Things You’ll Need
Screwdriver or rod
Tommy bar (supplied with the machine)
Setting tool (Supplied in the tool kit)
Coning Blade Installation
Two coning blades are required for each size and pressure, ¼” through ¾”, and must be identical.
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.
One coning blade and one ID deburring blade is used for coning 1½” OD 15,200 psig tubing.
Countersunk hole is on the top blade surface to accept a #8-32 flat head cap screw.
Check to make sure there are no chips in the blade pocket on the Tool Holder.
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
3. Open Head for Chaser Insertion
4. Inserting 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.

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

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:
Insert the tube into the tube holder until it can be seen at the top of the viewing window.
Place the flat end of the tube holder into a vice and tighten the collet nut to secure it in place.
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.
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.
Remove the coning tool by loosening the knurled nut.
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.
To start the first thread, install the die holder onto the end of the tube and firmly press down.
Add cutting oil into the die holder.
To obtain the appropriate amount of thread for a ¼” tube, turn the die holder approximately 12 times.
Every few turns, reverse the die holder to break off any chips.
The tube now has a cone and left-hand thread and can be removed from the die holder and the tube holder.
Install the gland and collar on the tube with 1 to 2 threads visible above the collar.
Lubricate the threads on the gland to prevent them from galling when the stainless parts are joined.
Install the tube into the fitting by hand tightening it.
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 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 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.
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.
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.
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 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.
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.
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 are designed for metering small flow rates with precise, repeatable control for both gases and liquids.

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:
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
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.
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.
