Continuous Line For Steel Pipe PU Spraying Foam Pre Insulated Pipe Making Fast Production Efficiency

Continuous Line for Steel Pipe PU Spraying Foam Pre Insulated Pipe Makingfast production efficiency

 
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.

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:
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



Other supplier racks
 
The integrated welded structure, without adjustment devices, cannot be installed when the ground is uneven. The height of the stand cannot be adjusted, resulting in uneven rolling of steel pipes on the stand, too fast rolling, or difficult rolling, which poses a safety hazard.
