Sell Black pipe wrap tape
Description

Black pipe wrap tape is a synthetic rubber-based material extruded into a soft permanently elastic strip, available in a roll form. The tape possesses high levels of surface tack and performs at a wide range of temperatures.

Structure

Black pipe wrap tape specification of the tape consists of two layers, adhesive layer and film backing

Adhesive: butyl rubber

Film backing: Black Special blend of stabilized polyethylene

Features

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

Effortlessly applied with no special equipment (mouldable by hand).

Compatible with common pipe coatings.

Endures extremes of heat and cold.

Excellent resistance to cathodic disbondment.

High water and vapour impermeability.

 Black pipe wrap tape 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.

Primerless 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 Black pipe wrap 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 +50ºC
Continuous Temperature: from 30ºC to +60ºC
Peak Temperature: up to +70ºC

Precautions Should not be used in applications subject to excessive movements
