City heating polyurethane insulation steel pipe manufacturer

Tianze Pipe Industry Group is a large polyurethane foam insulation steel pipe manufacturer in North China. Our company's direct sales of polyurethane foam insulation steel pipes have advantages in price and guaranteed quality. Black jacket polyurethane insulation steel pipes, polyurethane foam insulation steel pipes, polyurethane direct buried insulation steel pipes, Polyurethane insulated seamless steel pipe, polyurethane insulated steel pipe for heating. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, it isolates the infiltration of air and water and can play a good anti-corrosion role. At the same time, its foaming holes are closed and its water absorption is very small. Both high-density polyethylene shell and fiberglass shell have good anti-corrosion insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by outside air and water. As long as the internal water quality of the pipeline is well treated, according to foreign data, the service life can reach more than 10 years, which is ~ times longer than the service life of traditional trench laying and overhead laying. Directly buried heating pipes do not require the construction of huge trenches, and only need to bury the insulated pipes underground, thus greatly reducing the project area, reducing the amount of earthwork excavation, and reducing the amount of earthwork masonry and concrete. At the same time, the insulation pipe processing and on-site trenching are carried out in parallel, and only on-site joints are needed, which can shorten the construction period by more than approximately. The use of thermal insulation materials in insulated steel pipes can maintain warmth and sound insulation, improve living comfort, and is conducive to energy conservation and emission reduction. Don’t underestimate the contribution of thermal insulation materials to energy conservation and emission reduction. In the development goals of building energy conservation, the contribution rate of building energy conservation must reach 100 million tons of standard coal. Of course, all this needs to be based on the premise of safety and reliability. Insulation materials can be laid on interior walls, but in practice the insulation effect is not ideal, so insulation materials are usually laid on exterior walls. The main civilian exterior wall insulation materials available on the market include polystyrene extruded boards and polyurethane foam. The first two materials were used earlier than polyurethane foam. There are still some buildings using these materials. Compared with polystyrene board and extruded board, polyurethane foam has the advantages of good thermal insulation performance, good heat resistance, long service life, light weight, easy transportation and convenient construction. It also has good water resistance, but the price is slightly higher. Polyurethane foam has gradually replaced them as the pipe insulation material of choice.
At present, my country has formed a complete production system of polyurethane raw materials and downstream products. Not only does the output of polyurethane foam, polyurethane elastomer, polyurethane synthetic leather slurry rank first in the world, but it is also a major exporter of a variety of polyurethane products. my country has built a number of polyurethane industry clusters in the Yangtze River Delta, the Yellow River Delta, the Bohai Sea, the Pearl River Delta, the Northeast, Southwest, etc., forming a pattern of raw material production and downstream product processing in which leading enterprises drive many small and medium-sized enterprises to coexist. In the past ten years, my country's polyurethane industry has continued to promote industrial upgrading, expand the production scale of specialized raw material products, vigorously develop scientific and technological innovation, strengthen the research and development of safe and environmentally friendly production technologies, environmentally friendly product substitutions, and energy conservation and emission reduction, resource recycling, etc., scientific research and development capabilities Products reaching a new level have developed towards refined functionality, high performance, and further expanded application areas.
