Dear Mr. Rumble:
This responds to your letter of May 2, 1978, concerning the requirements of Section 192.105(b) of Part 192, Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety
Standards. This Section limits the design pressure of steel pipe that has been cold worked to meet SMYS to 75 percent of the pressure determined under Section 192.105(a) if the pipe is heated, other than by welding, to 600mF or more.
The term "cold worked" does not relate to thermo-mechanically rolled steel plate that is later made into pipe. It does relate to pipe that has been "cold expanded."
The 600mF limitation on the heating of such "cold worked" pipe was adopted directly from U.S.A.S. B31.8, Code for Pressure Piping, Gas Transmission and Distribution Piping Systems, 1968 edition.
If we may assist further please let us know.
Sincerely,
/signed/
Cesar DeLeon
