Metal-to-metal seal

• Reliable and efficient radial cone-to-cone seal
• Quick connection and disconnection of sealing surfaces in the contact area
• Differentiated tightness of fit for the seal depending on the standard size

 

Results:

• Guaranteed tightness in difficult operating conditions taking place in case of combined loading, internal pressure, tension, compression, and bending.
• Opportunity of multiple assembly operations and of use as tubing.

Negative angle shoulder

• Increased shoulder thickness
• Protects connection from excessive torque and compression
• Accurately fixes mutual positions of seal and thread elements with the set values of tightness of fit
• Increases efficiency of the radial cone-to-cone seal, closes the inner contour of the pipe

Results:

• Assurance of the connection operability under significant torque and compression force.
• Stable operating parameters of the connection. The absence of disturbance of working fluid flow inside the pipe.

Buttress trapezoidal thread

• Has a free outlet to the pipe body.
• The tensile-weak section is maximally close to the section of the pipe.
• Load flank negative angle.
• Design clearance on the outer diameter of the thread.
• Large length of free pipe entry into the coupling.

 

Results:

• The connection failure load is equal to the pipe tensile failure load.
• The risk of threads coming out of contact under tension is eliminated.
• Exceptional resistance to abrasion.
• Ease of connection assembly.
