PUR Foaming spray Preinsulation Pipe Continuous Production Line

Product Description

PU Foaming spary Preinsulation Pipe Continuous Production Line

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.

Top-tier HDPE casing extrusion line for PUR injected pre-insulated pipes. Production speed is fast, pipe dimension accuracy is precise, and every finished casing meets international quality standards. The equipment is well-engineered, low-noise, and designed for long-term heavy-duty use. Ideal for heating networks, geothermal systems, and industrial thermal transmission pipelines. Truly professional production machinery.

5 stars for this high-performance HDPE jacket pipe extrusion line! It works perfectly with PU foam pre-insulated pipe systems, creating strong, weather-resistant outer casing for municipal and industrial heating projects. The extruder is powerful, forming is one-time finished, and raw material utilization rate is very high. Stable continuous operation, solid mechanical design, and great cost performance. Exactly what our pipeline manufacturing plant needed.
