asphalt adhesive tape

Features

Excellent adhesion to a wide range of substrates found, including concrete and steel piping.

Compatible with common pipe coatings.

Endures extremes of heat and cold.

Excellent resistance to cathodic disbondment.

High water and vapour impermeability.

 

Uses

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). 

 

Recommended Temperatures

Application Temperature:from +5ºC to +50ºCContinuous Temperature:from –30ºC to +60ºCPeak Temperature:up to +70ºC 

Precautions

Should not be used in applications subject to excessive movements.

PE tape is -shaped anticorrosion material made of Polyethylene film heat laminated with adhesive layer of butyl glue. Cold applied tape coating systems for anticorrosion of field joints, fittings, and specifically piping. The Adhesive is a key in ground performance characteristic coupled with the low and high density polyethylene backing. This kind of tape can be applied by hand or with a wrapping machine.
