GOST Elbow LR/SR 45/90/180DEG

The GOST Elbow is a pipe fitting specified by the Russian GOST (Gosudarstvennyy Standart) standards. It serves the purpose of connecting pipes at different angles.

1. Design and Dimensions:
   • The GOST Elbow comes in two variations:
     • Long Radius (LR) Elbow: These elbows have a larger radius of curvature, resulting in a smoother flow transition.
     • Short Radius (SR) Elbow: These elbows have a smaller radius of curvature, making them more compact.
   • The elbow is designed for butt-welding to pipes.
2. Materials:
   • These elbows can be made from various materials, including carbon steel, stainless steel, alloy steel, and high nickel alloys.
3. Dimensions:
   • Available in sizes ranging from ½ inch (15 NB) to 48 inches (1200 NB) or DN10~DN5000.
   • Wall thickness varies based on the outside diameter.
4. Pressure Ratings:
   • The elbow’s pressure ratings adhere to the ANSI Class standards, including 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, and 2500 LBS.
5. Applications:
   • GOST Elbows find use in various industries, including bitumen upgraders, heavy oil refineries, nuclear power production, petrochemicals, and acids.
