AWWA standards describe minimum requirements and do not contain all of the engineering and administrativ
3、e information normally contained in specifications. The AWWA standards usually contain options that must be evaluated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA pub- lication of a standard does not constitute e

All Rights Reserved. ix The design techniques described in AWWA Manual M11, Steel PipeA Guide for Design and Installa
20、tion, are used to determine the minimum wall thicknesses of steel pipe. Pipe-wall thickness to meet the design requirements will be determined by the appropriate formulas in AWWA Manual M11 using stainless-steel material properties. The purchaser shall establish and specify the minimum wall thicknes
21、s determined to be satisfactory for the service conditions of the pipe. Alternatively, the purchaser may provide the performance criteria for the pipeline and request the manufacturer to design the pipe for purchaser acceptance. The purchaser should consider the proper - ties of the lining and coati
22、ng materials, if specified, when selecting design stresses and deflection limits. The manufacturer may select materials and manufacturing processes within the limitations of this standard to produce pipe of the minimum wall thickness as specified or approved by the purchaser. II.A.1 Application. The
23、 provisions of this standard cover the requirements for stainless-steel pipe for use in water treatment plants, water transmission and distribution systems, and other water facilities. The purchaser is responsible for determining whether any unusual circumstances related to the project require addit
24、ional provisions that are not included in the standard. Such special conditions might affect design, manufacture, quality control, corrosion protection, or handling requirements. II.A.2 Testing of Special Sections. Sec. 5.2.2.1 describes nondestructive testing methods for weld seams of special secti
25、ons that may be necessary by request of the purchaser. The requirement for this special testing should be specified at the time of purchase. II.A.3 Roundness of Pipe. The roundness of pipe during handling, shipping, joint makeup, and backfilling should be specified by the purchaser. Pipe may have to
26、 be stulled to remain round. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. The following inf
27、ormation should be provided by the purchaser: 1. Standard usedthat is, AWWA C220, Stainless-Steel Pipe, 1/2 in. (13 mm) and Larger, of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is required. 3. A description and/or drawings detailing the total quantity of pipe required for each diameter.
