Introduction of JIS B2312 WP304 Elbow


JIS B2312 WP304 elbow is a stainless steel butt‑welding pipe fitting conforming to Japanese Industrial Standard JIS B2312, made from ASTM A403 WP304 (equivalent to SUS304, 1.4301). It features excellent corrosion resistance, good weldability, and stable mechanical performance, widely used in general industrial, water treatment, food processing, and low‑pressure piping systems. Available in 45° and 90° types with long or short radius, it is designed for butt‑weld connection with various pipe schedules.

Due to its reliable quality and compliance with JIS standards, it ensures safe and durable operation in medium‑pressure pipelines. Strict dimensional control, heat treatment, and non‑destructive testing are applied during manufacturing to meet industrial quality requirements.

 

 

Features of JIS B2312 WP304 Elbow

 

  • Manufactured to JIS B2312 (Japanese standard for steel butt-welding fittings) and ASTM A403 WP304 (SUS304/1.4301) austenitic stainless steel.
  • Excellent corrosion resistance in atmosphere, freshwater, and mild chemical environments.
  • Good formability, weldability, and heat stability for medium-pressure service.
  • Available as 90° and 45° elbows, long radius (LR) and short radius (SR).
  • Butt-weld end with standard bevel for reliable pipeline connection.
  • Wide size range (DN15–DN600) and various wall thickness schedules.
  • Strict dimensional accuracy, heat treatment, and NDT ensure stability and safety.
  • Widely used in water treatment, HVAC, food, chemical, and general industrial piping.
