Description :
This product is a prefabricated buried polyurethane insulated steel pipe, widely used in urban centralized heating, heating engineering, and industrial pipeline transportation systems. The product structure is composed of inner working steel pipe, middle polyurethane rigid foam insulation layer and outer high density polyethylene (HDPE) protective sleeve, forming a "pipe in pipe" composite structure.
Main selling points and features:
1. Efficient thermal insulation and energy saving: high-quality polyurethane rigid foam is used as thermal insulation material, with low thermal conductivity and high closed cell rate, which can effectively reduce heat loss and achieve remarkable energy saving effect, meeting the requirements of modern green buildings and energy conservation.
2. Excellent anti-corrosion and waterproof performance: the outer layer of high-density polyethylene sheath has extremely strong chemical corrosion resistance and aging resistance, as well as excellent waterproof and moisture-proof functions, which can protect the internal steel pipe from soil and groundwater erosion for a long time, and extend the service life of the pipe up to 30-50 years.
3. High mechanical strength and good integrity: the polyurethane foam is firmly bonded with the working steel pipe and the external protective pipe to form a trinity overall structure, which can withstand large external loads and soil pressures, and is suitable for direct burial laying, without the need to build trenches, greatly reducing the cost of civil construction.
4. Convenient construction and low maintenance costs: Prefabricated production, on-site installation only requires welding interfaces and patching treatment, with fast construction speed and short construction period. Due to the low failure rate, the later operation and maintenance costs are extremely low.
Typical usage scenarios:
Suitable for centralized heating pipelines in northern regions, steam or hot water transportation pipelines of thermal companies, insulation of oil and gas pipelines, and medium transportation pipelines in the chemical industry. Especially suitable for direct burial in areas with high groundwater levels and strong soil corrosiveness.
Target audience:
Municipal engineering contractors, procurement departments of heating companies, construction and installation engineering companies, pipeline construction managers in industrial parks, and equipment and material purchasers.
