Fiberglass pipe wrap tissue is mainly used as base materials for anti-corrosion wrapping on steel pipelines for oil or gas transportation. It is characterized by high tensile strength, good flexibility, uniform thickness, solvent resistance, moisture resistance, non-rotting and flame retardation. It is well compatible with impregnating bitumen and coal tar enamel. The oil or gas pipelines wrapped by S-WT tissue can widely improve capabilities against leakage and aggressive media in the environment so that the cost for maintenance can be minimized significantly. So it is excellent materials for oil or gas pipe wrapped by S-WT tissue.
