The first set of high-cleanliness automatic steel pipe cleaning equipment in China was officially put into operation
The stainless steel heat exchange tube needs to be bright annealed after rolling, and the oil stain on the surface of the steel tube must be thoroughly cleaned before annealing. The above-mentioned steel pipe is subjected to strong extrusion to generate high temperature, and the liquid rolling oil forms solidified or carbonized dirt after high temperature, which is firmly attached to the microscopic gap of the pipe wall. The chemical solvents generally use VOC volatiles such as: xylene, etc. The VOC volatiles at the production site seriously exceed the standard, which greatly affects the health of workers; some solvents are also extremely flammable and explosive, which seriously threatens safe production.
