If you are looking for China golden supplier and China good supplier white polyken 955 cold applied bitumen anti-corrosion tape, good quality and high quality white polyken 955 cold applied bitumen anti-corrosion tape, please feel free to contact Jining Qiangke Pipe Anticorrosion Materials Co.,Ltd.
System Description
The white polyken 955 cold applied bitumen anti-corrosion tape offers a series of coating systems designed specifically for in-field applications on new construction pipe or reconditioning of existing pipelines. In-field or in-situinstallation is economical and efficient. The reconditioning systems can be applied on existing operating pipelines, which means no loss of revenue and downtime. 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.
