How much you know about oil gas pipeline polyethylene anticorrosion tape? Polyethylene anticorrosion tape unwound when the temperature must be above 5 ℃, corrosion layer construction should be carried out at -5 ℃ above. (Experience has shown that tapes can be at a lower temperature -30 ℃ when the construction, but to ensure unwinding temperature) when the ambient temperature is below 10 ℃, in order to ensure real-time tape has good adhesive strength, should adopt blowtorch heat pipe dimensions and baking adhesive tape

Oil pipeline tape ,gas pipe WRAPPING TAPE & PRIMER APPLICATIONS:
Rust Removal > Priming> Inner Tape & Outer Tape Wrapping
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.
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.
