pipeline joint wrapping tape
Coating System for Girth Weld Coating, Coating of Fitting, Coating Repair –Joint wrap
T300 series are 2-Ply polyethylene (PE) anticorrosive adhesive tapes. It is Cold wrap tape coating system for Girth Weld Coating, Coating of Fitting, Coating Repair.
In order to promote high adhesion of the coating system to the pipe, the more higher Solid content primer is recommended. More Primer Solid content , providing maximum handling for the coating system with PE tapes.
Structure
FeaturesHeavy duty adhesiveResistant to UVCan be applied over a wide temperature range Good conformability and consistent uniform thicknessEasily applied with no special equipmentConformable to irregular shapes.Meets ASTM D 1000 StandardCold applied
