Connection MethodProduct Features Our Ferro-Therm pre-insulated pipes boast uniformity in core indicators such as thickness, density, thermal conductivity, closed cell rate, and water absorption, ensuring exceptional overall stability. Engineered with minimal axis eccentricity and low thermal conductivity, these pipes deliver superior heat preservation, making them highly efficient. Featuring online polyurethane spraying with high reactivity, our pipes exhibit excellent bonding with both the steel core and outer protective layer. The insulation remains stable against temperature changes, without any delamination. The insulation layer is meticulously crafted to have a flat surface, minimal thickness deviation, and wide adjustment range, ensuring precise application. Our innovative polyethylene winding method for the outer protective layer results in thin, uniform walls with low shrinkage, minimal deformation, and stress. This significantly improves overall mechanical properties and resolves cracking issues. Cost-effective design reduces the thickness of the polyethylene outer protective layer while maintaining insulation performance, thus lowering deformation and stress and significantly cutting costs.
