Types of thread commonly used UPTBG.TBG.EUE.NUE.LTC.BTC.STC,

Special buckle types VAM series NEW VAM.VAM TOP, etc., Haider series PH6 / CS, etc.

The structure of the tubing coupling is: the end of the tubing is connected with the inner wall of the coupling by a tapered thread, and the end of the coupling body and the tubing are connected by a flat thread with the same thread and the same pitch. It has the characteristics of alleviating the stress concentration at the root of the external thread of a single tapered threaded tubing, which is not prone to fatigue fracture and has a good connection effect.

Casing coupling model: 5-1 / 2 '; 6-5 / 8'; 7 '; 8-5 / 8'; 9-5 / 8 '; 13-3 / 8'; 16 '; 20' etc.

Casing coupling steel grade material: J55 / K55 / N80 / L80 / P110 / Q125 / 1CR / 3CR / 9CR / 13CR / Super13CR
