Product Overview

The One-Step Spray Winding Production Line is an advanced solution specifically engineered for the continuous manufacturing of large-scale pre-insulated pipes. Utilizing a high-load screw conveyor system, the line integrates polyurethane (PU) foam spraying and polyethylene (PE) winding into a single, seamless process.

This innovative technology overcomes the common limitations of traditional batch production—such as low efficiency and poor foaming quality—and surpasses existing continuous lines by offering superior load-bearing capacity for ultra-large pipe diameters. It provides the insulation pipe industry with a highly intelligent, integrated solution that significantly boosts productivity while reducing raw material waste and energy consumption.
