Usesing
Provides long-term Corrosion Protection to steel pipelines.
Repair of damaged factory applied corrosion protection.
Outlining weld beads and cut backs prior to wrapping bare-welded joints.
Outlining seams on spiral and seam welded pipe.
Primer-less mastic tape readily conformable to odd-shaped pipe
fittings, valves, flanges and other buried structures.
Application
Prepare surfaces by eradicating all loose scale, rust or other foreign matter
by grit blasting or wire brush. The surface must be clean, dry and free of grease.
Peel back strip and apply tacky side of the tape to the surface and apply pressure.
Apply the tape spirally with sufficient tension to make it conform.
Remove interleaving as wrapping proceeds. Overlap each turn by at least 1” or 55%.
(Note: when proper surface prep is not achievable or when applying to pitted pipe,
apply a thin film of Butyl Pipe Primer to all surfaces to be wrapped and allow to dry).
(Over width silicone paper prevents product contamination during site handling and storage).
