Rajveer Stainless and Alloys is a manufacturer and supplier of Pipes Fittings as per ISO 9001, ISO 140001:2015, OHS 18001: 2007, & PED 2014 / 68 / EU certifications. ASTM A403 WP316 Pipe Fittings cover the standard for wrought austenitic stainless steel fittings for pressure piping applications. The fitting material consists of forgings, bars, plates, and seamless or welded tubular products. Shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by a combination of any of them. At RSA all fittings undergo heat-treatment.

ASTM A403 WP316 LR Buttweld Pipe Elbow chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum and titanium. Tension test is done on the fitting material to determine the tensile properties such as yield strength and tensile strength. ASTM A403 WP316 90 Deg. Short Radius Elbow supplied under this specification are examined visually for surface discontinuities, surface checks and mechanical marks.

ASTM A403 WP316 180 Degree Elbow is designed to be welded on site at its end to connect pipes together and allow change in direction or pipe diameter or ending. ASTM A403 WP316 Fitting then becomes part of a system for transporting fluids like oil, gas, steam, chemicals, and so on in a safe and efficient manner, over short or long distances.

Several grades of austenitic stainless steel alloys are included in this specification. Grades are designated with a prefix, based on the applicable ASTM/ASME or MSS standards. For each of the WP stainless grades, several classes of fittings are specified, to indicate whether seamless or welded construction was utilized. Class designations are also utilized to indicate the non-destructive test method and extent of nondestructive examination. ASTM A403 Grade WP316L Properties include 485 tensile strength, 170 yield strength and 40% elongation.
