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.
