Premium Casing & Tubing RTN-60X
RTN-60X adopts an advanced thread geometry design to reduce thread galling: pitch change on coupling thread while pin thread maintain unchanged. This design concept avoids the high initial thread loads experieneed by conventional constant pitch threads.

•The contoured metal to metal seal provides a smooth continuous profile that improves sealing performance, reduces stress concentrations and provides for increased over-torque resistance.
•The inner wall of pipe body aligns with the coupling inner wall.
PERFORMANCE
•Connection strength: adopting optimized buttress thread, the connecting strength is high and can reach to the strength of pipe body.
•Seal property: the multi seal configuration with metal to metal seal and auxiliary torque shoulder ensure the connection to have high seal reliability. The design of main seal enables the joint to have the same capability of resisting the internal pressure as the pipe body.
•Composite bearing capacity: with the reverse torque internal shoulder, the joint has high capability to resist the compression, bend and over-torque load. Meanwhile when under the bend and complex load, it can still maintain the surface pressure on the shoulder.
•Inner flat design reduces the air and liquid turbulence in the pipe, so make the energy loss lower.
Premium tubing
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.
