When stainless steel heat exchange tubes are used for a long time, there will be more or less dirt, which cannot be completely avoided, so do you know how to remove these dirt?
Zhejiang Max Stainless Steel Co., Ltd. is a modern stainless steel pipe manufacturing enterprise integrating scientific research, production and sales. The company adopts advanced, efficient and mature production management mode. The company selects Walsin Lihwa and Yongxing special steel base materials as the leading materials for the production of high-quality stainless steel, providing the most reliable and safest stainless steel pipes and fittings for global users. CNMAX has a number of cold drawing production lines, as well as a number of cold rolling units, CNC lathes and processing centers, mainly producing seamless tubes, bright and annealed tubes, heat exchange tubes, pipe fittings, flanges and other products.
The fluid area of the stainless steel heat exchange tube is small, and the internal structure is more complicated. If it is cleaned with cleaning liquid alone, the sediment produced is not easy to discharge, and if it is cleaned with hydrochloric acid, it may cause corrosion due to the material of the stainless steel heat exchange tube. affect the subsequent service life.
After many repeated tests by personnel, it was found that the cleaning effect with formic acid is the best. The formic acid cleaning solution is added with buffer and surfactant, which can reduce the corrosion of the cleaning solution on stainless steel heat exchange tubes; it has been proved by chemical experiments on scale samples , formic acid can effectively remove scale; after acid solution immersion test, formic acid can effectively remove scale attached to the surface of the plate, and has little damage to the heat exchange tube.
CNMAX has always taken “quality assurance, professional service, and customer satisfaction” as its business purpose, and its pioneering, pragmatic, and innovative entrepreneurial spirit will continue to contribute to the quality of stainless steel products for the society, complement each other, and work together to create a better world.
