Pipe
wrap mat
Pipe
wrap mat is used as base material for anti-corrosion wrapping on
steel pipelines that buried underground for oil or gas transportation.
Its characterized by high tensile strength, good flexibility, unfirm
thickness, solvent resistance, moisture resistance, non-rotting
and flame retardation. Its well compatible with impregnating bitumen
or coal tar enamel. The oil or gas pipelines wrapped by pip wrap
mat pre0impregnated 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 may be prolonged up
to 50-60 tears. Authoritative tests have proven that the property
data of mats in Pipe wrap mat series can all meet or surpass the
technical specification stated in SY/T0079, The oil and gas industry
stardard of the People's Republic of China, and meet the requirement
in the specification of AWWA C-203 as well. Theis mat is an ideal
base material as inner wrap or outer wrap impregnated by bitumen
or coal tar enamel.
