Air Amplifier Pricing: How Can My Business Save Money?

Producing compressed air can be expensive and requires a lot of energy. Reducing the workload on the compressor is a smart way to save on energy costs and minimize daily wear and tear on the equipment. Eventually, this translates to lower maintenance costs, enhanced efficiency, and extended lifespan.

For example, if you have a piece of equipment in your plant that needs 120-130 psi while other equipment requires only 80 psi, you may be forced to maintain pressure at 120-130 psi throughout the entire plant just to run that one workstation. In addition to consuming more energy and paying more for it, you may also have greater losses due to leaks, which are magnified at high line pressures.

Reducing air pressure by 2 psi decreases the compressor horsepower by approximately 1%. If you reduce system pressure by 20 psi, you can decrease horsepower from the compressor by about 10%.

Similarly, lowering shop-wide pressure by 40 psi reduces the load on the compressor by 20%, translating into an annual savings of thousands of dollars in compressed air costs. Given these annual cost savings, you can recoup the initial capital expenditure of acquiring a MAXPRO® Air Amplifier Package in a matter of months. Here are the benefits you stand to gain with a MAXPRO® Air Amplifier Package:

  • Reduced energy costs: Lower shop pressure and higher specific machine pressure contribute to overall energy savings.
  • Enhanced production efficiency and product quality: Optimal pressure levels result in improved manufacturing processes and higher product standards.
  • Easy installation: The MAXPRO® Air Amplifier requires only shop air for operation, simplifying setup.
  • Automated operation: It automatically stalls at pressure and restarts upon air use, streamlining workflow.
  • Predictable maintenance: Simple maintenance procedures ensure consistent performance.
  • Cost-effective: Our air amplifiers require a lower investment compared to traditional electrical-driven compressors.
  • Enhanced portability: MAXPRO® Air Amplifiers feature a streamlined design with fewer components, enabling easy relocation.
  • Flexible installation: It is mountable on ceilings, walls, under benches, or within machines for versatility.
  • Noise control: The air amplifier operates at reasonable noise levels (around 80 dba) and remains silent in stall condition.

Hydrostatic Pressure Testing Equipment

What Is Hydrostatic Testing?

Hydrostatic testing, or a hydrotest, is the process of testing piping systems, pressure vessels, gas cylinders, fuel tanks, and boilers for leaks. The test involves filling the system with a test liquid, usually water, and raising the pressure to a desired level. Test operators then monitor the system for measurable or visible leaks during the specified test period.

Hydrotesting is an important process that helps analyze a pressurized system’s integrity. It plays a critical role in identifying faulty equipment and preventing potentially dangerous consequences for people and infrastructure in the surrounding environment. Learn more about hydrostatic testing, key considerations, and the hydrotesting equipment we offer at MAXPRO® Technologies.

When Is Hydrostatic Pressure Testing Required?

Hydrostatic pressure testing is a mandatory requirement to ensure compliance with the ASME B31 Pressure Piping Code and Department of Transportation (DOT) standards. Compliance with these regulations helps to ensure worker safety and avoid legal sanctions and liabilities.

Below is an overview of regulatory timelines for hydrostatic pressure testing for different systems.

Fire Extinguisher Systems

For dry chemical fire extinguishers, hydrostatic pressure testing should be done every 12 years. Carbon dioxide, pressurized water, and wet chemical fire extinguishers require more frequent testing—every five years.

Piping Systems

For pipeline systems, federal regulations require a hydrostatic test before any operation commences. Routine water pressure testing may be conducted once per year, or more frequently if leaks are suspected.

High-Pressure Cylinders

The DOT requires hydrostatic testing for cylinders every three, five, or 10 years depending on age, material type, cylinder content, and any special permits from the manufacturer.

Boilers and Heat Exchangers

Hydrostatic pressure testing for boilers and heat exchange units involves filling the system with water and pressurizing it to one and a half times the MAWP for a short period of time. If there are any leaks, the boiler cannot be used for routine use. This test ensures that the system can tolerate the high pressures and temperatures required during operation.

Considerations for Your Hydrostatic Pressure Testing Application

The following are important things to consider when selecting hydrostatic test equipment.


Hydrostatic testing involves two types of pressure: initial pressure and testing pressure. The initial pressure is the pressure after the test specimen is prefilled. The testing pressure is the required pressure the specimen is raised to for testing.

Testing Frequency

Your choice of hydrostatic test equipment should be able to handle the frequency of tests required, whether it’s daily, weekly, monthly, or yearly.

Flow Rate Required or Volume of the Specimen to Be Tested

You’ll need to know the flow rate required for the test or the volume of the specimen that requires testing. This will allow you to select properly sized testing equipment.


It’s also important to know how much time is available for the test to reach the desired pressure. Economic option: A smaller pump can be specified if time to pressurize is not critical.

Driver Type

Also decide on the type of driver preferred, such as engine, electric motor, power take-off or pneumatic.

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.

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…)

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.

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.

MTCAT-1.5 Coning and Threading Machine

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.
