Butt Weld Fittings ASTM A403 WP304-S Stainless Steel Seamless End Caps B16.9
ASTM A403 WP304 Stainless Steel Fittings are high pressure pipe fittings used in high pressure pipe lines. There are various kinds, shapes, sizes and grades of fittings. The fittings are used in high temperature applications because of the high melting point of the material. The material has 1400 degrees Celsius melting point and the fittings can operate at temperatures up to 870 degrees Celsius. Pipe Caps act as protective devices to close off the end of pipe and stop the flow of fluids. And they are widely used in various chemicals, construction industries, paper and pulp, cement & ship builders.Stainless Steel 304 Pipe Fittings provide high tensile strength, resistance to corrosion. The outstanding resistance to corrosion and reduced content of carbon along with high strength makes 304 SS caps useful in applications where welding is needed.
