Fibreglass Surfacing Mat
Product type: C-PM MAT(pipe wrap surfacing mat)
 1. COMPOSITION AND PRESENTATION
Pipe wrap surfacing mat is used as base material for anti-corrosion wrapping on steel pipelines that buried underground for oil or gas transportation. The oil or gas pipelines wrapped by C-PM mat pre-impregnated with bitumen or coal tar enamel acquire excellent capabilities against leakage and aggressive media in the environment so that the cost for maintenance and replacement can be minimized significantly and the life time of pipeline maybe prolonged up to 50-60 years. Authoritative tests have proven that the property data of mats in C-PM series can all meet or surpass the technical specification stated in SY/T0079, the oil and gas industry standard of the people’s republic of china, and meet the requirement in the specification of AWWA C-203 as well.
2. PROPERTIES & APPLICATION
Properties:
Well compatible with impregnating bitumen or coal tar enamel, Non-rotting and flame retardation, High tensile strength, Uniform thickness, Solvent resistance, Moisure resistance, Good flexibility.
Application :
This mat is an ideal base material as inner wrap or outer wrap impregnated by bitumen or coal tar enamel.
