Polyethylene Pipelines Cold Applied Tape Composition: It is tape-shaped anticorrosion material made of Polyethylene film heat laminated with adhesive layer of butyl glue. Usage: It is extensively used in the pipework of oil and natural gas transportation, petrochemical industry, electric power, metallurgy, urban natural gas network of pipes, the outside anticorrosion project of the metal pipes involved as well as the outside anticorrosion project of the underground and overhead metallic conduit of the works of petrochemical industry, natural gas and coal transportation Thickness: 0.30 - 1.30mm Width: 50, 75, 100, 150, 230, 300mm Length: 30 - 200m Features: Excellent adhesion to pipe and self Resistant to UV Can be applied over a wide temperature range Good conformability and consistent uniform thickness Easily applied with no special equipment Compatible with common pipe coatings Excellent resistance to cathodic disbonding Meets ASTM D 1000 Standard Cold applied Application: Prepare surfaces by removing all loose scale, rust or other foreign matter by grit blasting or wire brush. Surface must be clean, dry and free of grease. Apply thin film of Butyl Primer to all surfaces to be wrapped and allow to dry. Peel back interleaving and apply adhesive side of the tape to the surface and press down. Apply the tape spirally with enough tension to make it conform. Remove interleaving as wrapping proceeds. Overlap each turn by at least 1" or 55% to achieve double thickness. Irregular surfaces such as valves, flanges, etc. packing in carton
