One-Step Coutinued Polyurethane Preinsulated Pipe Production Line (Dia 32-426mm)
One-step Polyurethane Preinsulated Pipe Production Line (Dia 32-426mm)
The one-step polyurethane insulation pipe production line of Huashida produces small-diameter polyurethane insulation pipes with an outer diameter ranging from Φ32 to Φ426mm.
The main feature of this equipment is that multiple processes of the insulation pipe, such as extruding the outer protective pipe and injecting insulation materials, are continuously completed on the same production line, resulting in a relatively high production efficiency. It is mainly used for manufacturing polyurethane insulation pipes, etc., which can closely combine the inner pipe, insulation layer and outer protective layer of the insulation pipe. Its degree of automation can effectively reduce manual operation links and improve the stability of product quality.
The whole production line is composed of:
Extruder → Die head → cooling water tank → Traction machine → Cutting machine → pipe clamping machine → Bracket and electrical control
Application scenario:
It is widely used in heat supply pipeline, oil transmission pipeline and other pipelines that need heat preservation.
