รายละเอียดเอกสาร

This standard describes manual, semiautomatic, and automatic field welding by the metal arc-welding processes for steel water pipe manufactured in accordance with ANSI*/AWWA C200, Steel Water Pipe—6 In. (150 mm) and Larger. This standard describes field-performed full circumferential welding of three types of pipe joints: (1) lap joints, (2) butt joints, and (3) butt-strap joints. This standard also applies to other welding required in field fabrication and installation of specials and appurtenances. However, when possible, pipe fabrications and fittings should be performed by the manufacturer at a manufacturing facility. The design of fieldwelded joints is not covered within this standard.
