Turnkey Project High-Pressure Air Type 508-1620mm Preinsulated Steel Pipe Making Machine and Polyurethane Spraying Foam Preinsulated Pipe Production Line

The polyurethane sprayed polyethylene thermal winding preinsulation pipe production line, independently developed by Huashida, consists of three parts: an external shot blasting and derusting collector production line, a polyurethane spraying production line, and a PE winding production line.

The line holds a number of national patents, and its third-party standardized evaluation report rates its technology at advanced level 5, reaching the domestic leading level. It has also been awarded the first set of technical equipment designation in Shandong Province.

The line adopts a continuous spraying production process. It offers high automation, fast production efficiency, raw material savings, increased foaming and closed-cell rate, lower water absorption rate, trinity molding, and more reliable performance. The resulting products are low-carbon and environmentally friendly, delivering higher economic and social benefits.

Producing technology flow of the polyurethane coating steel preinsulated pipe equipment:

1. Remove rust from the steel pipe surface
2. Preheat the steel pipe to prepare it for polyurethane spraying
3. Spray polyurethane evenly on the steel pipe outer surface
4. Wrap melted HDPE strap around the PU foam
5. Trim the pipe ends

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

The Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine by Huashida is ideal for manufacturing polyurethane insulated steel pipes. The PU steel tube insulation machine is designed for creating preinsulated steel pipes with high-quality insulation properties, and is suitable for applications where thermal insulation is crucial, such as hot chiller water, oil, and chemical material pipelines.

With its certification and origin from China, the machine meets quality standards and is backed by a reliable manufacturing process. The minimum order quantity of 1 unit allows for flexibility in acquiring the equipment. The price range of $1,000,000–$1,300,000 reflects its value and capabilities.

Delivered in a sturdy wooden box, the machine ensures safe transportation to its destination. With a delivery time of 2 months, customers can expect timely receipt of their order. The supply ability of 20 sets per year indicates the availability of the product.

Thanks to its high-pressure air type principle, the machine efficiently applies polyurethane foam insulation to steel pipes. The outer jacket material of High Density Polyethylene (HDPE) further enhances the durability and insulation properties of the pipes.

Overall, the Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine by Huashida is a reliable and efficient solution for producing polyurethane insulated steel pipes for various industrial applications.
