What is Coupling?

Welded Coupling is a type of straight fitting used to connect two ends of pipes together.


There are two types of connections, threaded and welded. Depending on the intended use, people will have specific requirements on technical standards for each type of coupling.

Materials for Coupling production can be ductile cast iron, ss400 steel, and A105 steel specialized for high-pressure pipeline systems.

Typically, couplings will be in sizes D13 to D114, sometimes going up to D273 for bored pile pipes. (This type we can also produce to order).

Couplings and elbows are two names for the same product.

The northern region of Vietnam often calls it an elbow (sometimes misinterpreted as a 90-degree Elbow ). As for the southern region, it is often clearly called Coupling.

Coupling for connecting steel pipes produced by Bao Tin Steel Co., Ltd. has guaranteed quality, and extremely cheap price because it is a direct manufacturer.
Welding coupling is used for connecting ultrasonic pipes in Ho Chi Minh City and Phnom Penh.
