Coating system:

The pre-fabricated polyolefin tape coating system shall consist of the following layers to provide an applied coating system thickness of 80 mils (2mm) on the exterior of the steel pipes.

 

  1. A liquid adhesive layer.
  2. An inner-layer tape for corrosion protection.
  3. An intermediate-layer tape for mechanical protection.
  4. An outer-layer tape for mechanical and UV protection.
Liquid Adhesive layer:

 

The liquid adhesive layer shall consist of a mixture of suitable rubber and synthetic compounds and solvent. The liquid adhesive layer shall be spray applied to the abrasive blasted prepared pipe surface before application of the inner-layer tape. The function of the liquid adhesive is to provide a bonding medium between the pipe surface and the inner-layer tape.

 

The liquid adhesive shall be supplied by the manufacturer that supplies the inner-layer tape. 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 machine-application properties.

Non flammable - 10 – 12 lb/gal (1.20 – 1.44 kg/l) none

 

 

 

Inner-layer tape:

 

The inner-layer tape shall be a two-layer tape consisting of a polyolefin backing layer with a laminated butyl-based adhesive layer. The inner tape shall be compatible with the liquid adhesive. The manufacturer shall certify that the backing material shall be polyolefin only, containing not more than 3.5 percent, by weight, of non-polyolefinic material consisting of carbon black and antioxidants. The inner-layer tape shall be applied after the liquid adhesive and before the outer-layer tape.

 

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 primed steel surface. The inner-layer tape shall be of material that will resist excessive mechanical damage during normal application operations 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 inner-layer tape shall be supplied in roll form wound on hollow cores with a minimum inside diameter of 75mm.

 

To ensure a proper smooth coating, the inner-layer tape shall be provided in standard widths as per manufacturer recommendations consistent with the pipe diameter. Width shall be approved by Employer’s representative.

Intermediate- layer tape / Outer-layer tape:

The intermediate -layer tape / outer-layer tape shall be a two-layer tape consisting of a polyolefin backing layer with a laminated butyl adhesive layer. The manufacturer shall certify that the backing material shall be polyolefin only containing not more than 7.0 percent, by weight, of non-polyolefinic material consisting of pigments, antioxidants and stabilizers. The intermediate -layer shall be compatible with the inner-layer tape and the outer-layer tape shall be compatible with the intermediate-layer tape. The primary function of the intermediate - layer tape is to provide mechanical protection to the inner-layer tape and of outer-layer tape to provide mechanical and outdoor weathering (UV) protection to the tape system, and secondarily, to contribute to the overall corrosion-protection properties of the system. The outer-layer tape backing shall be compounded so that it will be resistant to outdoor weathering. To distinguish the intermediate- layer tape from outer-layer tape the colors of the two layers shall be different. The intermediate- layer tape color shall be grey and the outer-layer tape color shall be white.

 

The outer-layer tape should be of suitable quality for the local environment, as follows:

 

Storage Temperature : 0 to 500C.
Over-ground Condition : 0 to 600C.
Under-ground Condition : 70C to 350C.
Ultraviolet-ray Protection : Required in outer layer.

 

Materials used in the intermediate-layer & outer-layer tape shall have high electrical resistivity, low moisture absorption and permeability, and shall provide mechanical protection during handling and outdoor storage. The intermediate - layer & outer-layer tapes shall be sufficiently pliable for normal application operations and shall form an effective bond to the inner-layer / intermediate-tape layers. The intermediate- layer & outer-layer tape shall be supplied in roll form wound on hollow cores with a minimum inside diameter of 75mm.
