I System description:
Heat Shrinkable Tape is designed to protect the weld joint of buried or exposed steel pipelines and insulated pipeline. This sleeves are manufactured from high quality cross linked polyethylene material. Hot melt adhesive provides excellent adhesion with the surface of steel pipeline, PE coating. Meanwhile it forms a continuous and firm anti-corrosive system with the surface of the pipeline.
The Polyethylene Heat shrinkable Tape needs no primer nor patch closure and reduces application time and labour costs.
â…¡ Structure
The specification of the tape consists of three layers,
Adhesive: butyl rubber based hot melt adhesive
Film backing: Radiation crosslinked polyethylene
Interleaf:Antiadhesive Film Treated with Silicone
â…¢ Features
After heating, formed corrosion protection seal
Strong backing provides outstanding waterproofing effect
High chemical resistance. resists impact, abrasion and ultraviolet light.
Excellent resistance against cathodic disbondment, dielectric breakdown.
Simple Application

â…¤ Application
No Special skills, equipments, patch closure nor primer are needed. Its superior flexibility provides easy and reliable application for irregular configurations of fittings, bends and elbows and small diameter of straight pipes
Wrap spirally the tape over foreign matters-free and preheated surface, beginning at least 25~50mm (1~2 ) onto pipe coating. Wrap the tape with enough tension to obtain conformability and with minimum 50% of overlapping, while removing the release liner. Warm the end part of the tape and press down firmly. Using a torch, start at the edge of the tape and heat circumferentially around the coated pipe.
Finish off by heating over the entire tape vertically to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.
