ASTM A403 / ASME SA403 / EN10253-4 WP304 1.4301 STAINLESS STEEL BUTT WELD ELBOW
Overview:
WP304 elbow refers to an elbow fitting made from stainless steel grade 304 (WP304). Stainless steel grade 304 is a commonly used austenitic stainless steel known for its excellent corrosion resistance, durability, and versatility. WP304 elbows are widely used in various industries such as petrochemical, food and beverage, pharmaceutical, and process piping systems.
These elbows are typically manufactured through the butt-welding process, where two pipes are joined together by welding. WP304 elbows are available in different sizes, ranging from small diameters for residential or commercial applications to larger diameters for industrial purposes. They come in various angles such as 45 degrees, 90 degrees, and 180 degrees to facilitate changes in direction for fluid or gas flow within a piping system.
WP304 elbows adhere to specific standards such as ASTM A403 and ASME B16.9, ensuring their dimensional accuracy, material composition, and manufacturing quality. These standards outline the requirements for design, dimensions, materials, markings, and testing procedures to ensure reliable and e performance of WP304 elbows in various applications.
