Description:
Structure:
1) Patent No.: ZL02257690.8
2) Coupling connection type: the connection strength reaches or exceeds that
of the pipe body
3) Thread: improved buttress thread with high connection strength, which is
easy to process
4) Main seal uses the box with spherical face to the pin with a cylindrical face
radial seal structure, which has good sealing properties
5) The -15° reverse torque shoulder improves the connection combined
load bearing capacity
6) The inner wall of the pipe body aligns with the coupling inner wall
7) Surface treatment:
a) Pin: no surface treatment
b) Box: phosphorized or copperized

Usage properties:
1) Connection strength: uses optimized buttress thread, the connecting
strength is high and can reach the strength of the pipe body
2) Sealing: the multi-seal configuration with the main cylindrical face to
spherical face seal and auxiliary torque shoulder ensures that the connection
has high seal reliability. The design of the main seal enables the joint to have
the same capability of resisting the internal pressure as the pipe body
3) With the reverse torque internal shoulder, the joint has high capability to
resist compression, bending and over-torque load. When under bend and
complex loads, it can still maintain the surface pressure on the shoulder
4) Inner flat design reduces the air and liquid turbulence in the pipe, and so
lowers the energy loss

Operating performance:
1) Easy to assemble: convenient to assemble correctly at the oil field with the
triangle mark and /or torque control
2) Galling resistant: capable of being assembled and disassembled many times
3) The tooth crest is parallel to the pipe axis, so it is easy to start to assemble
without thread deviation

Usage scope:
1) High pressure oil wells
2) High pressure gas wells
3) Deep and over-deep wells
4) High collapse wells
5) Hot well-drilling wells
6) Oriented wells and over-clint horizontal wells

Specifications:
1) Standards: API 5CT, Non-API standard
2) Sizes: OD 2 3/8"-13 3/8"
3) Grade: J55, K55, N80, L80, T95, P110

Packing: bundle or bulk
