Welding of gasketed joints may require modification to the parameters of this welding standard. This standard recognizes AWS D1.1 as the supporting document. The design of field-welded joints is not covered within this standard. However, when possible, pipe fabrications and fittings should be performed by the manufacturer at a manufacturing facility. This standard also applies to other welding required in field fabrication and installation of specials and appurtenances. 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 describes manual, semiautomatic, and automatic field welding by the metal arc-welding processes for steel water pipe manufactured in accordance with ANSI/AWWA C200, Standard for Steel Water Pipe-6 In. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.įinal publication of the standard may take several months.
