Weld Neck Flanges

Manufacturer Of ASME / ANSI B16.5 Weld Neck Flanges, ANSI B16.5 Weld Neck Flanges Supplier in India.

In order to enable sturdy and dependable connections between pipes, valves, and other equipment, weld neck flanges are an essential part of pipeline systems. One of its distinguishing features is their tapered neck, which offers a seamless transition from the pipe to the flange. Because of their reduced turbulence and stress concentrations, weld neck flanges are the best choice for high-pressure and high-temperature applications. A circular plate with a raised or flat face is welded to the end of a pipe to form the flange. In order to facilitate a seamless welding joint that strengthens the connection, the flange's neck is often tapered to match the outer diameter of the pipe. Additionally, by equally spreading stresses, this design lowers the possibility of leaks and breakdowns under difficult circumstances.
To guarantee a solid, leak-proof connection during installation, weld neck flanges require accurate alignment and welding processes. The flange cannot function as intended or last as long without proper surface preparation and welding standards compliance. To sum up, weld neck flanges are prized for their sturdy construction and capacity to withstand harsh circumstances.
