
    2.  One or two coning blades may be used for 1” OD tubing, 15,200 psi or 22,500 psi pressure rated tubing.  Two identical blade operation is standard for 1” OD tubing.  One blade may be used, especially if paired with optional 1” deburring blade for the ID of the tube.
    3.  One coning blade and one ID deburring blade is used for coning 1½” OD 15,200 psig tubing.
    4.  Countersunk hole is on the top blade surface to accept a #8-32 flat head cap screw.
    5.  Check to make sure there are no chips in the blade pocket on the Tool Holder.
    6.  Set each coning blade Part # side up  in the pocket and tighten firmly with 3/32” Allen wrench (provided).

     Thread Chaser Installation

    1. Access Die Head by sliding the carriage with the lever handle into the CONE position and lift the plastic shield.

    2. Trip head into open position

    Thread Chaser Installation

    3. Open Head for Chaser Insertion

    Chaser Access

    4. Inserting Chasers

    Inserting Die Chasers

    5. Closing the Die Head

    Coning Pitch Adjustment 

    1. With the Die Head in the closed, ready to thread position, check for the proper thread diameter by attempting to screw in a known good threaded tube, or, alternatively use a rod with an outside diameter equal to the minor thread diameter. If the test tube does not thread in, or threads in too tight or loose, adjusting ring binding (set) screw (5/32″ Allen wrench provided) on the adjusting ring must be loosened and the adjusting ring rotated with a 5/16″ diameter pin (provided) inserted into a hold on the adjusting ring.

    Loosen adjusting ring binding screw using provided hex key

    2. There are two marks on the adjusting ring. Rotating the ring towards “S” makes the thread diameter smaller (moving ring CCW as you’re facing the Die Head). Rotating the ring towards “L” makes the thread diameter larger (moving the ring CW as you’re facing the Die Head).

    By means of a pin inserted into the hold of the adjusting ring, turn until desired thread size is obtained.

    3. Check for proper thread diameter using matching size minor thread setup gauge (provided with complete tooling kits). Care should be taken not to force the chasers onto the setup gauge. Alternatively, a known good threaded tube can be screwed into the chasers. Ensure the tube does not thread in too tightly or loosely. Further minor adjustments necessary to obtain correct size settings are achieved by repeating steps 1 and 2.

    4. Re-tighten the adjusting ring binding (set) screw on the adjusting ring.

    5. A trial cone and thread should be made on a scrap piece of tubing (or excessively long tube) to confirm proper threading sizing. Threading a collar onto the tubing smoothly with little clearance will confirm an acceptable thread diameter.

    MAXPRO’s Data Logger

    Data Logger

    I have been in the oil and gas testing industry for over 24 years and found that one of the essential elements of testing is collecting data to create a snapshot of what occurred during the testing process. Testing is crucial when proving new designs and determining if component can withstand the elements before being put into service. These elements could include axial loading in tension/compression, applied bending, torsion, internal/external pressure, and elevated/sub-zero temperatures in tubular type products. Testing can introduce all these elements independently or in a combination of two or more simultaneously. The applications of simulated environments are pretty much endless. Proper equipment is vital to retrieve the best results to create a snapshot of everything that occurred during testing. (more…)

  5. Coning & Threading of High-Pressure Tubing

    Leave a Comment

    Coning & Threading of High-Pressure Tubing

    In medium- and high-pressure systems, coned and threaded tubing connections ensure safety and reliability.

    Tools Required

    • Bottle of cutting oil
    • Collet
    • Collet wrench
    • Coning blades (and spare)
    • Coning tool
    • Deburring tool
    • Threading tool 
    • Tube holder
    •  Optional Complete Coning and Threading Kit includes everything you need!

