When users purchase stainless steel heat exchange tubes, do they find that some stainless steel heat exchange tubes are bright and some are dim? What is the cause of this? In addition to the difference in light and shade, does it affect the quality? Let’s look down with these questions!
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 chooses Walsin Lihwa and Yongxing Special Steel parent materials as the leading material for the production of high-quality stainless steel, providing the most reliable and safest stainless steel pipes and fittings for global users.
The main factors affecting the surface brightness of stainless steel heat exchange tubes are as follows.
A raw material problem
1. Raw material quality
The quality of stainless steel heat exchange tubes produced by good raw materials will be good. This is because the element content of good-quality stainless steel strips is stable, so the surface brightness of the manufactured stainless steel heat exchange tubes is high and the color is bright; the stainless steel heat exchange tubes produced by poor raw materials The quality of the heat exchange tube is relatively poor, because the element content of the steel strip produced by the poor quality raw material is unstable, so the surface color of the stainless steel heat exchange tube is dull.
2. Raw materials
The hardness of the raw material of the stainless steel heat exchange tube is too low, it is not easy to polish during the polishing process, and it is easy to produce orange peel phenomenon in the deep drawing process, which affects the gloss; while the hardness of the raw material is high, the polishing effect is good , The surface gloss of the stainless steel heat exchange tube is good.
It is worth mentioning that the thickness of the stainless steel heat exchange tube is between 0.52 and 1.1 mm, and the polishing effect is better. If it is too thin or too thick, it will make it difficult to control the polishing force. If the force is large, it will cause deformation, but if the force is small, the polishing force for thick tubes cannot be achieved.
3. Defects in raw materials
If there are defects such as scratches, pits, scratches, and sand holes on the surface of raw materials, it will directly affect the production process of stainless steel heat exchange tubes, resulting in low surface color of the produced stainless steel heat exchange tubes.
Two manufacturing process
The polishing treatment used in the production of stainless steel heat exchange tubes is the most direct factor affecting the stainless steel heat exchange tubes. If the stainless steel heat exchange tubes are polished by external factors (such as temperature, humidity, etc.) If there is a problem in the process, the stainless steel heat exchange tube produced will have low gloss and dark surface color.
The above are some factors that cause the surface of the stainless steel heat exchange tube to be inconsistent in brightness and darkness. Do you understand it?
