Product Description

Product Description

Huashida introduces its continuous polyurethane (PU) foaming insulation plastic pipe extrusion machinery, meticulously engineered for the efficient and automated production of small-diameter PU insulated pipes. This advanced production line is primarily designed to handle pipe diameters ranging from 48mm to 630mm.

The essence of this equipment lies in its highly integrated manufacturing capability. It innovatively combines multiple crucial processes in insulated pipe production-including outer protection pipe extrusion and insulation material pouring and foaming-to be completed continuously on a single production line.

√ Significantly boosts production efficiency.
√ Primarily manufactures various polyurethane insulation pipes.
√ Ensures a tight bond between the inner pipe, insulation layer, and outer protective layer.
√ High automation effectively reduces manual operations, leading to a substantial improvement in product quality stability.
√ Widely applied in pipeline construction requiring insulation, such as central heating pipelines and oil pipelines.
