HDPE Heat Shrinkable Sleeve Production and Adhesive Coating Line Thickness 1.5-3.5 mm
HDPE Heat Shrinkable Sleeve Production And Adhesive Coating Line Thickness 1.5-3.5 mm
Product Description
The HSSC-1 Heat Shrinkable Sleeve (2-layer) is developed and manufactured by Qingdao Huashida Machinery Co., Ltd for pipeline anti-corrosion applications. This sleeve consists of radiation cross-linked polyethylene backing and high-shear strength melt adhesive, featuring shape memory functionality. The hot melt adhesive is pressed into the joint by the shrink force, forming a perfect seal after heating. The HSSC-1 sleeve is compatible with standard pipe coatings, and is ideal for use with bare pipes, replacement pipe sections, and large-radius bends. It is particularly suited for large-diameter wastewater pipes, requiring minimal preheating during installation.
In addition, we also offer a three-layer reinforced heat shrinkable sleeve, which is composed of three layers of material designed to enhance the sleeve's durability, protective capacity, and anti-corrosion properties. The middle mesh layer is typically a reinforced mesh (subject to customer requirements), and its main function is to enhance the mechanical strength and tensile resistance of the heat shrinkable sleeve.
Buried Pipeline Field Joint Heat Shrinkable Sleeve is made by PE/PP material, used for oil/gas/water pipeline anticorrosion joints. It is served for 3LPE/PP pipeline, pre-insulation pipe end seal, and hdpe corrugated pipe. 
Application fields
Application area:
It is mainly used for wrapping around pipe, anti-corrosion of kinds of pipe joints, and repairing pipes.
For example: Oil and gas pipe, PU insulation pipe, 3PE/2PE steel pipe.

Product introduction
PE backed heat shrinkable wraparound sleeve (HSS) for pipeline is composed of radiation cross-linked polyethylene backing and special heat melt adhesive.
There is also a reinforced type, in which a glass fiber reinforced layer is added to the backing for better effect.
When heating the heat shrink sleeve, the PE backing shrinks and the adhesive melts. The sleeve closely wraps around the pipe. The heat shrinkable sleeve (HSS) forms a firm and continuous anti-corrosion body, which is resistant to corrosion, wear, impact, UV and aging.
Detailed Photos
Application:
1. Field joint corrosion protection for gas oil steel pipeline, water supply pipeline.
2.Corrosion protection pipes, bends, fittings of pipeline.
