ASTM A403 WP316L-S Stainless Steel Pipe Fittings ANSI B16.9 BW Elbow Reducer

ASTM A403 WP316L covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material of pipe fittings shall include forgings, bars, plates or seamless or welded pipes. Forging or forming operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or a combination of two or more of these operations. All accessories should be heat treated.

Chemical and product analysis should be performed and should meet the required chemical composition of carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum and titanium. Tensile tests should be performed on fitting materials to determine tensile properties such as yield strength and tensile strength. Accessories supplied in accordance with this specification shall be visually inspected for surface discontinuities, surface inspections, and mechanical markings.
Butt welded pipe fittings are designed to be field welded at their ends to join pipes together and allow for changes in direction or pipe diameter, or branching or ending.
The accessory then becomes part of a system for transporting fluids (oil, gas, steam, chemicals...) over short or long distances in a e and efficient manner.
Other types of fittings can be threaded or socket welded.
