Description :
This product is a polyurethane prefabricated buried insulation pipe, which is widely used as an efficient and energy-saving pipe material for urban centralized heating, central air conditioning pipelines, and industrial steam transportation. Its structure is divided into three layers from the inside to the outside: working steel pipe, polyurethane rigid foam plastic insulation layer and high-density polyethylene (HDPE) or glass fiber reinforced plastic external protection pipe.
Main selling points and features:
1. Excellent thermal insulation performance: High density polyurethane rigid foam is used as thermal insulation material, with extremely low thermal conductivity, which can effectively reduce heat loss and achieve remarkable energy-saving effect. Compared with the traditional trench laying method, the heat loss can be reduced by 25% -40%.
2. Excellent anti-corrosion and waterproof capabilities: The outer protective pipe is made of high-density polyethylene material, which has extremely high mechanical strength and toughness, acid and alkali corrosion resistance, good waterproof performance, and can effectively protect the internal insulation layer and working steel pipe from soil moisture and chemical erosion, extending the service life of the pipeline to 30-50 years.
3. Convenient construction and low maintenance costs: Adopting the "pipe in pipe" prefabrication process, only interface insulation treatment is required on site, greatly shortening the construction period. Directly buried laying does not require the construction of a large trench and can be directly buried underground, saving construction costs and requiring minimal maintenance in the later stages.
4. Good mechanical strength: The overall structure is compact, with high compressive strength, able to withstand soil pressure and ground loads, and suitable for various geological conditions.
Typical usage scenarios:
Widely used in urban centralized heating pipelines, cogeneration projects, oil and gas pipeline insulation, chemical pipeline insulation, and building central air conditioning cold and hot water transportation systems in northern regions. Especially suitable for working conditions that require long-distance transportation of high-temperature steam or hot water, it is an ideal choice to replace traditional overhead pipelines and trench pipelines.
Target audience:
Municipal engineering construction units, thermal companies, petrochemical enterprises, infrastructure departments of large industrial parks, HVAC engineering contractors, and pipeline material purchasers.
