We are manufacturer of Socket Welding Coupling and supplies full coupling,half coupling in kinds of materials such as carbon steel, stainless steel, alloy steel.
Stainless steel pipe coupling is popular becasue of the corrosion resistance, long service life and strong connection. We supply socket weld pipe fittings in various stainless steel grades such as the commonly used grades SS304 and SS316.
Pipe coupling is a short piece of pipe that used to connect pipes together, socket weld coupling has socket weld ends.
Full Coupling: That means the two ends of pipe coupling are socket welding.
Half Coupling: One end of half coupling is socket weld and the other end is welding.
Straight Coupling: That means the diameter of the two ends are the same.
Reducing Coupling: The diameter of the two ends are different.