    How to Change the Coning Blades in the Coning Tool

    To begin, the coning blades need to be properly installed in the coning tool. Locate the part numbers etched on one side of the blade and place the blade in the coning tool with the numbers facing outward. Once the blade is correctly installed, tighten the set screws on either side of the tool to secure the blade in place


    Now that the tool has been prepped, the following steps will guide you through the coning and threading process:

    1. Insert the tube into the tube holder until it can be seen at the top of the viewing window.
    2. Place the flat end of the tube holder into a vice and tighten the collet nut to secure it in place.
    3. Cover the coning blades in cutting oil and install the coning tool onto the side of the tube holder opposite the tube by turning the knurled nut.
    4. Begin rapidly turning the handle of the coning tool while gradually turning the knurled nut to drive the blades into the cone on the end of the tube.
    5. Remove the coning tool by loosening the knurled nut.
    6. Loosen the collet nut and move the tube further into the tube holder and tighten it to allow you to hold the tube during the threading process.
    7. To start the first thread, install the die holder onto the end of the tube and firmly press down.
    8. Add cutting oil into the die holder.
    9. To obtain the appropriate amount of thread for a ¼” tube, turn the die holder approximately 12 times.
    10. Every few turns, reverse the die holder to break off any chips.
    11. The tube now has a cone and left-hand thread and can be removed from the die holder and the tube holder.
    12. Install the gland and collar on the tube with 1 to 2 threads visible above the collar.
    13. Lubricate the threads on the gland to prevent them from galling when the stainless parts are joined. 
    14. Install the tube into the fitting by hand tightening it.
    15. Place the assembly into the vice to torque the fitting using the appropriate sized torque wrench for your tubing.

  6. Main Types of High Pressure Valves & When to Use Them

    Leave a Comment

    Main Types of High Pressure Valves & When to Use Them

    High pressure valves are used to regulate the flow of liquids, gases and other media through tubing, pipes, tanks, and other containers. There are several valve types to choose from, including some that provide on/off control.  The type of high pressure valve you choose depends on the specific requirements of your application. Here, we will discuss the various types of valves and the key factors you should consider when selecting a valve for your application.  

    Features to Consider When Choosing a Valve 

    There are several things to consider when selecting a valve, including:


    • Media Type. When determining the best valve for your needs, it is important to consider your process.   For example, Is the fluid corrosive?  Are you using gas? 
    • Application. It’s crucial to select the correct valve sizing based on your application’s requirements. It’s also important to consider the environment where the valve will operate.   Understanding conditions such as temperature, flow rate, and pressure will help you determine the best valve option. 
    • Valve Function. Consider how you need the valve to function and whether it will be used for on/off control or flow control  in a system. It is also important to determine if the valve you require will be operated by hand or via an actuator for remote control applications.     
    • Actuation. Consider whether the valve should be “air to close–normally open” or “air to open–normally closed”.    

    Types of Valves

    At Maxpro, we carry several valve styles to suit many applications:  


    Air to Close, Normally Open Valve Actuators

    Air to close valves are held in the open position by the valve spring and require air pressure to move them into the closed position. Choose this valve if you want to vent pressure in the line if you were to lose power.


    Air to Open, Normally Closed Valve Actuators

    Air to open valves are held in the closed position by the valve spring and require air pressure to move them into the open position. Choose this valve to maintain pressure in the line during a power failure.  


    Ball Valves

    Maximator ball valves are capable of handling liquids and gases up to 21,000 psi at room temperature.  Ball valves have larger orifices resulting in increased flow.  Choose this valve for your control panel or other hydraulic system if flow is the most important factor.  

    Block and Bleed Valves

    Maximator block and bleed valves are compact and easy to use.  Block and bleed valves are two-stem manifold valves designed for blocking, bleeding and calibrating  pressure gauges and transmitters up to 22,500 psi @ room temperature. 


    Cryogenic Valves

    Maximator cryogenic needle valves are designed to work with  line temperatures to -423°F.    For example:  This valve can be used  on high pressure nitrogen injection trucks and skids to control the flow of nitrogen.  


    Electric Flow Control Valves

    Electric flow control valves use an electric control signal to meter small flow rates with repeatable and precise control for liquids and gases. These valves are for metering only and are not ideal for complete shutoff applications.  One example of an application would be simulating a down hole environment by pressurizing or venting a large volume vessel with a controlled pressure ramp rate.  


