Tubing Coupling Specification

All of crossovers and couplings  are produced and processed according to,with materials of steel grade including J55,K55,N80,N80-1,N80-Q,L80,P110 and so on.By numerically controlled lathe and import molding cutter,the processing of thread can be finished in one time,which ensures its commonality and interchangeability.we have complete testing abilities,adopting a whole set of single testing apparatus of thread,including tape,pitch,tooth depth and profile.Our products have already passed the identification of the Quality Testing and Inspection Center of Oil Pipe of CNPC(China National Petroleum Corperation).The pup-joints' any size,length,grade and weight is available on customer request. 

It realized to connect the two different specifications of tubing pipes. The placement is male; well mechanical properties,good sealing and connectivity.

After hot rolling, we can sure the coupling joint has well-proportioned and consistent metallographic structure. Good sealing and loading capacity.

Coupling is the joining of two short length pipes by the means of male and female threads.
