3、uction or networking permitted without license from IHS -,-,- AVVWA Standard This document is an American Water Works Association (AWWA) standard. It is not a specification. A W A standards describe minimum reqEirements and do not contain all of the engineering and administrative information normall

4、y contained in specifications. The A W A 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 publication of a standard does not constitute endorsement of any prod

5、uct or product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. AWWA standards are intended to represent a consensus of the water supply industry that the product described will provide satisfactory service. When AWWA revises or withdraws th

6、is standard, an official notice of action will be placed on the first page of the classified advertising section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. American National Standard An American

7、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 consumer, and the general public. The existence of an American National Standard does not in any respect preclude an

8、yone, whether that person has approved the standard or not, from manufactur- ing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Prod

9、ucers 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 the goods are produced in conformity with particular American National Standards. CAUTION NOTICE: The American N

10、ational 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 This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard

11、 no later than five years from the date of publication. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute, 11 W. 42nd St., New York, NY 10036; (212) 642-4900.

16、 McGrath, Simpson Gumpertz (2) will not support the growth of bacteria; and (3) will not adversely affect the potable qualities of water. Sec. 4.5 Pipe Dimensions 4.5.1 Diameters. Pipe diameters and tolerances shall be as shown in Tables 1, 2, 3, 4, 5, and 6 when measured in accordance with ASTMD356

17、7. These tables include dimensions for pipe based on both inside and outside diameters. In the latter case, tables are provided for steel-pipe-equivalent ODs, cast-iron (ductile- iron)-pipe-equivalent ODs, and metric ODs commonly used in international practice. *See Sec. I.C. Acceptance in the forew

19、the tables cover nominal pipe sizes 1 in. through 144 in. (25 mm through 3,600 mm); individual tables cover only a portion of the total range. 4.5.2 Length. Pipe shall be provided in standard laying lengths as agreed on by the purchaser and manufacturer. A maximum of 15 percent of the footage of eac

20、h pipe size may be provided in random lengths. Each random length provided shall not vary by more than 25 percent from the standard laying length specified, except for special orders. NOTE: Common practice in the industry provides for laying lengths of 10, 20, 30, 40, or 60 ft (3, 6, 9, 12, and 18 m

21、). Wall thickness. The average wall thickness of the pipe shall not be less than the nominal wall thickness published in the manufacturers literature current at the time of purchase, and the minimum wall thickness at any point shall not be less than 87.5 percent of that nominal wall thickness when m

22、easured in accordance with ASTM D3567. 4.5.3 Sec. 4.6 Pressure Classes The standard pressure classes for pipe shall be 50, 100, 150, 200, and 250 psig (345, 689, 1,034, 1,379, and 1,724 Pa). The pressure classes refer to the maximum sustained working pressure. They are determined in accordance with

23、Sec. 4.6.2 using a design factor of 1.8. The pressure classes may have to be changed for pipes conveying water at elevated temperatures (in accordance with the manufacturers recommendations) and whenever there is a need to provide more allowance for surge pressure. For pipe subjected to circumferent

24、ial bending, the effect of this bending on the hydrostatic design pressure class of the pipe must be considered. 4.6.1 Thermoplastic lined pipe. The pressure classes for thermoplastic lined pipe are based on a water temperature of 73.4“F (23C). The classes may need to be reduced for use at temperatu

25、res greater than 73.4“F (23C). The temperature-derating service factors shall be supplied by the pipe manufacturer.