    High Pressure Adjustable Relief Valves

    Maxpro proportional pressure relief valves are designed to protect systems and components from over-pressure for both gas and liquid applications.  The unique poppet design allows for chatter free pressure release and excellent deadband pressure control.  


    High Pressure Check Valves

    High pressure check valves permit fluid flow in one direction only, thus preventing backflow in high pressure applications.


    High Pressure Needle Valves

    Maximator high pressure needle valves  provide on/off control of fluids and gases.  These  valves are used in conjunction with high pressure fittings and tubing to plumb systems to 101,000 psi.  


    High Pressure Pipe Valves

    Maximator pipe valves with metal to metal seats provide on/off control for fluids and gases and are rated up to 15,200 psi.  


    Manifold Blocks

     A manifold is a component used to simultaneously connect multiple parts into a system so all parts are exposed to the same circuit conditions (such as media or pressure).  A manifold is used in place of multiple connections between components.   For example:  A manifold can be used  to hydrostatically test multiple parts at the same time.


    Micro-Metering Valves

    Micro-metering valves are designed for metering small flow rates with precise, repeatable control for both gases and liquids.

  7. Introducing MTCAT-1.5: MAXPRO’s New Coning & Threading Machine

    Leave a Comment

    Because they are dependable, reusable and safe, coned and threaded connections are the industry standard for medium-, high-, and ultra-high-pressure systems. That’s why MAXPRO® Technologies is pleased to introduce the MTCAT-1.5, the only coning and threading machine available capable of handling up to 1-1/2 inch OD medium-pressure tubing.

    Advantages of Coned and Threaded Connections for Your Application:

    Maxpro Coning & Threading Machine

    • Dependable. If the user starts with high quality components and tooling from Maxpro Technologies, follows prescribed instructions for tube preparation, lubrication requirements and torque specifications, this metal-to-metal joint is recognized as a world standard for dependability.
    • Reusable. The coned and threaded connection utilizes a gland nut to grip a collar threaded onto the tubing. This arrangement creates an intentional high stress, metal-to-metal contact ring, employing slightly differing contact angles to affect the seal. Following proper assembly procedures, this seal can be remade many times without compromising the effectiveness.
    • Safe. The design of this type of seal minimizes the internal pressure loaded area to allow efficient use of materials, while assuring a suitable factor of safety. If a leak should occur, weep holes are provided to allow venting of the fitting to avoid unsafe pressure loading conditions.

    Industries that commonly benefit from coned and threaded connections include food processing, oil and gas, pressure testing, and waterjet cutting to name a few.

    MAXPRO’s MTCAT-1.5 and MTCAT Features:

    While coned and threaded connections are dependable, reusable, and safe, the coning and threading process can carry high labor costs. Manual coning and threading operators must be carefully trained in how to prepare and process the tube ends. MAXPRO coning and threading machines make it much easier and cost-efficient to cone and thread high-strength tubing. The original MTCAT and new MTCAT-1.5 Coning & Threading Machines integrate the following features:


    MAXPRO ‘s MTCAT and MTCAT-1.5 both offer a semi-automated design engineered for speed. They offer faster set-up and operation for better efficiency. The tube only needs to be fixtured once for both coning and threading operations, which eliminates extra set-up and downtime between the two processes. The die head automatically resets after threading, allowing for easy unloading and preparing for the next tube.

    Ease of Use

    Both the MTCAT and MTCAT-1.5 are designed for intuitive use. After completing either a brief training program or reviewing the comprehensive instruction manual provided with all machines, operators can produce quality components. One of the main control mechanisms of the MTCAT-1.5 and MTCAT is a simple selector knob that allows the operator to choose thread length automatically depending on the size of the tube.


    The MTCAT-1.5 and MTCAT are both available in right-hand and left-hand thread variations. Customers can choose whichever design suits their needs. MTCAT can cone and thread ¼” through 1” OD tubing and MTCAT-1.5 can cone and thread ¼” through 1-½” OD tubing

    Tool Quality

    Hardened blades made of high-quality, durable tool steel deliver precise results with a clean surface finish typically lasting over hundreds of tubes.


