Description

(1) Technical field [0001] The invention relates to a spinning and closing machine for manufacturing large-capacity high-pressure seamless gas cylinders. (two), background technology [0002] Large-volume high-pressure seamless gas cylinders are widely used abroad to store and transport various compressed gases, such as natural gas, compressed air, oxygen, nitrogen, hydrogen, helium, etc. Compared with the small-volume low-pressure gas cylinders widely used in China, large-volume high-pressure seamless gas cylinders have the advantages of saving raw materials, low investment and transportation costs, less leakage, and convenient maintenance. With the country's "West-East Gas Pipeline" and the emphasis on environmental protection, the demand for large-volume high-pressure seamless gas cylinders is increasing year by year. The market capacity is expected to be huge in the next 10 years. Because there is a blank in the production of large-volume high-pressure seamless gas cyl...
