FOREWORD This Specification was prepared by a formulating committee on which were representatives of the American Petroleum Institute@ the American Gas Association@ the Pipe Line Contractors Association@ and the National Electric Manufacturers Association@ also representatives of the pipe manufacturers and individuals associated with related industries. It is the purpose of this Specification to insure the production of the highest quality welds obtainable on a commercial basis by skilled welders@ using approved welding procedures@ materials@ and equipment. It is also the purpose of this Specification to insure the production of the highest quality radiographs obtainable by skilled operators@ using approved technique and equipment@ to insure the proper analysis of welding quality and defects. This Specification is intended to apply only to cross country pipe lines for the transmission of crude petroleum@ petroleum products and natural gas. The Committee has had the cooperation of many engineers interested in design@ construction@ and operation of oil and gas pipelines@ and desires to express appreciation for their wholehearted and valuable assistance. It is realized that revisions will be necessary from time to time to keep abreast of developments@ and constructive suggestions will be welcome. Publication of the Specification presented herein has been authorized by the American Petroleum Institute and the American Gas Association.
