Have you ever encountered low brightness on the surface of stainless steel heat exchange tubes during the use of stainless steel heat exchange tubes? So how is this caused? Mingxin will answer below!
Zhejiang Mingxin Stainless Steel Co., Ltd. is a modern stainless steel pipeline system manufacturing enterprise integrating scientific research, production and sales. The company adopts advanced, efficient and mature production management mode. Leading materials for the production of high-quality stainless steel, to provide reliable and safe stainless steel pipes and pipe fittings for global users.
1. Caused by raw materials
① The raw material quality of stainless steel heat exchange tubes is related to the production of stainless steel heat exchange tubes. Good raw materials can produce good products. This is because the element content of good material steel strips is stable, and the surface brightness of the produced stainless steel heat exchange tubes is high. ; The stainless steel heat exchange pipe strip produced from inferior raw materials has unstable element content, so the surface brightness is low.
②The problem of material hardness of the raw materials of stainless steel heat exchange tubes. If the hardness of the material used for the raw material of the steel pipe is too low, it will make it difficult to polish the heat exchange tube. At the same time, it is easy to have an orange peel phenomenon on the surface during deep drawing, resulting in low brightness on the surface of the stainless steel heat exchange tube. However, if the material hardness is high, the polishing effect will be better. The surface gloss of stainless steel heat exchange tubes is also very good.
The polishing effect of stainless steel heat exchange tubes with a thickness between 0.52-1.1mm will be better, because if the thickness is too thin or too thick, the polishing will be difficult to control.
③ Defects on the surface of stainless steel heat exchange tubes (pittings, scratches, scratches and blisters, etc.) will affect the production process of stainless steel heat exchange tubes, resulting in low surface brightness of the produced stainless steel heat exchange tubes.
2. Influence of polishing process
The polishing process of stainless steel heat exchange tubes will have a direct impact on the surface brightness of stainless steel heat exchange tubes.
When polishing stainless steel heat exchange tubes, due to the influence of external factors such as temperature and humidity, the polishing process of stainless steel heat exchange tubes is prone to problems, so the outer surface of the produced stainless steel heat exchange tubes has low brightness and dark color.
