Product Description
Product Description:
Shandong Donghong Pipe Industry Co., Ltd. presents a top-tier solution for insulating central heating and domestic water pipelines with our high-quality polyurethane-foam tubing. Engineered to withstand extreme temperatures from -50°C to 135°C, this tubing provides unparalleled protection and minimal heat transfer. Its robust construction ensures long-lasting durability and effectively prevents pipe damage. Furthermore, the tubing is highly resistant to chemicals, making it an ideal choice for a wide range of applications.
Our state-of-the-art rigid polyurethane spray polyethylene wrapped prefabricated direct-buried insulation pipe leverages cutting-edge technology to ensure uniform foam density and consistent insulation layer thickness. This groundbreaking design optimizes material usage and reduces labor expenses, offering a highly economical solution for the transportation of hot water at temperatures up to 140°C.
Connection Method
Product Features
Our Thermal Steel Pipe Insulation Lagging System stands out for its remarkable uniformity in core attributes such as thickness, density, thermal conductivity, closed-cell rate, and water absorption. This uniformity guarantees exceptional overall stability.
With minimal axis eccentricity and impressively low thermal conductivity, our system ensures outstanding heat preservation, delivering superior thermal insulation performance.
The on-line polyurethane spraying process boasts high reactivity, forging a robust bonding with both the steel pipe and the outer protective layer. This results in an insulation pipe that remains unaffected by temperature fluctuations, ensuring no delamination occurs.
The insulation layer features a flawlessly flat surface with minimal thickness deviation, offering a wide adjustment range to meet diverse requirements effectively.
Employing a polyethylene winding method for the outer protective layer, our system guarantees thin, uniform walls with minimal shrinkage, deformation, and stress. This ensures excellent mechanical properties and resolves the issue of cracking in the outer protective layer.
By reducing the thickness of the polyethylene outer protective layer, we achieve significant cost savings. Under identical insulation conditions, this reduction minimizes deformation and stress, allowing for a substantial decrease in the outer protective layer's thickness.

Appliation Cases
The Classic Project Cases
Qingdao Haiyang 4.5 Million Square Meters Nuclear Energy Heating Project This groundbreaking initiative stands as China's premier official nuclear energy heating website. Leveraging Donghong's innovative spray-wound, pre-direct buried thermal insulation pipes, this project epitomizes excellence. With uniform density and a commitment to energy savings, these pipes significantly enhance heating transmission efficiency, marking them as a pioneering solution in eco-friendly construction.
Qingdao West Coast Heating Pipeline Network Project
Spearheaded by the Qingdao West Coast Public Utilities Group, this project boasts an impressive investment of 217 million yuan. The heating pipeline extends from the Qingdao Special Steel heating first station, tracing along the east bank of the Henghe River and the north side of Binhai Avenue, covering 8.2 kilometers. Connecting at the Binhai Avenue and Hongkong Run Avenue Interchange to the Huaneng long-distance heating pipeline, this project embraces industrial park waste heat, industrial waste heat, and clean energy heating solutions. Utilizing Donghong DN1400-DN1200 spray-wound pre-directly buried insulation pipes, it establishes a new benchmark in energy conservation and consumption reduction.
