Description

PI Alloy Steel Polish Rod Coupling OD16 ~ 38mm AISI 5140 Material Rod Coupling

Products Description:

The Sucker Rod Coupling are available in full size, slim hole and over size Also, combination couplings are available for different diameters (sub-coupling) for both Class T and Class SM couplings. The class T and class SM coupling for sucker rods are manufactured as per API Specification 11B. For the thread cutting, we are using cold form rolled by displacing rather than by removing of material for making the coupling thread. The thread rolling cutting results in a compressive stress at the root of the thread, giving maximum strength to the traditional weak point of cut-thread couplings. We recommend changing sucker rod couplings after three make-ups, provided the connection threads have been inspected and deemed acceptable for reuse.
