HWT heat shrinkable wraparound tape is designed for corrosion protection of field girth weld joint of buried and exposed steel pipelines, also for pipe bends or pipe elbow. HWT consists of a radiation crosslinked low density polyethylene backing, coated with a hot sensitive adhesive which effectively bonds to steel substrates and common pipelines coatings, including polyethylene and fusion bonded epoxy. HWT can be conveniently used for corrosion protection of steel pipe, especially for protection and repairing pipelines, fittings, elbows, bends and other irregular configurations.
HWT provides excellent resistance to cathodic disbandment resulting in effective long-term corrosion protection. The high performance crosslinked backing in combination with a broad of adhesive can be undertaken for regular or high stress environments. Upon the application of heat, wrap around tape shrinks down to fully encapsulate the protected substrate, the hot melting adhesive flows into all surface irregularities, forming a protective barrier against corrosion.
