POLYKEN # 934
Tape Coating for Pipeline Joints & Fittings
Thick, aggressive adhesive for corrosion
protection
and repair of main line coatings.
System Description
Polyken #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 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.
