Butyl rubber tape for pipeline protection
I Product Introduction
It is tape-shaped anticorrosion material made of Polyethylene film heat laminated with adhesive layer of butyl glue. The product, safe and clean, performs well in insulation, anticorrosion, mechanical strength and anticollision, moreover it is of low water absorption, long service life, wide usage and convenient in application. 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.
II Characteristics

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
