The first domestic automatic steel pipe cleaning equipment with high cleanliness has been officially put into operation.

The stainless steel heat exchanger tube needs to be brightly annealed after rolling, and the oil stain on the surface of the steel tube must be cleaned thoroughly before annealing. The high temperature of the above steel pipe is produced by strong extrusion, and the liquid rolling oil forms solidified or carbonized dirt after high temperature, which is firmly attached to the micro-gap in the pipe wall, which can only be solved by the comprehensive means of manual beating white cloth (sponge ball) and chemistry. Chemical solvents generally choose VOC volatiles such as xylene, on-site VOC volatiles seriously exceed the standard, very affecting the health of workers; some solvents are also extremely flammable and explosive, a serious threat to production safety.

After many years of technical research and demonstration, the technical personnel of Ningbo Koni Tube Clean Technology Co., Ltd. have fully owned the high cleanliness automatic steel pipe cleaning production line with completely independent intellectual property rights, and completed the installation and commissioning on January 15, 2022. At present, it has been officially put into operation in the fine special workshop of Jiangsu Wujin stainless Co., Ltd. The cleaning agent is a low-temperature water-based degreasing agent. No VOC volatiles are used at the production site. After cleaning, it is tested that there are no water marks and no visible pollutants on the inner and outer surface of the steel pipe, and the cleanliness completely meets the annealing requirements. At present, the equipment is running normally, and the cleaning efficiency is 20m/ / 1-1.5min, which fully achieves the design goal.

Ningbo Koni Tube Clean Technology Co., Ltd., founded in 2014, is a high-tech service enterprise specializing in research and application of pipeline cleaning technology, science and technology consulting, production and sales of cleaning equipment and consumables.

Since the establishment of the company and before the establishment of the company, the core technical personnel have been committed to developing green and efficient cleaning technology for the steel pipe industry for more than ten years, and the company has fully mastered the small diameter steel pipe on-line degreasing technology and conventional steel pipe off-line degreasing technology; has applied for 20 national patents, authorized 15, and other technical secrets; It can provide personalized cleaning customization scheme for steel pipe enterprises, help enterprises to improve product quality and enhance the competitiveness of enterprises.
