Stainless steel elbows, common fittings in piping systems, are subject to a variety of standards for production and use. Commonly used stainless steel elbow standards primarily include the following:
1. Domestic Standards (China)
GB/T 12459-2017 "Steel Butt-Weld Seamless Pipe Fittings"
Specifies the dimensions, tolerances, and technical requirements for seamless butt-weld elbows made of stainless steel, alloy steel, and carbon steel.
GB/T 13401-2017 "Steel Butt-Weld Pipe Fittings"
Applies to welded elbows, tees, reducers, caps, etc.
GB/T 10752-2005 "Steel Elbows"
Specifies the technical parameters for elbows of different angles (such as 45°, 90°, and 180°).
GB/T 12459 and SH3408 and SH3409 (Petrochemical Standards)
Commonly used standards in the petrochemical industry impose stricter requirements on high-temperature and corrosion-resistant stainless steel elbows. 2. International Standards
ASME/ANSI B16.9 "Factory-Made Wrought Butt-Welding Fittings"
The most widely used international standard for butt-welding pipe fittings, covering elbows, tees, reducers, caps, and more.
ASME B16.11 "Forged Fittings, Socket-Welding and Threaded"
Mainly for small-diameter, stainless steel socket-welding and threaded elbows.
MSS SP-43
Specially for lightweight stainless steel butt-welding fittings (commonly used for low-pressure, thin-walled stainless steel pipe).
3. European Standards
EN 10253-4 "Butt-welding Pipe Fittings – Stainless Steels"
Applies to stainless steel butt-welding elbows, commonly used in EU countries.
DIN 2605
German standard that specifies the types and sizes of steel elbows. IV. Common Elbow Angle and Radius Standards
Angles: 45°, 90°, and 180° (common), with custom angles such as 30° and 60° available.
Bending Radius:
Short Radius (SR): Radius R = 1D (pipe diameter).
Long Radius (LR): Radius R = 1.5D (common).
Radiuses of 2.5D or larger may be used in special projects.
