---2PE insulation pipeline joint coating & mainline coating
HIS-50 Ultra-low temperature Heat Shrinkable wraparound Sleeve is designed 2-layer joint coating for corrosion protection of girth weld joint buried and exposed insulation steel pipes, it is combined with radiation cross-linked high strength super-tough polyethylene backing and special type of rubber adhesive with endure high temperature and ultra-low temperature feature, HIS-50 can be constructed under ambient temperature low to -50°C.
When installing the HIS-50,use propane torch flame simply remove moisture on the surface of insulation layer or outside coating, wrap HIS-50 heat shrinkable sleeve on the insulation pipe, ensure the overlap width is more than 100mm between sleeve and coating. Uniformly heat HIS-50 by torch, the sleeve uniform shrunk on radial direction by heating, at the same time, special adhesive layer melt, uniformly cover and fill the surface of pipeline. After cooling to ambient temperature, cross-linked high strength super-tough polyethylene backing form an outside shield to resist the mechanical damage and moisture immerse, special adhesive layer can form strong physical bonding with PE backing and insulation coating, build a continue ,tight waterproof and anti-corrosion system, it effectively resist soil stress, water pressure, chemical corrosion and mold erosion.
HIS-50 is applied for field girth weld joint coating for insulation pipeline with PE factory coating, the whole insulation pipeline outside coating and outside coating repairing, it can be used one joint overlap another joint to continuously protect the whole pipe.
Construction: Two-layer system
First layer: Endure High & Ultra-low temperature rubber elastic sealant
Second layer: Radiation cross-linked, high strength super tough polyethylene backing with TIP (Temperature Indicator Pattern)
