Description
API Tubing SC Coupling PSL2 L80 EUE
Tubing coupling is manufactured by the coupling stock (thicked-wall pipes),used for the connect to the tubing string in the oil well.
As per the thread thype,the TBG coupling can be divided into NUE Coupling,EUE coupling,Premium thread Couplings.Also it can be coupling with seal ring,Combination coupling,Special chamfered coupling,Extended coupling,internal coating couplings,PSL2 Coupling and D10 Coupling considering the different useage.
Our team pay more attention to the coupling inspection,The measurement and inspection of coupling threads and threads should comply with the requirements of API 5B. Do not use the method of expanding to achieve the required thread taper for couplings with API threads.
All couplings should undergo inner and outer surface inspection after final processing and before electroplating on the inner or outer surface. The circumferential magnetic field wet fluorescent magnetic particle method of ISO 13665 or ASTM E709 should be used to inspect surface longitudinal defects, or it should be proven to have other non-destructive testing methods with the same sensitivity shall be used for inspection.
