Couplings are used to connect two joints of TUBING coupling or CASING pipe together.
Couplings are short length of heavy wall pipe with the same threads on each end.
The steel coupling is mainly used to connect oil pipes in pil drilling.
This product can be used to connect the shafts of units that are
manufactured separately.
It can fit the misalignment of the shafts or introduce mechanical flexibility.
The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another.
It can also introduce protecyion against overloads.
The steel coupling can be used to alter vibration characteristics of
rotating units.
Pipe coupling is also used to connect drilling par and driven part.