    The MTCAT-1.5 and MTCAT Coning and Threading Machines are fully enclosed with Plexiglass shields and other suitable machine guarding. This design minimizes pinch points and protects operators from metal chips and cutting oil.

    Mess Free

    Both MATCAT-1.5 and MTCAT Coning and Threading Machines provide excellent cutting oil delivery right through the rotating spindles accurately to the cutting blade area. No external gooseneck nozzles to mess with! They also provide for a two-fold filtering process for clean and easy removal of the strained chips with a convenient handle. A suction strainer further removes chips before pumping oil back to cutting action.

  8. How to Repair & Lubricate Spool Valves Used On L Series Liquid Pumps, DLE Series Gas Boosters, DLA & GPLV2 Air Amplifiers

    Leave a Comment

    Maximator® dry air spools (DAS) can be used for liquid pumps, gas boosters, and air amplifiers. They are suitable for dry air, nitrogen, and other severe operating conditions (e.g., air dew point below 0° F and ambient temperature below 0° F). The following article covers how to repair and lubricate the spool valve.

    Tools Needed:

    • Spool tool remover – Sold by Maxpro
    • Hammer or mallet
    • Pliers
    • Repair kit- Includes O-rings and a snap ring
    • Grease – We recommend Kluber Lube, Polylub GA 352 P High Temperature Grease. This grease has good long term adhesion and water resistance.

    Overview of the Spool Valve Repair & Lubrication Process

    1. Loosen four cap screws that hold the spool housing to the end cap to release any air trapped in the spool valve.
    2. Remove the snap ring from the spool valve housing.
    3. With a long screw driver or wooden dowel, from the ½” FNPT side of the housing, push out the spool plug and spool from the housing.
    4. Clean the spool and bore of the housing sleeve. Check the O-rings for wear and the spool sleeve for scratches. Replace if necessary.
    5. Put a light coat of grease on the O-rings and in the bore of the spool sleeve.
    6. Insert the spool into the spool sleeve, small side first, gently moving the spool from side to side with very little pressure on the end of the spool. DO NOT FORCE. The O-rings fit loosely on the spool and can be cut if they are forced in.

    The experts at MAXPRO can help your team identify the right valve for your application.

    High Pressure FittingsHigh-Pressure Fittings

    High-pressure valves and tubing must be used with fittings with the same pressure rating. Maximator high-pressure fittings have been engineered to provide reliable performance and maintain system integrity in hazardous working environments. The complete line of fittings includes:

    • Adapters. Available in male/male or male/female configurations, our adapters allow users to connect components of different sizes.
    • Anti-vibration collet/gland assemblies. Provides extended support and rotational grip for the tubing that is entering the connection fittings with the use of a secondary compressor-type fitting. In doing so, they shield the coned and threaded connection from excessive tube loading and vibration.
    • Couplings. Couplings can connect components of either similar or dissimilar sizes.
    • Elbows. Elbows add two common connections to a tubing line, also forming a right angle.
    • Tees. These T-shaped fittings add three common connections to a tubing line.
    • Crosses. Named for their cross shape, these parts fit four common connections to a tubing line.
    • Nipples. Nipples connect two common male connections to tubing.
    • Safety head assemblies. Safety head assemblies are used for overpressure protection

    What is a Hydraulic Intensifier?

    A hydraulic intensifier system is quite simple in principle, the system uses hydraulic power to increase the pressure of a liquid or gas. Pressure multiplication occurs because of the dissimilar areas between the hydraulic piston and the process media piston. The ratio of the area between the hydraulic piston and process media piston is known as the pressure ratio.

    (Ex: a 10in³ hydraulic piston pushing a 5in³ process media piston had a ratio of 1:2). A ratio of 1:2 can multiply the process media pressure by two times the hydraulic pressure.

    Single Stage Intensifier

    With a single stage intensifier both the left and right sides have the same ratio resulting in one pressure discharge from the intensifier for every stroke as shown in the picture.

