Stainless steel heat exchange tube | production and processing

Stainless steel heat exchange tube is one of the main components of a heat exchanger. By its name, it should be known that it is actually used to exchange heat between two media. It directly affects the heat exchange work and results of the entire radiator. The production and processing of stainless steel heat exchange tubes require a series of steps. To ensure the quality of stainless steel heat exchange tubes, it is necessary to do a good job in all aspects of production and processing, Next, let me introduce to you what processing is required for stainless steel heat exchange tubes.

1. Heat treatment is actually a solution heat treatment of stainless steel pipes. The hardness of U-shaped heat exchange pipe bends without heat treatment or sub solid solution treatment increases with the decrease of bending radius. Therefore, in order to better use stainless steel heat exchange pipes, it is necessary to perform solid solution heat treatment on stainless steel pipes. It is worth noting that the low solution temperature affects the effectiveness of solution treatment, and the microstructure and hardness of stainless steel heat exchange tubes cannot achieve ideal results; If the temperature is slightly higher, defects such as concave or cracks may appear on the inner side of the stainless steel U-shaped pipe section.

2. Polishing treatment is commonly used in industries such as dry grinding, oil grinding wire drawing, and 8K mirror surface processing. Among them, oil grinding wire drawing is more commonly used because 304 series stainless steel exhibits good decorative effects after oil grinding, with a more delicate and uniform frosted surface and more prominent rust prevention effect.
The above two points are the main processing methods for stainless steel heat exchange pipes. In addition to the selection of raw materials, these two points are also quite important. Of course, if you need to purchase stainless steel heat exchange pipes, you can directly choose a manufacturer with quality assurance.
