# §192.717. Transmission lines: Permanent field repair of leaks.


Each permanent field repair of a leak on a transmission line must be made by—

- (a) Removing the leak by cutting out and replacing a cylindrical piece of pipe; or
- (b) **Repairing the leak by one of the following methods—**
  - (1) Install a full encirclement welded split sleeve of appropriate design, unless the transmission line is joined by mechanical couplings and operates at less than 40 percent of SMYS.
  - (2) If the leak is due to a corrosion pit, install a properly designed bolt-on-leak clamp.
  - (3) If the leak is due to a corrosion pit and on pipe of not more than 40,000 psi (267 Mpa) SMYS, fillet weld over the pitted area a steel plate patch with rounded corners, of the same or greater thickness than the pipe, and not more than one-half of the diameter of the pipe in size.
  - (4) If the leak is on a submerged offshore pipeline or submerged pipeline in inland navigable waters, mechanically apply a full encirclement split sleeve of appropriate design.
  - (5) Apply a method that reliable engineering tests and analyses show can permanently restore the serviceability of the pipe.
