3LPE Preinsulated HDPE Pipeline Field Shrinkable Product Description
Product Overview
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.
