1.2mm Thick and 50mm width  PE  Bitumen Tape for Oil Gas Water Pipeline Corrosion Protection

Self adhesive bitumen tape system description:

The Self adhesive bitumen tape is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, Waste Water underground or overhead pipelines and waterproofing.

The Self adhesive bitumen tape shall be applied after the primer by hand or with a wrapping machine

Self adhesive bitumen tape structure

The specification of the tape consists of three layers,

Adhesive: Butyl rubber Bituminous Compound and Adhesion Promoting Resins

Film backing: Special blend of stabilized polyolefines

Interleaf: Antiadhesive Film Treated with Silicone

Self adhesive bitumen tape features:

Heavy duty butyl bitumen compound adhesive

Excellent adhesion to pipe and self

Flexibility provides extra protection at vulnerable areas

Excellent conformability and consistent uniform thickness

Easily applied with no special equipment

Compatible with common pipe coatings

Excellent resistance to cathodic disbonding

Resistant to UV

Can be applied over a wide temperature range

Good conformability and consistent uniform thickness           

Cold applied
