Product Description
The Pipe Coating Tape is a multilayer system used for the protection of steel pipelines. Liquid Adhesives can be used as primers for this system. In addition to
serving as primers, these liquid adhesives themselves represent an anticorrosion layer and provide a uniformly smooth contact surface to promote high adhesion of the coating system to the pipe. They are designed for machine or brush application and formulated with stress-corrosion cracking inhibitors. The Anti-Corrosion layer Corrosion Protection Tape is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer outer tape achieves a complete bond to the Inner Wrap Tape inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all Outer Wrap Tape systems contain proven anti-microbial additives. The Insulation Adhesive Tape can also be used for ductile iron pipes, in this case the use of primer is recommended.
Gas/ oil/water pipe tape inclusing two layes,
1. Adhesive: Inner layer of Butyl rubber.
2. Backing: Outer layer of Polyethylene (PE) Plastic.
