6. Manufacture
6.1 Forging or shaping operations may he performed by hammering, pressing, piercing, rolling, extruding, upsetting, bending, fusion welding, machining, or by a combination of two or more of these operations. The forming procedure shall be so applied that it will not produce injurious defects in the fittings.
6.2 Fittings ordered as Class WP***S shall be of seamless construction and meet all requirements of ASME B 16.9.
6.3 Fittings ordered as Class WP***W shall meet the requirements of ASME B16.9 and shall have full penetration fusion welds radiographically examined throughout their entire length in accordance with Paragraph UW-5 I of Section VIII, Division 1. of the ASME Boiler and Pressure Vessel Code. The radiography of this class of fittings may he done either prior to or after forming at the option of the manufacturer.
6.3.1 All welds shall he made in accordance with procedures by welders or welding operators qualified under the requirements of the ASME Boiler and Pressure Vessel Code, Section IX.
6.3.2 Personnel performing NDE examinations shall be qualified in accordance with SNT-TC-IA.
6.4 For welds made in accordance with the ASME Boiler and Pressure Vessel Code, Section IX, the joint shall be reinforced at the center of the weld by at least ‘/16 in. (1.6 mm) but not more than /8 in. (3.2 mm). Unless otherwise agreed upon between the producer and the purchaser, this reinforcement may be removed at the producer’s option. The contour of the reinforcement shall be smooth, with no valley or groove along the edge or in the center of the weld, and the deposited metal shall he fused smoothly and uniformly into the surface of the original material. The finish of the welded joint shall be reasonably smooth and free of irregularities, grooves, or depressions.
7. Responsibility for Quality Assurance
7. 1 Responsibility for Inspection and Tests—Unless otherwise specified in the contract or purchase order, the producer is responsible for the performance of all inspection and test requirements specified herein. Except as otherwise specified in the contract or order, the producer may use his own or any other suitable facilities for the performance of the inspection and test requirements specified herein, unless disapproved by the purchaser. The purchaser shall have the right to perform any of the inspections and tests set forth in this specification where such inspections are deemed necessary to assure that material conforms to prescribed requirements.
7.2 Lot Definition—An inspection lot shall consist of all fittings of the same alloy, size, shape, and dimensions subjected to inspection at one time.
8. General Quality
8.1 The sizes, shapes, and dimensions, and, unless otherwise specified, the end preparation (Note 2), shall be as specified for fittings covered by ASME B 16.9 and B 16.11.
