Computerized Single-screw Heat Shrink Sleeve Production Line with 0.5-3mm Sleeve Thickness for 3lpe Pipeline Joint Closure

eat Shrink Sleeve Machinery 3lpe preinsulated HDPE Pipeline Field shrinkable Joints
 

Radiation cross-linked heat shrinkable sleeves are mainly used for field girth weld coating of 3LPE or thermal insulated pipelines, providing excellent anti-corrosion and waterproof protection for pipe joints, especially in plastic water supply and drainage systems.

The Huashida Brand Heat Shrinkable Sleeve Extrusion Line adopts a complete and advanced production process.
Step 1: The PE backing film extrusion line produces PE film according to customer requirements.
Step 2: The PE film is then sent to a professional irradiation facility for radiation cross-linking treatment, which enhances the film's fire resistance, tensile strength, and thermal stability.
Step 3: The irradiated film is transferred to the heat shrinkable sleeve adhesive coating line. In this stage, the film substrate is stretched twice to ensure an optimal shrink ratio. A specially formulated hot-melt adhesive is prepared in a professional reactor, extruded, and uniformly bonded with the cross-linked PE backing film.

The final product features high adhesion strength, excellent corrosion resistance, and stable shrink performance, meeting international standards for pipeline protection.
