Fully Automated Production Line for Pre-Insulated Steel Pipes: Computer-Controlled PU Foaming and HDPE Cladding

Product Description

Fully Automated Production Line for Pre-Insulated Steel Pipes: Computer-Controlled PU Foaming and HDPE Cladding

1. Production line introduction
Polyurethane (PU)spraying polyethylene(PE) 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.

3. Technological flow:

The spraying and winding production process ensures the uniformity of the density of the insulation layer, improves product quality, and reduces production costs.

4. PUF spray PE winding preinsulated pipe production line consists of the following parts:

1) Steel pipe outwall shot blasting line

2) Polyurethane spray molding line
3) Polyethylene sheet extruding winding line
4) Water cooling line
5) End-cutting equipment

Main line Composition of the polyurethane coating steel preinsulated pipe equipment:

No.	name
1	External wall Shot blasting rust removel machine
2	Medium-frequency induction heating furnace
3	Polyurethane spray foaming unit
4	pipe rotator trolley
5	Single screw extruder and diehead mould
6	Finished pipe ends trimming machine
7	pipe Conveyers and racks
8	Electrical system and PLC

5. Advantages of Polyurethane spray insulation pipe:
1). The density of polyurethane is uniform and controllable.
2). Polyurethane rigid foam has no empty spaces.
3). The surface of polyurethane foam is rough, the shear strength (friction) to the polyethylene outer casing is greater than 200Kpa.
4). The thickness of the polyurethane insulation layer and the thickness of the polyethylene outer casing can be adjusted according to the design.
5). The production has a high degree of automation.
