What materials are oil pipe couplings made of?

The structure of the oil pipe coupling is: the top of the oil pipe is connected to the inner wall of the coupling in the form of a tapered thread, and the top of the oil pipe coupling is connected to the oil pipe in the form of a flat thread with the same thread and pitch. It has the characteristics of reducing the stress concentration at the root of the external thread of the oil pipe of the single taper thread joint, making it less prone to fatigue cracking and the connection effect is obvious.

Reasonably and effectively avoid safety accidents such as oil well pipe string breakage. Oil pipe couplings, wear-resistant oil pipe couplings, extra large oil pipe couplings, wholesale oil pipe couplings, coupling manufacturers, L80 oil pipe couplings, various thread variable buckle oil pipe casing couplings, direct connection oil pipe couplings, Nitrided oil pipe coupling, Q125 material oil pipe coupling material, thick-walled seamless steel pipe coupling material. In order to avoid the oil pipe male thread and box thread (coupling) from sticking and being damaged during the tightening process, it is necessary to Phosphating treatment should be carried out on oil pipe couplings or casing couplings to effectively avoid thread damage after disassembly and assembly.

There are also many materials that are not suitable for phosphating. BCSG casing couplings need to be electroplated with copper-tungsten alloy to achieve the effect of wear resistance.
