34、 is not a part of ANSI*/AWWA C225. I. Introduction. I.A. Background. This standard describes the minimum material and application requirements for a fused polyolefin coating system to be plant-applied to the exterior of steel water pipe for purposes of underground corrosion protection. Currently, th
35、e only fused-type coatings for which significant performance experience in this application has been accumulated are based on polyolefin. I.B. History. The fused polyolefin coating system has been in existence since approximately 1988. Steel Pipe New Zealand has been applying this system to large- d
36、iameter water pipe since 1994. With the exception of a few water pipe projects around the world, the remainder of the history of this system has been in the oil and gas industry. The first edition of ANSI/AWWA C225 was approved by the AWWA Board of Directors on Jan. 19, 2003. The second edition was
37、approved on June 24, 2007 . This edition was approved on Jan. 19, 2014. I.C. Acceptance. This standard has no applicable information for this section. II. Special Issues. There are no special issues described in this standard. III. Use of This Standard. It is the responsibility of the user of an AWW
38、A 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 items should be specified by the purchaser: 1. Standard usedthat is, ANSI/AWWA C225, Fused Polyolefin Coa
39、tings for Steel Water Pipe, of latest edition. 2. Any exceptions to the standard that may be required. 3. Diameter, length, and location of pipeline. 4. Location of coating application with reference to environmental considerations. 5. Maximum internal operating temperature of the pipeline (Sec. 1.1
40、.1). 6. Requirements for outdoor storage (Sec. 4.3.2.4). 7. Requirements for ultraviolet-light protection (Sec. 4.3.2.4). 8. Requirements for coating system thickness (Tables 2, 3, and 5). * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Copyright 2014

Major Revisions. Revisions made to this standard in this edition include the following: 1. The title of the standar
45、d was changed to be consistent with other AWWA steel pipe coating standards. 2. Requirements were divided into prequalification requirements and quality control requirements. Related changes were made to the titles of Tables 25. 3. Removed maximum thickness requirements in Table 2, 3, and 5. 4. Remo
46、ved minimum value for nonpolyolefinic material in Table 2. 5. Changed Dielectric Strength in Table 2, 3, and 4 to 450 V/mil (was 900 V/mil and it was incorrect). 6. Added Cathodic Disbondment to Table 4. The maximum radius is 12 mm when tested per ASTM G8. 7. Table 5 was created to list quality cont
47、rol properties for the coated pipe. 8. Adhesion testing of tape was moved from the prequalification tables to Table 5 for quality control requirements. 9. All existing wording in Sec. 4.5, Field Procedures, was removed. The section now references AWWA C604. Copyright 2014 American Water Works Associ
48、ation. All Rights Reserved. xi 10. Section 5, Verification, was updated to match the new language being used in all coating standards. 11. Test method 5.5.3 was created to detail the peel adhesion test method of a coated pipe and add language to address rejection of pipe. 12. Frequency of adhesion t
49、esting was added to Sec. 5.5.3. 13. Sec. 5.5.4 was added to address adhesion testing of the outer layer tape. V. Comments.
