Alloy pipe is a kind of seamless steel pipe, its performance is much higher than that of the general seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature, low temperature and corrosion resistance, the ordinary carbon seamless pipe does not contain alloy or alloy components, alloy pipe is widely used in petroleum, aerospace, chemical, power, boiler, military and other industries. The reason is that the mechanical properties of alloy tubes are well adjusted.
It can be recycled by 100%, which conforms to the national strategy of environmental protection, energy saving and resource saving. The national policy encourages the expansion of the application fields of high pressure alloy tubes. At present, the proportion of alloy pipe consumption in total steel products in our country is only half of that in developed countries. The expansion of the application field of alloy pipe provides a broader space for the development of the industry. According to the research of expert group of alloy pipe branch of China Steel Association, the demand for long high-pressure alloy pipe in China will increase by 10-12% annually in the future.
