Polyurethane insulation steel pipe manufacturer

Tianze Pipe Industry Group is a large polyurethane foam insulated steel pipe manufacturer in North China. Our company directly sells polyurethane foam insulated steel pipes with favorable prices and guaranteed quality. Black jacket polyurethane insulated steel pipes polyurethane foam insulated steel pipes polyurethane direct buried insulated steel pipes polyurethane insulated seamless Polyurethane insulated steel pipes for steel pipe heating. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, it can prevent the penetration of air and water and play a good anti-corrosion role. At the same time, its foaming holes are closed and have very little water absorption. 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 be more than 10 years, which is ~3 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 and the amount of earth excavation by about % and reducing the amount of civil masonry and concrete by about %. At the same time, the insulating pipe processing and on-site trenching are carried out in parallel, and only on-site joints are required, which can shorten the construction period by more than %. The use of thermal insulation materials in insulated steel pipes can maintain warmth and sound insulation, improve living comfort, and is beneficial 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 %, which means saving 0.1 billion 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, convenient transportation and convenient construction. It also has good water resistance and 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. Our country has built a number of polyurethane industry clusters in the Yangtze River Delta, Yellow River Delta, Bohai Sea, Pearl River Delta, Northeast, Southwest and other areas, 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 substitution, and energy-saving and emission reduction, resource recycling and other scientific research and development capabilities have reached a new level of products. It has developed towards refined functionality, high performance and further expanded its application fields.
On May 1, it was reported that Malaysia’s Second Minister of International Trade and Industry, Huang Jiaquan, said that China’s ongoing overcapacity reduction policy is beneficial to the development of the local steel industry in Malaysia. Malaysia can seize the opportunity to carry out production capacity cooperation with Chinese steel companies. He said that the Chinese government will adopt an overcapacity reduction policy this year and plans to reduce the annual output of crude steel by 100 million to 100 million tons within three years from this year, so that China's crude steel production and sales will become more balanced and stabilize international steel prices. Huang believes that China needs to strike a balance between obtaining cheap steel and ensuring the survival of local steel plants as China's reduction in steel production has led to higher steel prices in Malaysia, which has affected the development of the real estate industry. Failure to protect local steel mills may lead to their collapse, while the construction sector will experience raw material shortages if foreign supplies of steel are not available.
