Detailed Product Description

pre-insulated plastic pipe production line is a specialized production line used to manufacture insulated plastic pipes, commonly used in district heating, hot water supply, and industrial applications. These pipes typically consist of an inner plastic pipe (often PEX, PP-R), an insulating layer (usually polyurethane foam or another thermal insulator), and an outer protective casing (often HDPE or another durable plastic).


ComponentDescriptionKey Sub-Parts
Inner Pipe Extrusion LineProduces the inner plastic pipe (PEX, PP-R, PB, etc.).- Extruder
