Haige offers Class T Sucker Rod Couplings and SM Sucker Rod
Couplings.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.
