Product Description:

API STC Casing Couplings

We provide STC casing coulings from 4-1/2″ to 20″, in grade J55, K55, N80, L80 and P110.

Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For all casing sizes, the threads are not intended to be leak resistant when made up.

The round-thread (STC or LTC) casing-joint strength is given as the lesser of the fracture strength of the pin and the jump-out strength.

Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
Q:I would like to ask who has 24 degrees taper hydraulic pipe joint processing drawings, please send me, thank you very much
To use their own drawings approved by the good deeds since then, almost no tiny bit. PM me when needed ~!
