KOC Approved Stainless Steel Coupling Manufacturer In India And ASME B16.11 SW Half Couplings Material Specification/ Dimensions/ Weight.
What Is A Socket Weld Half Coupling?
Stainless Steel Socket Weld Coupling is a coupling with a socket weld only at one end. Couplings are fittings used to connect two pipes closer in piping systems. Couplings can use threads or socket welds to connect. If they have the socket or threads on both sides, they are called full couplings. The ASME B16.11 Coupling is the range of diameters up to 4 inches. The Socket Weld Coupling uses socket welds at the ends to allow the pipe inside the coupling and to weld. They have different pressure classes such as the SW Coupling Class 150. For extra strength the Forged Coupling Dimensions can include higher wall thickness.

Stainless Steel Socket Weld Coupling Use In Higher Pressure Class?
The difference in Stainless Steel Socket Weld Coupling Dimensions can also be due to the application requirements and the piping to fit in. Different materials are used in production such as the Socket Weld Coupling Stainless Steel or the Carbon Steel Socket Weld Coupling which ensure certain mechanical properties. Larger couplings should conform to higher pressure classes such as the Class 3000 Socket Weld Coupling which can stand up to 3000lbs of pressure.
Carbon Steel Socket Weld Coupling Used With Straight Line Piping?
Stainless Steel Socket Weld Coupling has the socket weld only on one side of the coupling. Socket Weld Half Coupling Dimensions vary at both ends as the recession on one end make it wider than the other end. The Forged Half Coupling is used with straight line piping. 3000# Socket Weld Coupling Dimensions differ in wall thickness mainly to accommodate the pressure containment of the class. The stronger Forged Pipe Coupling can either be a Forged Steel Half Coupling or a Carbon Steel Socket Weld Coupling depending on the needed material. The pressure classes can be 2000, 3000 or 6000 as denoted in the cases of 3000 Lb Socket Weld Coupling or the much heavier 6000# Socket Weld Coupling. The usage of the Socket Weld Pipe Coupling is wide in almost all industries that use pipes. Low pressure environments such as water lines could use lower pressure classes such as the Socket Weld Coupling Class 150. But the Pipe Coupling Socket Weld can be applied to high temperature and high pressure applications as well.
