Guanfang 934/955 Cold Applied Tape Coating System
System Description
Guanfang 934 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 Guanfang 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 Guanfang 934 tape coating system is universally specified in the oil, gas and water industries.
