Coupling/Pipe Coupling

Pipe coupling is a very short pipe or tube used for connecting two oil pipes. It has a socket at one or both ends which allow two oil pipes to be joined, welded, brazed or soldered (copper, brass etc.) together. If the two ends of a coupling are different, then it is usually referred to as an adapter. We produce steel couplings of J55, N80 and P110 steel grades. These pipe couplings include casing coupling and tubing coupling.

1. This product has passed ISO9001 quality system assessment and the API certification from the American Petroleum Institute.
2. Our company manufactures these steel coupling according to the latest standards of API5CT specification. The ex factory pass rate of the product reaches 100%.
3. The pipe couplings have plain or upset ends.

1. The steel coupling is mainly used to connect oil pipes in oil drilling.
2. This product can be used to connect the shafts of units that are manufactured separately.
3. It can fit the misalignment of the shafts or introduce mechanical flexibility.
4. The pipe coupling is capable of reducing the transmission of shock loads from one shaft to another.
5. It can also introduce protection against overloads.
6. The steel coupling can be used to alter vibration characteristics of rotating units.
7. Pipe coupling is also used to connect driving part and driven part.

1. Perform visual inspections, such as checking for signs of wear or fatigue and cleaning couplings regularly.
2. Check and change lubricant regularly. The maintenance for the pipe coupling is required especially for most couplings in adverse environments or in different operating conditions.
3. Keep a record of the maintenance performed on each steel coupling.

We accept 30% T/T advance payment or letter of credit.

Pipe couplings are packed in containers and are transported by sea.
