33、 foreword is for information only and is not a part of ANSI*/AWWA C206. I. Introduction. I.A. Background. The provisions of this standard describe the requirements for welding steel water pipe joints in water transmission and distribution lines. The purchaser for each project is responsible for dete
34、rmining if any unusual circumstances related to the project require additional provisions that are not included in the standard. The design of field-welded joints is not discussed in this standard. Useful informa - tion on this subject may be found in AWWA Manual M11, Steel PipeA Guide for Design an
35、d Installation, and in Useful Information on the Design of Plate Structures (American Iron and Steel Institute ). After the welded field joint has been completed, if the pipe has been coated or lined, the joint shall be coated and lined with a coating system compatible with that on the body of the p
36、ipe, in accordance with the requirements for field repairs stated in the appropriate AWWA coating or lining standard. For lap-welded pipe with an inside diameter equal to or exceeding 48 in. (1,200 mm) and where the purchaser deems single welding to be acceptable, inside welding is recom- mended. Sa
37、fety precautions shall be utilized in all pipe sizes, although when pipe with inside diameters less than 48 in. (1,200 mm) down to 27 in. (675 mm) is welded from the inside, additional safety precautions shall be observed. Interior welding on pipe diameters less than 27 in. (675 mm) is not recommend
38、ed. Pipe requiring inside welds with limited access should be supplied with 3-in. (75-mm) diameter weld lead pass holes at approximately 400-ft (122-m) centers to allow passage of welding leads to the joint location. Shorter distances between pass holes may be required, depending on actual project c
39、onditions. Pass holes in the pipe will permit shorter welding leads and thus avoid erratic voltage drops caused by excessively long welding leads. The pass hole is fabricated using a weldable-grade inside-threaded pipe half-coupling-welded to a hole cut through the pipe wall. After using the pass ho
40、le, a weldable-grade plug shall be threaded into the opening and seal-welded to secure. * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

42、 1946 and by the American Welding Society (AWS) in October 1945. It was advanced to standard status by AWWA in 1950 and by AWS in 1951. The joint AWWA- AWS activity continued through revisions in 1957 (AWWA C206-57, AWS D7.0-57) and 1962 (AWWA C206-62, AWS D7.0-62a). The joint committee was dissolve
43、d in 1971, and the standard was assigned to the AWWA Standards Committee on Steel Pipe. Subsequent editions of the standard were published in 1975, 1982, 1988, 1991, 1997, 2003, and 2011. This edition was approved by the AWWA Board of Directors on Jan. 14, 2017. I.C. Acceptance. In May 1985, the US
44、Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF*) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium i
45、ncluded the Water Research Foundation (formerly AwwaRF ) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate pr
46、oducts for use in, or in contact with, drinking water rests with individual states. Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies m
47、ay use various references, including 1. Specific policies of the state or local agency. 2. Two standards developed under the direction of NSF: NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 3. Other references, includin
48、g AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to a
