Product description
Polyurethane spraying polyethylene wrapping pre-insulated pipe production line is used for the production of polyurethane prefabricated direct buried thermal insulating pipes, which are widely used in the field of heating, cooling and crude oil transportation.
Pipe structure
Rigid polyurethane spraying polyethylene winding prefabricated directly buried insulation pipe consists of steel working pipe, spraying polyurethane rigid foam insulation layer and winding polyethylene outer protective pipe. See the following figure for product structure
Technological flow:
Upload pipes→pipes conveyor→rust removal→intermediate frequency heating→Epoxy powder coating→Middle layer &polyethylene stripe winding→water cooling→pipes conveyor→ pipe chamfer→unload pipes

Features of the polyurethane spraying PE winding insulation pipe
(1). Density, thermal conductivity, compressive strength and other indices of the polyurethane insulation layer are uniform and consistent. Therefore overall performance of the pipe is superior.
(2). The polyurethane insulation layer is formed by free foaming. Since polyurethane is foamed perpendicular to the axial direction of the pipe, compressive strength of the insulation layer is improved.
(3). The polyurethane insulation layer is formed after spraying. The raw materials are sprayed onto the outer surface of the steel pipe in a liquid form, and then begins to foam. Due to the high reaction activity of the spraying polyurethane raw materials, adhesion between steel pipe surface and polyurethane foam layer is stronger.
(4).Roughness of the surface of polyurethane foam layer is more conducive to increase bonding effect between insulation layer and outer HDPE protective layer.
