6.3.3 Grade C95 Grade C95 pipe shall be subjected to no tensile or expansion cold-working, except that which is incidental to normal straightening operations, and to no more than 3 % compressive cold-working, after the final tempering operation. I Additional requirements for PSL-2 and PSL-3 products are specified in Annex H. 6.3.4 Grades C90 and T95 Grades C90 and T95 pipe may be subjected to cold rotary-straightening if, subsequent to the cold rotary- straightening operation, the pipe is heated to a minimum temperature of 480 OC (900 OF) for stress-relieving. When necessary, light gag-straightening for Grades C90 and T95 shall be permitted. I Additional requirements for PSL-2 and PSL-3 products are specified in Annex H.
