The HDPE Heat Shrinkable Sleeve Production Line (Basic Layer) is a specialized manufacturing system designed for producing non-crosslinked and non-irradiated HDPE heat shrinkable sleeve base materials. This line manufactures high-quality HDPE sheets or sleeve substrates that serve as the foundation layer for heat shrinkable sleeve products used in pipeline anti-corrosion and protection applications.
Featuring advanced extrusion technology, stable output performance, and precise thickness control, this production line ensures consistent product quality while reducing production costs. It is engineered to manufacture the primary HDPE backing layer used in heat shrinkable sleeve systems for pipeline joint protection, offering a simpler and more economical production solution.
Primarily used for pipe connection, field joint coating, wrapping around pipes, anti-corrosion of various pipe joints, and pipe repair applications. Suitable for oil and gas pipes, PU insulation pipes, 3LPE/2LPE steel pipes, and corrugated pipes.
