Polypropylene fiber corrosion tape is a new non-polluting, non-hazardous environmentally friendly anti-corrosion material, the substrate is a unique modified polypropylene woven fabric used to make butyl rubber modified asphalt corrosion layer, its base fibrous structure can effectively resist the creep stress generated due to soil damage, the aging test to detect corrosion proof lifetime of more than 50 years. Cold pipeline corrosion construction tape the best choice, but also the most economical choice preservative. It can be widely used in petroleum, natural gas, chemicals, urban construction, water supply and drainage, gas, gas transmission pipelines and steel underground steel storage tank external corrosion and repair works.

Usage:

(1)steel surface treatment: rust, welding slag, burrs, oil, dirt and kept clean and dry. Hand rust should reach St3 level, mechanical descaling should reach Sa2 level.
(2)primer: primer should be used for supporting, away from the fire source, and stir with a clean brush, roller or other mechanical methods applied uniformly. Primer Dosage: manual coating 12㎡ / L mechanical applicator 20 square meters / L.
(3)until the primer is dry (usually 5-10 minutes) can be wrapped around the belt.
(4)under the trench backfill: acceptance by the quality inspection to the next ditch.
(5)tapes during transport anti-exposure, rain, prevent crushing distortion.
(6)in transport or storage subject to the following 5 ℃ during storms and cold, should be stored at about 20 ℃ 48 hours before construction.
(7)it should be in a cool, temperature 5 ~ 30 ℃, temperature <75 ℃ warehouse storage, storage period of 12 months, and away from heat and open flame.
