API 5L Line Pipe 24inch SCH30 DRL Welded Carbon Steel Pipe
Treatment of weld seams in EW and LW pipes
API 5L Line Pipe 24inch SCH30 PSL 1 EW pipe
For grades higher than Grade L290 or X42, the weld seam and the HAZ shall be heat treated so as to simulate a normalizing heat treatment, except that, if agreed, alternative heat treatments may be substituted. If such substitutions are made, the manufacturer shall demonstrate the effectiveness of the method selected using an agreed procedure. Such a procedure may include, but is not necessarily limited to, hardness testing, microstructural evaluation or mechanical testing.
For grades equal to or lower than Grade L290 or X42, the weld seam shall be heat treated as to simulate a normalizing heat treatment, or the pipe shall be processed in such a manner that no untempered martensite remains.
API 5L Line Pipe 24inch SCH30 DRL LW pipe and PSL 2 HFW pipe
For all grades, the weld seam and the HAZ shall be heat treated so as to simulate a normalizing heat treatment.
