Polyurethane Spray Coating Equipment Steel Pipeline Anti-Corrosion & Thermal Insulation
The thermal winding pre-insulated pipe production line independently developed by Huashida consists of three integrated sections:
- External shot blasting & rust removal line
- Polyurethane (PU) spraying line
- PE winding line
This line holds multiple national patents. According to a third-party standardized evaluation report, its technology has reached an advanced level of 5, ranking at the domestic leading level. It has also been recognized as a "First Set of Technical Equipment" in Shandong Province.
The line adopts a continuous spraying production process featuring:
- High automation
- Fast production efficiency
- Raw material savings
- Improved foaming and closed-cell rate
- Lower water absorption rate
- Trinity (three-in-one) molding for more reliable performance
The products are low-carbon, environmentally friendly, and offer higher economic and social benefits.
