Polyolefin Cold applied Tapes as per AWWA C214 standard for water pipes
For normal construction considerations, prefabri-cated polyolefin tapes are applied as a
three-layer system consisting of (1) liquid adhesive, (2) corrosion-preventive tape (inner layer), and (3) mechanical-protective
tape (outer layer). This standard establishes the minimum requirements for tape
coating systems used on the exterior of steel water pipelines in the potable-water
This standard tape is Machine applied tape coating to straight pipe for buried service. The multi-layer coating system is comprised of a butyl rubber adhesive, 20 mil polyethylene tape inner wrap, and one or two 30 mil polyethylene outer wraps. Can be applied to 2" thru 144" diameters.
The liquid adhesive shall be supplied by the
manufacturer that supplies the inner-layer tape. The liquid adhesive shall comply
with code and regulatory requirements in effect at the point of application. The
liquid adhesive shall not settle in the container forming a cake or sludge that
cannot be easily mixed by hand or mechanical agitation, and it shall have good
Inner-layer tape. The manufacturer shall certify that the backing
material shall be polyolefin only, containing not less than 1.0 percent nor more than3.5 percent, by weight, of nonpolyolefinic material consisting of carbon black and antioxidants. The backing and adhesive shall be made from materials that provide high electrical resistivity, resistance to corrosive environments, low moisture absorption and permeability, and shall provide an effective bond to a properly prepared steel surface. The inner-layer tape shall be of material that will resist excessive mechanical damage during normal application operations as outlined in Sec. 220.127.116.11 and shall be sufficiently pliable for the intended use. The inner-layer tape shall withstand, without tearing, the tensile force necessary to obtain a tightly wrapped inner coating free of voids. The properties of the inner-layer tape shall conform to the appropriate values stated in Table 2.
The inner-layer tape shall be supplied in roll form wound on hollow
cores with a minimum inside diameter of 3 in. (75 mm).
18.104.22.168.2 To ensure a proper smooth coating, the inner-layer tape shall be
provided in standard widths consistent with the pipe diameter. Unless otherwise
specified by the purchaser, dimensions of inner-layer tape and outer-layer tape shall
be as stated in Table 5.
Outer-layer tape. The manufacturer shall certify that the backing
material shall be polyolefin only, containing not less than 3.0 percent nor more than 7.0 percent, by weight, of nonpolyolefinic material consisting of pigments, antioxi-
dants, and stabilizers. Materials used in the outer-layer tape provide some electrical
resistivity, low moisture absorption and permeability, and resistance to corrosive
environments. Materials used shall provide mechanical protection during handling
and outdoor storage. The outer-layer tape shall be sufficiently pliable for normal
application operations as outlined in Sec. 22.214.171.124 and shall form an effective bond to the inner-layer tape.
