Outer Tape

Outer Layer Pipe Wrapping Tape

Backing: Polyethylene Basic Material
Adhesive: Butyl-Rubber Basic Adhesive

The T-200 series of outer tape is applied after the inner layer tape by hand or with a wrapping machine. Its usage is to protect the underground or overhead pipeline used for transporting oil, gas, petroleum and waste water from corrosion. The product consists of butyl rubber adhesive layer and the specially blended stabilized polyethylene film backing. The backing can be compounded to resist outdoor weathering. The thickness of the product is 0.5mm. The product with the thickness ranging from 0.38mm to 1.0mm can also be available.

Features
1. The outer layer pipe wrapping tape meets the standard of ASTM D 1000. It is excellent in adhesion to inner-layer tape.
2. The product is resistant to UV light and cathodic disbondment.
3. With good conformability and consistent uniform thickness, it can be applied easily with no need for special equipment.
4. The product can be used in a wide temperature range.
5. The outer tape is applied in cold state and compatible with common pipe coatings.

Polyethylene Drainage Pipeline Anticorrosion Adhesive Tape

1. The multi-layer type anticorrosion system of the product consists of inner-layer anticorrosion tape and outer protective layer resistant to mechanical impact. Completely different from the other anticorrosion coating, it has excellent anticorrosion effect and resistance to impact.
2. The product has wonderful resistance to water and oxidation.
3. The butyl rubber contained in the adhesive layer has superb oxidation resistance function.
4. When wrapping the product, operation with uniform and correct thickness and overlapped width of the product can avoid material waste and reduce cost effectively.
5. Once the steel pipe is wrapped with the polyethylene anticorrosion adhesive tape, the product starts to exert its function immediately. There is no need for curing period. So, the wrapped steel pipe can be lifted and hoisted immediately to shorten the construction time.
6. The product has very low cathodic disbonding rate, high adhesive force to steel pipe, strong resistance to impact and penetration. It is a robust anticorrosion system.
7. It can be applied conveniently with safety and good environmental protection. There is no need for solvent.
8. It can be used for wrapping steel pipe with the diameter of wide range. The smallest value of the diameter can be 50mm and the maximum value can be 1800mm.
9. The applicable temperature range of the product is wide from minus 30℃ to 90℃. The temperature resistance property is stable.
