40 mils joint wrap tape for the welding joints
Highly conformable polyethylene backing with a primer-activated bituminous compound and synthetic resins adhesive offering excellent adhesion properties
Exceptional for coverage of uneven surface joints or welded pipes
Chemical and electrolytic corrosion protection with a non-stick siliconized release film interleaf
Effective as either a pipeline joint wrap or pipeline repair patch
Furnishes a positive-bond to any pipe surface and enduring protection to buried pipelines with Primer
Specialty fittings and fabrication work: a variety of tape systems and mastics that conform to irregularly-shaped pipe.
Field joints: single-sided and double-sided tape systems that conform to bell and spigot, welded and mechanically-coupled field joints.
