Manufacturing note
A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. We, Nascentfit Piping Stainless Steel Flanges Manufacturers in India. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
