anti-corrosion pipeline protective tape(inner wrap)
Product Description
Guanfang 980&955 Coating System For Pipeline
System Description
The Guanfang 980,955 is a multilayer system used for the protection of steel pipelines. Guanfang 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 Guanfang 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer Guanfang 955,achieves a complete bond to the 980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all Guanfang tape systems contain proven anti-microbial additives.The Guanfang 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
