Replace the existing Clause 7 with the following:
7 Bending and other forming
7.1 General
7.1.1 Fabricators of formed pressure parts shall have adequate procedures, equipment and tools for the

consideration. Account shall be taken of the recommendations of the steelmakers.
Pipes whose properties have been generated by thermomechanical means such as controlled rolling can be
formed by cold methods. Such materials may be substantially changed by the forming process and require
particular consideration to ensure that the specified properties are recovered after forming.
