Elbows & Bends
Long Radius (LR) Elbows
Long Radius (LR) elbows have a centre-to-end distance equal to 1.5 times the nominal pipe size (R = 1.5D), providing a gradual change in direction that minimises pressure drop and flow turbulence. They are the most commonly used elbow type in process piping and are the default specification unless otherwise stated. Shree Raj Steels manufactures LR elbows in 45° and 90° configurations from 1/2" to 60" in all standard materials.
