1. TP-G2 HP premium connection

lt adopts the overall sealing structure to ensure that the joint strength canreach 100% of the pipe body strength under tension, compression, internal pressure, and external pressure load. The lSO13679 Grade 4 test has been complet-ed.

2. TP-ISF premium connection

It adopts the double sealing surface design to ensure excellent gas sealing performance of the joint under both internal and external pressure loads. The middle torque shoulder faces the top to control the screw and connection positioning and thus facilities on-site use in the oil field. Furthermore, the bipolar hook-type thread connection ensure that the joint connection efficiency can reach 70-80% of the yield strength of the pipe body.

3. MO-WS premium connection

MO-WS is a premium connection for integral semi-direct connected oil pipes, and features dual-stage column threads, which are easy to be aligned with the connection without mistakes. Reasonable interference design can achieve multiple connection without sticking. The joint strength can reach 100% of the pipe body strength under the tension, compression, internal pressure, and external pressure load.

4.Non-thread oil products

The non-thread oil technology has significant advantages  over the traditional thread oil spreading technology. If  there is no additional factor affecting connection, the  buckling effect is highly consistent, the operation time is  greatly reduced; the operation efficiency is improved and  there is zero pollution to the site environment. The  combination of the non-thread oil technology  and premium  connection  can satisfy  the requirements on  repeated use,  and can pass  the evaluation test of  ISO 13679 CAL  IV.
