Single side butyl rubber wrap tape anti corrosion for gas pipe Outer Wrapping Tape The XUNDAT200 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines. The outerlayer tape backing shall be compounded so that it will be resistance to outdoor weathering.The outer-layer tape shall be applied after the inner-layer tape by hand or with a wrapping machineCorrosion 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. Usage and Features: 1. Widely used on underground and overhead pipelines anticorrosion protection system. 2. Excellent adhesion to pipe and self 3. Resistant to UV 4. Can be applied over a wide temperature range from-30°C to 80°C 5. Good conformability and consistent uniform thickness 6. Cold applied ,and easily applied with no special equipment 7. Compatible with common pipe coatings 8. Excellent resistance to cathodic disbonding 9. Meets ASTM D 1000 Standard 10. Long term corrosion protection and mechanical resistance The tape consists of two layers, adhesive and film Inner layer: butyl rubber Outer layer: polyethylene Thickness: 0.35 - 1.30mm Width: 50-300mm Length: 30 - 200m 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 PrimingPrimer 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.
