If you are looking for China golden supplier and China good supplier polyken underground pipe wrap tape, good quality and high quality polyken underground pipe wrap tape, please feel free to contact Jining Qiangke Pipe Anticorrosion Materials Co.,Ltd.
System Description
The 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. The POLYKEN 980 Polyethylene anti corrosion adhesive tape can be used extensively in metal pipes of all pipelines and facilities in petroleum, natural gas, petrochemical industry, electric power, metallurgy, urban gas pipeline network and water supply etc. For efficient and long lasting outer anti corrosion. Beside, it is also used in buried or overhead metal pipes
