TS tubular heat shrinkable sleeve is designed for corrosion protection of field girth weld joint of buried and exposed steel pipelines, especially for corrosion protection of oil and gas petrol-pipeline. TS is made of a radiation cross linked polyolefin backing, coated with a hot-melting copolymer adhesive which effectively bonds to steel substrates and common pipelines coatings, including polyethylene and fusion bonded epoxy.
TS consists of a unique tubular configuration that has been factory constructed, resulting in quick and reliable field installation. TS can be also easily used for corrosion protection of flange joint, casing and bell joint of steel pipeline.
TS provides excellent resistance to cathodic disbondment resulting in effective long-term corrosion protection.
