Heat shrinkable sleeve for oil-gas pipeline
Heat shrinkable sleeve , which is developed and manufactured by Qingdao Huashida machinery Co., Ltd for anti-corrosion of pipeline. The hot melt adhesive is squeezed into the joint by the shrink power to form a perfectly sealed surface, after being heated. HSSC-1 is compatible with standard pipe coating, also can be used for coating bare, replacement pipe section and large redius.
Why does the Heat shrinkable sleeve of "Huashida" have the better adhesion for anti-corrision pipe （3PE）？ First let us introduce for you the Construction of anti-corrision pipe （3PE).
layer system (3PE):
- First layer: Liquid epoxy.
- Second layer: Heat melt adhesive.
- Third layer: Radiation cross-linked, high density polyethylene film.
This system is a wrap-around heat shrinkable sleeve which replicates the structure and performance of mill-applied three-layer PE coatings.
During installation, the epoxy is applied to the prepared pipe surface and the heat shrinkable sleeve is immediately wrap around the joint over the wet epoxy. Heat is then applied to the sleeve which shrinks to form a tight fit around the joint. While curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface & to the copolymer adhesive layer. The radiation cross linked outer layer forms a tough barrier against mechanical damage and moisture transmission.
Reamark: The thickness mainly according to the buyer’s requirements.
