AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifi- cati
4、ons. 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 publication of a standard does not constitute endorsement of any product or product type, nor do
5、es AWWA test, certify, or approve any product. The use 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 wat
6、er supply industry that the product described will provide 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 t
7、he first day of the month following the month of Journal - 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 i
8、s 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 anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes,
9、or procedures not conforming to the standard. Ameri- can 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 advertisi
10、ng and promotional materials or on tags or labels that 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 pro
11、cess. This American National Standard may be revised or withdrawn at any time.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 no later than five years from the date of ANSI approval.

21、eat- Shrinkable Cross-Linked Polyolefin Coatings for the Exterior of Special Sections, Connections, and Fittings for Steel Water Pipelines. However, the compatibility of coating systems is a concern, and the manufacturer of tape described in this standard should be consulted to establish the degree
22、of compatibility with the pipe-coating system involved. ANSI/AWWA C209 defines cold-applied tape coating in terms of its performance or its ability to provide long-term protection and corrosion prevention. This standard is intended for use in the exterior coating of steel water pipelines for undergr
23、ound or underwater installation under normal conditions. This standard is based on the best- known experience, but is not intended for unqualified use under all conditions, and the advisability of its use for any installation must be reviewed by the purchaser. If an extended period of aboveground st
24、orage of coated pipe is anticipated, the ability of the coating to resist degradation by ultraviolet light and other atmospheric and environ- mental conditions should be considered. II.B. Mechanical Protection. When construction or soil conditions exist in which mechanical damage to the coating is l
25、ikely to occur, the use of an extra thickness of tape, suitable overwrap, and reinforcements or special backfills may be required. This will depend on the conditions encountered, but in general, an extra thickness of tape or other wrapping should be used. It should be spiral-wrapped, if possible, an
26、d bonded or mechanically held in place. Under these conditions, the tape manufacturer should be consulted for specific recommendations. II.C. Pipe Storage. Because aboveground and environmental conditions for storage sites vary, the manufacturer should be consulted regarding the type of wrap recomme
27、nded for the specific anticipated storage condition and the necessity for ultraviolet-light protection. II.D. Weld-After-Backfill. Weld-After-Backfill is the sequence of assembling a welded joint, welding the outside joint (if required), applying the exterior coating(s), backfilling the pipe, and th
28、en welding the inside joint at a later time (where internal welding is safe and practical). The interior joint may not be welded until the applied exterior joint coating has been backfilled. Weld-After-Backfill is an acceptable practice provided that the requirements of applicable AWWA standards are
29、 followed. Consult with the manufacturers and other responsible parties regarding recommended products, installation, and backfill procedures required for the Weld-After-Backfill sequence.
