ASTM A403 WP316L Stainless Steel Butt Weld 90° LR Elbow ASME B16.9 Class150
1. Product Description
Stainless Steel Butt Welding Elbow is a steel pipe fitting formed by hot pressing or forging. Its connection method is to directly butt weld the elbow with the steel pipe, creating a permanent, flush connection that enables maximum flow through the process line. The product is made of high-quality stainless steel (grades such as 304, 304L, 316, 316L, etc.), featuring excellent corrosion resistance, oxidation resistance, and high-temperature resistance. The product design complies with standard pipe fitting specifications to ensure seamless integration with same-specification pipelines.
2. Product Applications
This elbow is used to change the direction of piping in various industrial systems. Main applications include:
Petrochemical and chemical processing plants – for crude oil, refined products, and chemical feedstocks.
Water treatment and environmental protection – drinking water supply, sewage, and seawater desalination.
Food, beverage, and pharmaceutical industries – sanitary pipelines for clean media.
Power generation – boiler feedwater and steam lines.
Oil and gas – production fluids and natural gas transmission.
Marine and offshore engineering – seawater cooling and fuel oil systems.
Building and municipal engineering – water supply, drainage, heating, and gas distribution.
3. Product Advantages
Superior corrosion resistance – 304/316L grades resist pitting, crevice corrosion, and stress corrosion cracking, suitable for harsh environments.
High strength and durability – work hardening during forming provides excellent mechanical strength; service life can reach up to 100 years with low maintenance.
Leak‑proof permanent connection – butt welding ensures a seamless, reliable joint that eliminates leakage risks.
Smooth internal surface – reduces fluid friction, prevents deposit accumulation, and inhibits bacterial growth.
Material and energy saving – stamping process produces minimal scrap and requires no extra heating, making it efficient and eco‑friendly.
Quick installation – installation time is only one‑third of that for threaded or socket‑welded fittings, shortening construction schedules.
