Product Details
3/4" 7/8" 1" T Sucker Rod Coupling SM SH FS Coupling
Product Description
1.The sucker rod coupling have the same box thread size in each end are used for connecting
sucker rod and/or pony rod, and/or sinker bars with sucker rod
threads.
2.The polished rod coupling have the same box thread size in each end
are used for connecting polished rod and/or sinker bars with
polished rod threads to the sucker rod string.
3.The sub-coupling have different sizes of box threads in each end
are used for connecting two sizes of sucker rods or a polished rod
to a sucker rod string.
4.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.
5.The couplings 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.
