Connection MethodProduct Features Boasting uniformity in thickness, density, thermal conductivity, closed cell rate, and water absorption, our Pex pipe insulation ensures superior overall stability. Featuring minimal axis eccentricity and low thermal conductivity, our product excels at maintaining exceptional heat preservation. Our polyurethane online spraying process offers high reactivity and excellent bonding with both the steel pipe and the outer protective layer, ensuring the insulation pipe remains unaffected by temperature changes and free from delamination. With a smooth insulation layer surface and minimal thickness deviation, our product allows for a wide adjustment range. Utilizing polyethylene winding for the outer protective layer, our design results in a thin and uniform wall with minimal shrinkage, deformation, and stress, thereby solving the common issue of cracking in the protective layer. By reducing the thickness of the polyethylene outer protective layer, we cut costs while maintaining insulation performance. This leads to lower deformation and stress, significantly decreasing the protective layer's thickness.

These pipes boast uniform density and exceptional energy-saving capabilities, significantly enhancing heating transmission efficiency. As a cutting-edge, eco-friendly solution, they are setting new standards in sustainable construction. Qingdao West Coast Heating Pipeline Network Project Funded by a substantial investment of 217 million yuan from the Qingdao West Coast Public Utilities Group, this project revolutionizes the region's heating infrastructure. Originating from the Qingdao Special Steel heating first station, the pipeline extends 8.2 kilometers along the east bank of the Henghe River to the Binhai Avenue and the Hongkong Run Avenue Interchange, where it connects with the Huaneng long-distance heating pipeline. By integrating industrial park waste heat, industrial waste heat, and clean energy sources, and employing Donghong's DN1400-DN1200 spray-wound pre-directly buried insulation pipes, this initiative is pioneering a new era of energy saving and consumption reduction.CertificationsCompany Profile Welcome to Shandong Donghong Pipe Industry Co., Ltd.Shandong Donghong Pipe Industry Co., Ltd.
