Half, 12Cr1MoVG alloy steel pipe in the field using 12cr1movG present, China's total consumption accounts 12Cr1MoVG alloy pipe steel in developed countries accounts for only expanded to provide a broader space for development of the industry. Based on the Chinese Special Steel Association 12Cr1MoVG ship alloy pipe fittings Hebei branch of the future growth of China's annual demand for high-pressure alloy pipe 12Cr1MoVG longs up to 10-12%. 20g 20G seamless steel pipe seamless steel pipe is a hollow cross section, no seams around the long bar of steel. Ships with a hollow section steel pipe manufacturers, a large number of used pipes conveying fluids, such as the transportation of oil, natural gas, gas, water pipes and some solid materials, and so on. Steel tube and solid steel bar, etc. Compared ship fittings, the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive transmission , bicycle frames and construction using steel scaffolding. Ring with steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material, gun barrels to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. As in the perimeter of equal conditions, the largest area of ??a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of the pipe is pipe. However, the tube also has some limitations, such as under the conditions by plane bending, tube as good as square, rectangular tube large flexural strength, the skeleton of some farm machinery, steel and wood furniture on the popular square, rectangular tube. Depending on the application should also have other cross-sectional shape shaped pipe.
