•Coupling design: Coupling critical cross sections are greater than those of the pipe body.
•A modified hook thread profile with -4°reverse angle on the load flank, 10 angles on the lead flank. It provides not only the connection with superior tension strengih, but also increases its resistance to compression.
2 3/8"-2 7/8" 8TPI
3 1/2"-4 1/2" 6TPI
5"-7 3/4”5 TPI
8 5/8" up 4 TPI
•A patented taper metal-to-metal seal system offers excellent gas-tight sealing, under even the most severe combined loads, such as bending and temperature loads.
•A reverse angle torque shoulder provides a positive torque stop which allows for accurate power-tight makeup and minimizes hoop stresses in the conneciion.
•Connecting 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 strength. ended by the reverse angle torque shoulder. The multi seal configuration ensures the connection to have high seal reliability.
•With the hook thread and 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 numerous benefits to using premium tubing over standard tubing, including:
- Increased durability and longevity.
- Superior resistance to corrosion, erosion, and other forms of wear and tear.
- Increased strength and reliability.
- Improved performance and efficiency.
