Polyethylene oil and gas Cold Applied Tape

Cold Applied Tape, Cold Applied Tapes, Cold Applied Tape Wrap, Cold Applied Tape Coating for Steel Corrosion Resistance..

I. Use and Features:

2-Ply polyethylene (PE) anticorrosive adhesive tape is mainly used for outside anticorrosion project of the buried steel pipelines in petroleum, natural gas, chemicals, urban construction.And it has a widely application in the outside anticorrosion project about overhead metallic conduit. This product has such features as easy construction, no pollution, and therefore is the first choice of outer corrosion protection of pipelines.

This company selects domestically initiated solvent-free co-extruded hot pressing technique to successfully develop high performance PE anticorrosive adhesive tape and its support technique. The backing of product is polyethylene film. The adhesive layer consists of butyl rubber and has excellent anti-aging, sealability insulation effect. In comparison with traditional products made by solvent spreading method, this product has the following features:

(1) Uniform adhesive thickness, and good sealing property.

(2) Big adhesion of base material and adhesive layer, and no degumming during storage or construction.

(3) High thermal-ageing resistance and UV resistance.

(4) High tensile strength and moderate elongation at break, helpful for mechanical and manual winding.

 (5) It has varieties of all kinds, including anti-corrosive tape (Inner tape), protective tape(Outer tape), joint tape, anti-corrosive primer and construction machines and tools, etc.

III. Usage:

(1) Surface treatment of pipeline: Eliminates the rust, welding slag, burrs, oil, dirty and keep clean and dry.

(2) Coating primer: Using special Supporting prime. When used, far away from the fire, mixing well and coating evenly with a clean brush, roller or other mechanical means.

(3) When primer is dry ,it is usually 5-10 minutes(depending on ambient conditions) .Then the tape can be wrapped.

(4) Construction does not begin until this product is stored at about 20°C for 48 hours if it is sharp freeze below -10°C.

(5) The product in all kinds of sizes,we can manufacture according to your demands.

IV. Transport and Storage:

(1) The product is protected from direct sunshine, rain and heavy object during transport.

(2) The product should be stored in the cool warehouse,temperature<75°C and away from heat and fire.
