pipe coating materials polyethylene wrap black inner tape

详情

pipe coating materials polyethylene wrap black inner tape  is with a

stabilized polyethylene carrier film, coated on one sides with a permanently

plastic synthetic compound on a butyl rubber base. The highly stable

and supple carrier film guarantees a high degree of

protection from mechanical damage.

 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.

The specification of the tape consists of two layers, adhesive layer and film backing

Adhesive: butyl rubber

 Film backing: Special blend of stabilized polyethylene 

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).
