was downhill 5P and occassionally dual shield. The most common welding procedure being used during the late 90s on these lines in SOCA and Nv. It is essentially AWS D1.1 as applied to large bore water line, with a couple of qualifiers. The code, while not lax, takes very little responsibility for self-definition. When I contracted my own 42" line and had to learn what I was up against in AWWA, I burnt a lot of time and miles talking with CWIs. With that said: rfieldbuilds speaks correctly. I am neither an engineer nor a CWI, but I make the point on a job to either be conversant in the code expectations for the welding I will be doing or to learn them PDQ. Ĭactus- Regarding your waterline AWWA question: I've worked 5 large bore waterlines as a rig welder, one 42" short line I contracted myself, so I have some experience but there are others who specialize in that niche and can speak more authoritavely than myself. Looks to me the welding falls under D1.1 but I dont have 65 to 72 dollars of curiosity. Welding of gasketed joints may require modification to the parameters of this welding standard. This standard recognizes ANSI/AWS D1.1 as the supporting document that provides more specific information. The design of field-welded joints is not described.
Other welding required in field fabrication and installation of specials and appurtenances is also discussed. This standard describes field welding of three types of circumferential pipe joints: (1) lap joints (2) butt joints and (3) butt-strap joints. Cactus, I did a search and found this 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.
