Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a steel pipe clamp. Background technique [0002] The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save metal by 20-40%, and realize factory-like mec...

AI Technical Summary

Problems solved by technology

[0003] Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and save metal by 20-40%. , and can realize factory-like mechanized construction. The use of steel pipes to manufacture road bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. Therefore, steel pipes are more and more widely used in the construction industry. In the process of application, steel pipes will meet the need for clamping and positioning. For small steel pipes, the positioning and clamping can be realized by quick clamps, etc., but for some steel pipes with larger diameters, positioning and clamping Accuracy cannot be guaranteed
