Overview:
WP304L Elbow is a type of pipe fitting that is made from grade 304L stainless steel. It is designed to connect two or more sections of piping systems and change the direction of flow. The "WP" prefix stands for "wrought pipe" and indicates that the elbow is made from a seamless pipe rather than a welded one.
The grade 304L stainless steel used to manufacture WP304L Elbows is a low-carbon variant of 304 stainless steel, which makes it more resistant to sensitization during welding. This type of elbow is commonly used in a range of industries such as chemical processing, food and beverage, oil and gas, and pharmaceuticals.
WP304L Elbows are available in a range of sizes and are available in different degrees of bends, including 90-degree, 45-degree, and 180-degree bends among others. These fittings are also commonly available in other standards such as ANSI, DIN, and JIS.
