Protection Tape Protective Tape Anti-corrosion Tapes for Steel Pipe Surface Corrosion Protection

Specifications Protection Tape Protective Tape for Underground Steel Pipe Surface Corrosion Protection & Anti corrosion Coating

1. INTRODUCTION TO PRODUCTS:   Outer Tape ( Protection Tape Protective Tape for Steel Pipe Surface Protection ) Systems Description: The Outer Tape T-200 series is cold applied Protection Tapes coating systems for Protection of the pipe and its T-100 Series surface from damages. Butyl Rubber Adhesive 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.   Product Advantages: Conformable to irregular shapes. No release liner. Established in ground history. Complies with AWWA (American Water Works Association) C-214 standard. Compatible with general coating systems   T-200 Outer Tape ( Surface Protection Adhesive Tape ) series Coating Systems with AWWA C-214 Standard:

  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.   3.
