API 5L X60 BENDS are made out of API 5L X60 seamless pipes or welded pipes,which are widely applied in the oil&gas pipelines to change the directions of medium flow its advantage that can match long distance transition requirements,so it is commonly that bends dimension according to customer design. Normally,the bends consist of 3D, 5D, 7D and 12D series and have the tangents of 500/1000mm on both ends.

Chart of bends structure                                    
Calculation Formula:
L = R x B
L = Length of pipe required
R = Radius of bend
B = Constant from table used to find "L"
L =30 x 1.5705 =47.115 in.or 47-1/8"
Pressure: SCH5 to SCH160
Bending radius(R): R=3D, 5D, 7D and 12D
Bending angle (θ):15°, 30°, 45°, 60°, 90°, 135°, 180°

Outer diameter(D): D≤1800mm
Wall thickness(T): T≤120mm
Straight Length (L): The length between two ends general from 300mm-1500mm
Example: Find the length of pipe required to make a 90 bend with a radius of 30"
