Stainless Steel 304 Pipe Fittings

ASTM A403 WP304 Elbow pressure rating and A403 grade WP304 Tee class

Stainless Steel 304 Pipe Fittings

Stainless Steel 304 Fittings are used in low cost and domestic applications primarily. They could also be used in different industries according to the need and the modifications in grades. We produce different kinds of fittings. The buttweld fittings are special because they have beveled ends enabling much stronger connections between pipes, fittings or both of them. As the leading Stainless Steel 304 Pipe Fittings Manufacturer we offer a range of fittings such as flanges, unions, bends elbows and others.

Our SS 304 Fittings Price List is also very competitive. We offer our customers with the most cost effective solutions. There are different standards that govern the different aspects of the pipe fittings. There are grades to govern the material composition, standards to govern the nominal sizes and there are pressure classes and schedules that deal with the pressure containment and wall thickness aspects. The Werkstoff No 1.4301 Stainless Steel Fittings are such a special grade and have to be used as per the application requirements. We produce all these ranges. One of our products is the ASTM A403 WP304 Elbow. It could be used to change the direction of the pipe with an angle. The elbow could be short or long in radius. We produce ASTM A403 WP304 Reducer as well. A reducer reduces the fluid flow volume at the connection. All the SS 304 Pipe Fittings are specific in use cases and we manufacture all of them. Great Steel & Metals is produces UNS S30400 Sch 10 SS Fittings along with other schedules of fittings as well.
