Industrial Steel Pipe Featuring Sprayed PU Foam and Wound PE Outer Jacket

First, the polyurethane is sprayed directly onto the steel pipe surface, forming a tight bond with the pipe. Second, the polyethylene outer pipe is wound and fixed outside the insulation layer, forming a solid protective layer. Third, this structure enhances pressure resistance and service life. Fourth, the production line is compact with fewer links, which reduces production cost. Fifth, it adapts to complex environments and pipe shapes and greatly improves construction efficiency

Yes. We determine a reasonable insulation layer thickness according to the medium temperature, ambient conditions and heat loss requirements of each project. This avoids unnecessary excess quality and reduces material cost. You only pay for the thickness actually needed to meet thermal, anti-corrosion, protection, transportation and installation requirements.

The long-term operating temperature should not be higher than 120 degree centigrade and the occasional peak value should not be higher than 140 degree centigrade. This makes it suitable for district heating, high-temperature hot water and many industrial thermal insulation projects. If your medium temperature is higher, please tell us and we can recommend a suitable insulation solution.

It can adapt to various complex environments and pipe shapes, including straight pipes, bends and special sections. The spraying and winding process allows the insulation layer and outer protective layer to closely follow the pipe surface, so it works well in projects where traditional processes are difficult to apply. This greatly improves construction efficiency and reduces on-site processing.
