Tape Coating Systems for the Exterior of Steel Water Pipelines
|Publication Date:||17 January 2010|
This standard describes the materials and application of tape coating
systems in coating plants at
fixed sites using coating techniques and equipment as recommended by
the tape coating manufacturer.
For normal construction considerations, prefabricated polyolefin tapes
are applied as a three-layer
system consisting of (1) liquid adhesive, (2) corrosion-preventive
Maximum temperatures. All AWWA pipe coating standards are intended for potable-water service; therefore, the maximum service temperature of this coating is based on the maximum service temperature of potable water. These coating systems will perform at higher temperatures. Consult the coating manufacturer for conditions and limitations.
Conditions not described in this standard. This standard does not describe the additional materials and procedures that may be required for difficult conditions, such as those encountered in rocky areas and in construction of underwater lines, casing pipe, and river crossings outside the scope of AWWA C214.
