System Description
The polyken955 polyethylene pipeline tape using for steel pipeline is used for steel pipe for surface corrosion protection tape. Cold Applied Tape for pipeline coating is suitable to any diameters for petroleum, natural gas, water supply, city gas, oil and electric power industries etc. the systems are inner wrap tape and outer wrap tape, primer and Putty. POLYKEN 980,955 is a multilayer system used for the protection of steel pipelines. POLYKEN 1019,1027, Liquid Adhesives can be used as primers for this system.In addition to serving as primers, these liquidadhesives 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 POLYKEN 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer POLYKEN 955,achieves a complete bond to the POLYKEN 980 inner layer, providing maximum handling and in-service protection for the coating system. The Middle and Outer Mechanical Protection Layers provide exceptional handling and in-service protection of the coating system.
