There are many types of premium connection mainly for good sealing performance, resistant to high torque and damage repairing etc. We establish strategic partner with many famous mills such as Baosteel, TPCO, valin and so on who through the international certification .
We can supply many kinds of application connections including threaded and coupled connections, flush and semi-flush joint connection without coulple.
Integral Upset Connection
A kind of flush thread connection with pipe end upset. It can increase the ability of thread connection strength and resistance to bending. Two-step thread can improve the efficiency of field operation. Using tapered to tapered surface as the structural design of the main seal, provide good gas sealing performance; the external torque shoulder can achieve precise control; thickening of the inside and outside reverse torque shoulder can effectively prevent the plastic deformantion under high compressive load.
Fast Driven Connection
Obviously, driving connection fast. Deep oil and gas exploration means longer casing strings in big sizes. Short running times and safe make-ups can be achieved from Fast Driven Connections.
