3、 document is an American Water Works Association (AWWA) standard. It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifi- cations. The AWWA standards usually contain options that m

4、ust 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 publication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve any product. The use

5、 of AWWA standards is entirely voluntary. This standard does not supersede or take precedence over or displace any applicable law, regulation, or codes of any governmental authority. AWWA standards are intended to represent a consensus of the water supply industry that the product described will pro

6、vide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the Official Notice section of Journal - American Water Works Association. The action becomes effective on the first day of the month following the month of Journ

7、al - American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the con

8、sumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. Ameri- c

9、an National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that

10、 the goods are produced in conformity with particular American National Standards. Caution n oti Ce : The American National Standards Institute (ANSI) approval date on the front cover of this standard indicates completion of the ANSI approval process. This American National Standard may be revised o

11、r withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

20、inimum wall thicknesses of steel pipe. The purchaser shall establish and specify the wall thickness determined to be satisfactory for design conditions. The purchaser should consider the proper - ties of the lining and coating materials, if specified, when selecting design stresses and deflection li

21、mits. Alternatively, the purchaser shall establish and specify the mini- mum wall thickness that will satisfy conditions of external pressure, trench loadings, a n d s pe c ia l p h y s i c a l l o a d i n g s .

22、rocesses within the limitations of this standard to produce pipe of the wall thickness required to additionally satisfy specified internal pressure. The purchaser shall specify the internal design pressure and show the depth of cover over the pipe together with installation conditions and details as

23、sociated with any special physical loading conditions. The manufacturer shall select and furnish pipe that has a wall thickness that meets the requirements of the internal design pressure and external load design. This thickness shall govern if it exceeds the minimum thickness specified by the purch

24、aser. Pipe-wall thickness to meet the design requirements will be determined by the appropriate formulas in AWWA Manual M11 using stainless steel material properties. II.A.1 Application. The provisions of this standard cover the requirements for stainless-steel pipe for use in water treatment plants

25、, water transmission and distribution systems, and other water facilities. The purchaser is responsible for determining whether any unusual circumstances related to the project require additional provisions that are not included in the standard. Such special conditions might affect design, manufactu

26、re, quality control, corrosion protection, or handling requirements. II.A.2 Testing of special sections. Sec. 5.2.2.1 describes test methods that may be necessary if, in the opinion of the purchaser, unusually severe conditions exist, such as surge or transient pressures that cause stresses exceedin

27、g 75 percent of yield. 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 be stulled to remain round duri

28、ng transportation, installation, and backfilling. 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.
