Elbow, Stainless Steel Elbow, Carbon Steel Elbow

SR (Short Radius) Elbows have a Center-to-Face dimension of 1.0 X diameter. They are typically used in tight areas where clearance is the main issue.
Elbow

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Short Radius (SR) Elbow is also called SR elbow, – means the radius is 1.0 times the pipe diameter
Short radiu 45°Elbow: Short radius 45° elbow changes the direction by 45 degrees.
Short radius 90°Elbow: Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
Short radius 180° Elbow: Short Radius 180° return bend allows complete reversal of flow

Sizes:
Seamless elbow: 1/2"-24" DN15-DN600
Welding elbow: 6"-72" DN150-DN1800
Wall thickness: Sch5-Sch160 XXS

Long radius elbow is the elbow which the radius of curvature of is 1.5 times the diameter of the pipe; if the radius of curvature is greater than 1.5 times, the long radius elbow will be called the bend. The short radius elbow means that the radius of curvature of the elbow equals the diameter of the pipe, or 1 time the diameter of the pipe in common words. D is used to represent the diameter of the elbow.

Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.

Sizes:

Seamless elbow: 1/2"-24" DN15-DN600
Welding elbow: 6"-72" DN150-DN1800
Wall thickness: Sch5-Sch160 XXS
