ASTM A815 WPS32205 Duplex 2205 180 degree U Bend Pipe
We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
ASTM A815 specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic stainless steel fittings of seamless and welded construction. Class WP fittings are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations. The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature. Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen, and titanium. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.
