Product Description

Open Cut Polypropylene Three-Layer Heat Shrink Sleeve is a specialized protective coating system used primarily for the repair and protection of pipelines, especially in underground or buried environments. It is commonly used during open-cut pipeline construction or rehabilitation projects where sections of pipe are exposed and require re-coating or sealing.

Here’s a detailed breakdown of what this product entails:

A three-layer heat shrink sleevemade from polypropylene (PP)—a thermoplastic polymer known for its durability, chemical resistance, and excellent mechanical properties. The open cut designation means it's designed for use when the pipeline is already exposed
