Product Description
FOREVER wraparound heat shrinkable sleeve (HSS)
FOREVER wraparound heat shrinkable sleeve with a separate closure patch is mainly used for field joint coating of underground 3LPE coated steel pipelines and thermal insulated pipelines.
FOREVER wraparound HSS bonds the steel substrate, primer and plant-applied polyethylene coatings excellently to form a continuous and durable corrosion protection system on the pipeline
The shrink sleeve system consists of a two-component solvent-free epoxy primer, a wraparound heat shrinkable sleeve and a closure patch.
Product Description
Heat shrink sleeves for three layer pipelines
Description :
Heat shrink sleeves for three layer pipelines- heat shrink wrapping
coating consist of cross linked polyethylene backing, hot melt and primer. The three layer pipeline applicated Heat shrink sleeve is compatible with and made from similar materials as Pre–manufactured Three Layers anticorrosion tape.
Heat shrink sleeves mainly used in coating the weld joint of buried steel pipeline, Elbow, Tee joints ect.
The steel substrate, FBE primer and plant-applied polyethylene coatings excellently to form a continuous and durable anti-corrosion system on the pipeline.
Heat shrink sleeves for three layer pipelines Features:
Excellent adhesion to steel pipe
Long term corrosion protection , Resistant to UV
High chemical resistance under service temperature.
Outstanding electric property and permanent adhesion.
Perfect abrasion resistance performance
Note:
1) Closure patch length and thickness are equal to sleeve axial length and thickness, respectively.
Closure patch width:
100 mm for pipe diameter Φ168 ～Φ355
150 mm for pipe > Φ355.
2) Custom-made is available to meet any customer special demand.
