HDPE Outer Protection Pipe tape
Product Description
HDPE Outer Protection Pipe Tape
Composition:
It is tape-shaped anticorrosion material made of Polyethylene film heat laminated with Adhesive layer of butyl glue.
Usage:
It is extensively used in the pipework of oil and natural gas transportation, petrochemical industry, electric power, metallurgy, urban natural gas network of pipes, the outside anticorrosion project of the metal pipes involved as well as the outside anticorrosion project of the underground and overhead metallic conduit of the works of petrochemical industry, natural gas and coal transportation
Application:
Prepare surfaces by removing all loose scale, rust or other foreign matter by grit blasting or wire brush. Surface must be clean, dry and free of grease. Apply thin film of Butyl Primer to all surfaces to be wrapped and allow to dry. Peel back interleaving and apply adhesive side of the tape to the surface and press down. Apply the tape spirally with enough tension to make it conform. Remove interleaving as wrapping proceeds. Overlap each turn by at least 1" or 55% to achieve double thickness.
Irregular surfaces such as valves, flanges, etc.
.
Corrosion protection tape for metal pipeline is polyethylene cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines.

Application
1 Rust Removal
Steel Surface needs treating. Its quality shall reach Sa2 or St3 grade as prescribed in GB8923-88 Pre-paint Steel Surface Rust Grade and Rust-removal Grade, and it shall be dust-free.
2 Priming
Primer shall be stirred well before painting. An even film of primer is painted on the steel surface that is rust-removed completely and dust-free. After the primer dries up (one may feel no sticky). The steel pipe can be wrapping with tape (it usually takes 3 to 5 minutes). The primer dosage usually amounts to 80 to 100g / m².
3 Inner Tape (Anti corrosion Tape) & Outer Tape (Protection Tape) Wrapping
The steel pipe that is painted with primer is wrapping with tape by means of suitable devices or tools as per joint needs, and wraps the inner tape and then wraps the outer tape. Tape tensibility can be 10 to 20 N / cm. The overlapped length between beginning and end of an adhesive tape shall be no less than 1/4 circumference of the steel pipe and the total length of adhesive tape shall be no less than 100mm. each film shall be paralleled, and must not be twisted and rumpled.
