110mm-630mm PE Casing PU Foam Pre-Insulated Pipe Making Machine for district heating pipeline
Polyurethane preinsulated pipe is a kind of high-efficiency insulation pipe, which is mainly composed of working steel pipe, polyurethane insulation layer, plastic outer protective pipe and other parts. The working steel pipe is the innermost layer, which is responsible for the function of conveying medium (such as hot water, steam, etc.); the middle is the polyurethane insulation layer, which plays an excellent role in heat insulation and can effectively reduce heat loss; the outermost layer is the plastic outer protective pipe, which is usually made of high-density polyethylene and other materials, which can protect the insulation layer from external environmental erosion and make the appearance of the pipe more regular.
Production line parameters:
(1) Steel pipe coverage: 32mm-530mm
(2) Materials used: black material (isocyanate), white material (combined polyether), polyethylene
(3) Main equipment: extruder, die head mold, vacuum sizing box, traction machine, cooling device, cutting equipment, polyurethane foaming system, pipe wearing machine, heating oven, etc.
