# §195.212. Bending of pipe.

- (a) Pipe must not have a wrinkle bend.
- (b) Each field bend must comply with the following:
  - (1) A bend must not impair the serviceability of the pipe.
  - (2) Each bend must have a smooth contour and be free from buckling, cracks, or any other mechanical damage.
  - (3) On pipe containing a longitudinal weld, the longitudinal weld must be as near as practicable to the neutral axis of the bend unless—
    - (i) The bend is made with an internal bending mandrel; or
    - (ii) The pipe is 12 3/4 in (324 mm) or less nominal outside diameter or has a diameter to wall thickness ratio less than 70.
- (c) Each circumferential weld which is located where the stress during bending causes a permanent deformation in the pipe must be nondestructively tested either before or after the bending process.