    Two Stage Intensifier

    With a two-stage intensifier the left and right sides have different pressure ratios, this is also known as a multiple ratio intensifier. Multiple ratio intensifiers allow for a larger pressure multiplication than with a single stage. This style of intensifier only produces a pressure discharge every other stroke as shown in the picture.

    What’s New?

    Maxpro Technologies has recently designed a new generation of intensifiers to seamlessly integrate with modern and advancing technologies. Our intensifiers now have the option of using electronics and integration to bridge the gap of the mechanical and digital world.

    With our latest generation of intensifiers, we are now able to have real time monitoring and feedback of all machine parameters right at your fingertips. For example, the machine is constantly analyzing inlet pressure, outlet pressure, hydraulic flow rate and temperature, coolant flow rates and so much more.

    You might wonder why it is so important to continuously analyze all this data, after all our previous generation did not do this. The reason is simple, More Control – More Efficient – Endless Possibilities.

    More Control

    Our automated intensifiers with process monitoring have user programmable recipes to keep your process on point. Minimum and maximum process media pressures can be defined along with specific flow rates to dial in your process like never before.

    More Efficient

    In today’s world manufacturing is about being lean. Companies are constantly striving to increase productivity while simultaneously decreasing process waste. In the case of our intensifier, we were able to significantly reduce electrical waste. Running motors can be expensive especially under high load. Our control and monitoring system gives you on demand power when you need it and idles without load or powers down when not in use.

    Endless Possibilities

    No one knows your process better than you; this is why our system is programmed to be flexible. Recipes allow the user to have different process setups saved in the controller, all of which are continuously monitored to keep everything running safely.

    In modern times people are accustomed to being connected to their devices. Our latest intensifier is set up to be no different. Our controls system can remotely interface where an internet connection is available as well as receive email notifications of critical machine events. An auxiliary plug prewired to be integrated with other pieces of equipment is also included.

    Can You Benefit from an Intensifier?

    Hydraulic Intensifiers can be used any time the available liquids or gases are at pressures lower than what is required by the process. Intensifiers will take low pressure liquid or gas and boost them to a specific pressure and flow rate depending on the intensifier configuration and horsepower. Some common pumping media and applications are as follows.

    Common liquids

    • Carbon Dioxide
    • Water
    • Oil

    Common Gasses

    • Nitrogen
    • Carbon Dioxide
    • Hydrogen
    • Dry Air
    • Helium
    • Argon

    Industry Applications

    • Gas Foaming of Polystyrene
    • Gas Cylinder Filling
    • Supercritical CO2 Extraction & Cleaning
    • Gas Assisted Injection Molding
    • Gas Supply to Sintering Furnace
    • Burst Testing
    • Gas Tube Trailer & Cylinder Scavenging
    • Gas Vapor Reclaim from Cryogenic Storage
    • Supply Gas to Hot Isostatic Pressing (HIP)
    • Cold Isostatic Pressing (CIP) of powdered metals and ceramics
    • Hydrostatic pressure testing

    Engineered Solutions

    Maxpro Technologies offers three system levels;  manual, control and monitoring, and also control and monitoring with tubing.


    Manual systems are the simplest form of the hydraulic intensifier. These systems consist of the intensifier, hydraulic power unit and a motor starter with on/off control. This style of system must either be manually operated or integrated into other equipment due to the absence of process feedback. This is a great style of system for someone who wants to do all their own integration and controls or wants a budget system to operate manually.

    Control and Monitoring

    The control and monitoring system is a plug and play system recently designed to fill a rapidly increasing market demand. This style of Intensifier is a closed loop system meaning it constantly watches your upstream and downstream processes and makes decisions on how to operate based on that data. The advantage of this style of system is that it takes all the guess work out. The integrated recipe page allows you to set up custom process parameters that the system can safely operate within.

    Control and Monitoring with Tubing

    Systems that incorporate the addition of external plumbing are turnkey systems. These systems not only control the intensifier as described in the control and monitoring system, but they also control any upstream and downstream plumbing as specified by the customer. At Maxpro, our engineers and designers are dedicated to designing custom systems to your specifications.
