A steel pipe finishing device. At present, a kind of equipment for grinding the inner wall of steel pipe at home and abroad is boring and grinding machine. It is necessary to replace different grinding heads when processing steel pipes with different apertures, which has high equipment cost, many spare parts for grinding heads and low productivity.

The other is the grinding equipment only for the inner and outer circles of steel pipe ends, both of which have their own limitations.

Second, the steel pipe introduction:

The development of steel pipe production technology began with the rise of bicycle manufacturing industry, the development of oil in the early19th century, the manufacture of ships, boilers and airplanes during the two world wars, the manufacture of thermal power boilers after the second world war, the development of chemical industry, and the drilling, production and transportation of oil and gas, all of which strongly promoted the development of steel pipe industry in variety, output and quality.

Steel pipe is not only used for conveying fluids and powdery solids, exchanging heat energy and manufacturing mechanical parts and containers, but also an economical steel. Using steel pipes to make grids, columns and mechanical supports of building structures can reduce weight, save 20-40% metal and realize mechanized construction of factories. Using steel pipes to make highway bridges can not only save steel and simplify construction, but also greatly reduce the area coated with protective layers and save investment and maintenance costs.
