Bend Radius for API 5L Pipe
Bend Radius for API 5L Pipe
(OP)
I am looking to calculate the bend radius of a API 5L fitting. Are you aware of charts or a simple method to calulate this? I need to run an internal inspection device in a pipe and it will only pass a 3D bend.





RE: Bend Radius for API 5L Pipe
1.5 D Bend has a centerline radius of 1.5 * pipe diameter,
so the 1.5D radius for 12" diameter pipe is 18",
3 D is 3 x Diameter, centerline radius for a 36" pipe is 9 feet.
For field or non-standard bends made from pipe, see ASME B31.4 Section 406.2
Most large diameter (>=24"D) field bends are typically done at 1ยบ change in direction in each length of 1 Diameter. (leave 1 diameter of straight length at each end of all pipes used to make the bend.)
