The greatest advantage of Alloy Steel Pipe is that it can be recycled 100%, which is in line with the national strategy of environmental protection, energy saving and resource saving. The national policy encourages the expansion of the application field of high pressure Alloy pipe.At present, the proportion of China's alloy pipe consumption in the total steel is only half of the developed countries, the expansion of the use of alloy pipe field to provide a broader space for the development of the industry.According to the research of the expert group of alloy pipe branch of China Association of Special Steel, the demand for high pressure alloy pipe length in China will increase by 10-12% annually in the future.Alloy pipe is the steel pipe in accordance with the production of material (that is, material) to define, as the name implies is the alloy of the pipe;And seamless pipe is the steel pipe in accordance with the production process (seamless) to define, is different from seamless pipe is seamed pipe, including straight seam welded pipe and spiral pipe.
