Thick, aggressive adhesive for corrosion protection and repair of main line coatings.
System Description
anticorrosion black polyken 934 butyl rubber pipe wrapping tape is a cold applied tape coating system designed for the corrosion protection of field joints, fittings, and specialty piping. The highly conformable backing and thick, aggressive adhesive also make it the ideal repair system for all types of main line coatings. The POLYKEN 934 tape with very tacky adhesive has a release plastic liner to enable proper unwinding of the roll. Whether used as a double wrap system or as a single wrap with a mechanical layer, the POLYKEN 934 tape coating system is universally specified in the oil, gas and water industries.Polyethylene anti corrosion adhesive tape can be used extensively in metal pipes of all pipelines and facilities in petroleum, natural gas, petrochemical industry, electric power, metallurgy, urban gas pipeline network and water supply etc. For efficient and long lasting outer anti corrosion. Beside, it is also used in buried or overhead metal pipes
