PUR Spraying Foam PE Wrapping Preinsulated Pipe Machinery

Product description

The polyurethane sprayed polyethylene thermal winding insulation pipe production line independently developed by Huashida, consists of three parts: External shot blasting and derusting production line, polyurethane spraying production line, and PE winding production line. The line has a number of national patents, and the third-party standardized evaluation report has a technology advanced level of 5, reaching the domestic leading level. And won the first set of technical equipment in Shandong Province.
The line adopts continuous spraying production process. High automatic, fast production efficiency, saving raw materials, increased foaming and closed cell rate, lower water absorption rate, trinity molding, and more reliable performance. Products with low carbon environmental protection have higher economic and social benefits.

Technological flow of the polyurethane coating steel preinsulated pipe equipment:

Steel pipe Load-up online---->External shot blasting ----> dust collector---->internal blow out---->lifting transport pipe trolley---->transport to chuck----> chuck hoist cylinder----> alignment chuck center---->mechanical arm station adjust---->chuck hydraulic clamping---->chuck guard at both ends----> carrier pipe servo transport---->IF heating----> PU foam spraying----> pipe load down line----> transport pipe ----> PE film wrapping----> water cooling---->cutting down pipeline---->trim end of pipe---->printing mark&loading down finished pipe---->sealing end of pipe

Composition of the polyurethane coating steel preinsulated pipe equipment:

1. Shot blasting rust removel machine

2. Medium-frequency induction heating furnace

3. Polyurethane spraying unit

4. Single screw extruder and diehead mould

5. Finished pipe ends trimming machine

6. Conveyers, racks and robotics to move and handle the pipe

7. Electrical system and PLC

Advantages of Huashida stand

The steel pipe stand can be installed within an error range of ± 80mm of the user's ground foundation. The height of the stand is adjusted by anchor mounting bolts. When installing the stand, a slope of 5 ‰ is reserved, making it easy to roll large pipe diameters. Reduce labor intensity. After the installation of the platform frame, the foundation of the platform frame shall undergo secondary grouting treatment, with a neat and generous appearance
