•Coupling connection type, the connection strength reaches to or over that of pipe body.
•Thread is improved buttress thread with high connecting efficiency, which is easy to process.
2 3/8"-2 7/8" 8 TPI
3 1/2"-4 1/2" 6 TPI
5" and over 5 TPI
•Main seal adopts taper to taper seal struciure with negative angle torque shoulder to enhanee its seal ability.
•The reverse torque shoulder improves the tonnection capacity of bearing combined load.
•The inner wall of pipe body aligns with the coupling inner wall.
When clearance is the limiting factor, ask for RTN-14AM-SC (Special Clearance).
•Connection strength: the connection with standard coupling can reach to the strength of pipe body.
•Seal property: the low angle taper to taper interference seal, further strengthened by the reverse angle torque shoulder. The multi seal configuration ensures the tonnection to have high seal reliability.
•With the reverse torque shoulder, the joint has high capability to resist the compression, bend and over-torque loads.
•Inner flat design reduces the gas and liquid turbulence in the pipe, so lower the energy loss.
Anti-galling design: it is permitted to makeup and breakout for several times.
There are various types of premium tubing available, each designed to suit specific applications and requirements. Some of the most common types include:
- Coiled tubing: used in oil and gas exploration, coiled tubing is a continuous length of pipe that is wound onto a spool.
- Seamless tubing: made of a single piece of metal, seamless tubing is used in high-pressure applications where leaks are not acceptable.
- Welded tubing: made by welding two pieces of metal together, welded tubing is used in applications where high strength and corrosion resistance are required.
