Flange coated anti-corrosion steel pipe

Description :

　　The use of coated composite steel pipe products in many underground coal mine equipment includes the use of coated steel pipes for water supply and drainage, fire sprinkler, underground spraying, positive and negative pressure ventilation, and gas drainage pipelines. The environment of coal mines is different from ordinary environments. Using ordinary steel pipes underground can easily cause problems when subjected to impact forces. The use of new plastic coated pipe products can overcome the shortcomings of ordinary steel pipes, and plastic coated mining pipe products are lightweight, easy to carry, install, and maintain. In the renovation of municipal systems in many cities, coated steel pipes are used, specifically in anti-corrosion pipelines such as building water supply, natural gas, seawater transportation, and sewage. Coated steel pipes have the characteristics of plastic and steel pipes, are not easily deformed, corrosion-resistant, and rust resistant, and are more suitable for use in people's domestic water drainage. Coated steel pipes are also used in the transportation of many chemical products. Coated steel pipes play an important role in the transportation of corrosive media in industries such as petrochemicals, non-ferrous metal smelting, coking, and light industry.

　　Firstly, in terms of connection, coated steel pipes have the characteristics of easy connection and simple operation, saving a lot of manpower and material resources. Secondly, it has high corrosion resistance. Plastic coated steel pipes are coated with special materials both inside and outside, which can provide corrosion resistance. At the same time, the coating has good electrical insulation and other characteristics, and will not produce electrical corrosion. Thirdly, the longevity of use. Due to its high water absorption rate, high mechanical strength, and low friction coefficient, coated steel pipes can achieve long-term use for users without damage. Moreover, coated steel pipes have the advantage of effectively preventing damage to plant roots and soil environmental stress. The plastic coated steel pipe industry in China has developed rapidly, mostly used for lining polyethylene pipes in cold water, which is more similar in performance to metal pipes.

　　Current status of domestic applications. The use of steel plastic composite pipes has become relatively mature in developed countries, with North America and Japan being the main consumer areas for steel plastic composite pipes. For example, 70% -90% of water pipelines in countries such as the United States and Japan use steel plastic composite pipes. The annual consumption of steel plastic composite pipes in North America accounts for nearly 1/4 of the world's steel plastic composite pipe product consumption market. In China, steel plastic composite pipes are widely used in cities such as Shanghai, Beijing, Shenzhen, Hangzhou, Chongqing, Fuzhou, and Suzhou. In Shanghai alone, over 90% of high-rise buildings use steel plastic composite pipes. In addition, Qiu Xiangyu et al. used the surface water supply project in the Yanqing Plain area of Beijing as a design example to comprehensively compare and analyze the characteristics, hydraulic performance, engineering cost, and other aspects of various commonly used pipe materials in long-distance water transmission projects exceeding 10km. They finally concluded that steel plastic composite pipes inherit the advantages of steel pipes, but also have the advantages of low roughness, excellent anti-corrosion performance, and good hydraulic performance. They can be recommended as the preferred pipe material for long-distance water transmission projects. In terms of its production capacity, due to the lack of authoritative institutions in China specifically analyzing and investigating its production capacity, market demand, and consumption situation,

　　According to data provided by the Steel Plastic Pipe Federation of the Water Supply and Drainage Equipment Branch of the China Building Metal Structure Association and the China Market Monitoring Center, the domestic production of steel plastic composite pipes exceeded 1 million tons in both 2009 and 2010. The steel plastic pipe industry has more varieties and series of products, and the application of steel plastic pipes has also expanded to multiple fields. Corresponding products have been developed in various fields such as urban construction water supply and drainage, municipal water supply, fire water supply, and coal mine water supply and drainage. From the perspective of water supply and water supply, there are currently the following types of steel plastic pipes: China Pipeline looks at Hebei, Hebei Pipeline looks at Yanshan, and Yanshan Pipeline looks at Guanghui.
