2、16. ANSI/AWWA C217-16 (Revision of ANSI/AWWA C217-09)ii AWWA Standard This 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 contai

3、ned 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 endorsement of any product or

4、product type, nor does 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 code of any governmental authority. AWWA standards are intended to represent a c

5、onsensus of the water industry that the product described will provide satisfactory ser- vice. 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 ef

6、fective on the 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

7、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 anyone, whether that person has ap - proved the standard or not, from manufacturing, marketing, purchasing, or using products

8、, 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. Producers of goods made in conformity with an American National Standard are encour - aged to state on their own responsibilit

9、y in advertising 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 ANS

10、I 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 no later than five years from the date of publication.

Special Issues. II.A. Advisory Information on Product Application. This standard defines the performance of cold-a

18、pplied petrolatum tape and petroleum wax tape coatings establishing the quality desired for long-term protection and prevention of corrosion. It applies to the exterior coating of steel water pipelines for underground and underwater installation under normal conditions. It is based on previous exper

19、ience but is not designed for unqualified use under all conditions. The advisability of its use for any installation must be reviewed by the purchaser. If an extended period of aboveground storage of coated pipe is anticipated, the materials ability to resist degradation by ultra- violet light and o

20、ther atmospheric and environmental conditions should be considered. 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.

34、and Petrolatum Tape Coating Systems for Steel Water Pipe and Fittings SECTION 1: GENERAL Sec. 1.1 Scope This standard establishes minimum requirements for microcrystalline wax and petrolatum tape coating systems for steel water pipe and fittings. This standard describes exterior coatings that consis

35、t of cold-applied micro- crystalline wax or petrolatum primers and tapes and their applications to special sections, connections, and fittings to be used with buried, submerged, and above- ground steel water pipelines. The primers and tapes are not intended for use with steel joints or sections of s

36、teel pipe where coatings of cement mortar or concrete are applied directly onto the bare steel pipe. These coatings may be field- or shop- applied according to the provisions of this standard. 1.1.1 Conditions not described in this standard. This standard does not describe the additional materials a

37、nd procedures that may be required for difficult conditions, such as those encountered in building some submarine lines, casing pipe, river crossings, and lines that are in rocky areas or in severe soil stress. Consult the manufacturer for the additional materials and procedures that may be required for these conditions. These materials may not be described in this standard.
