anti corrosion tape for steel pipe
1. INTRODUCTION TO PRODUCTS:
Inner Tape ( Anti corrosion Tape Anticorrosion Tape Anti corrosive Tape for Steel Pipe Anti corrosion Coating ) System
Description:
The T-100 series is Cold Applied Anti-corrosion Tape Coating Systems for the anticorrosion /
anti corrosion of underground, underwater, and overhead pipelines. Butyl Rubber Adhesive
of Anticorrosion Tape 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.
2. POLYETHYLENE PE TAPE & PRIMER APPLICATIONS:
Rust Removal > Priming> Inner Tape & Outer Tape Wrapping
2.1 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.
2.2 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.
2.3 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.
