1. Anticorrosion Tape
Anti-corrosion tape [inner tape]:Polyethene is used as the base material which is coated by the liquid butyl rubber film, both of which are pressed and compounded. It is mainly used on underground, underwater and overhead pipelines. The major function for this tape is for anticorrosion of pipe.

a. Use polyethylene and butyl rubber as main materials, excellent insulation resistance and Iow water absorptivity.
b. Wide range of operation temperature from-30oC to 80oC.
c. Ideal tape anti-corrosion system is a multi-layer system which is composed of inner anti-corrosion tape and outer protective tape resistant to outside mechanic impact. With high anti-corrosion performance and impact resistance.
d. With a long life of over 30years.
e. Widely used on pipes whose sleeve diameters are from 50mm to 1800mm. Convenient construction, safe and clean operation, suitable to factory production and field construction under normal temperatures.
f. Low cost.
2. Protective Tape
Protective tape (outer tape):Polyethene is used as the base material which is coated by the liquid butyl rubber film, both of which are pressed and compounded. The film of protective tape is thicker and higher in intensity. Protective tape will protect the pipe and its anti-corrosion tape surface from damages.

3. Joint Wrap Tape
Joint wrap tape: Polyethene is used as the base material which is coated by the liquid butyl rubber film, both of which are pressed and compounded. Usually its pe film is thinner than the one of anti-corrosion tape while the adhesive layer is much thicker. Joint wrap is used on pipe joints, fabrications, bends, fittings and tie bars.
