# §192.715. Transmission lines: Permanent field repair of welds.


Each weld that is unacceptable under [§ 192.241(c)](/cfr/49/192.241.md?p=c) must be repaired as follows:

- (a) If it is feasible to take the segment of transmission line out of service, the weld must be repaired in accordance with the applicable requirements of [§ 192.245](/cfr/49/192.245.md).
- (b) A weld may be repaired in accordance with [§ 192.245](/cfr/49/192.245.md) while the segment of transmission line is in service if:
  - (1) The weld is not leaking;
  - (2) The pressure in the segment is reduced so that it does not produce a stress that is more than 20 percent of the SMYS of the pipe; and
  - (3) Grinding of the defective area can be limited so that at least 1/8-inch (3.2 millimeters) thickness in the pipe weld remains.
- (c) A defective weld which cannot be repaired in accordance with paragraph [(a)](#a) or [(b)](#b) of this section must be repaired by installing a full encirclement welded split sleeve of appropriate design.
