ANSI B16.5 / ASME B16.47 Weld Neck Flange Supplier, Manufacturer

We are one of the most effective Manufacturers of Weld Neck Flange in India. Our Material can reach the necessities of ASME standard. Quality is that the very important point in our business. And make sure that all the raw materials are 100% inspected absolutely consistent with our customers’ request. A Weld Neck Flanges also called a high-hub flange and tapered hub flange is a sort of flange. There are two designs. The regular type is used with pipes. A weld neck flange consists of circular fittings with a protruding rim around the circumference. This weld neck flange is typically butt welded to a pipe. The rim includes a series of drilled holes that allow the flange to be affixed to a different flange with bolts. WNRF has a neck that will relocate the strain of the pipe, so to reduce the pressure that gathered within the flange bottom. it’s compatible with the pipelines that work in high or low temperatures and bear high. Weld neck flange has two shapes, one with reducing neck as we called the reducing weld neck flange and One with a good diameter of typical long neck named as long weld flange. Like its name, it’s sort of a combination of pipe reducer and flange, so it can be welded to a smaller pipe directly. Gasket seats are placed during this raised area. depending on the various pressure ratings, the various heights of raised faces are adopted. The ring-joint sort of WN flange has a specially made groove, here you’ll place a metal gasket seat to seal the connections. So this sort of SW flange is used in heat and high-pressure services. The installation cost of the welding neck flange, and auxiliary materials costs are higher because there’s more than one process.
