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.
Stainless steel heat exchange tubes can be divided into straight tube heat exchange tubes, bellows heat exchange tubes and spiral heat exchange tubes. It is placed in the cylinder and is one of the elements of the heat exchanger, used for heat exchange between two media. So do you know the following two processing techniques for stainless steel heat exchange tubes? Next, Mingxin will introduce you!
One is heat treatment:
The heat treatment of stainless steel heat exchange tubes actually refers to solution heat treatment. All stainless steel heat exchange tubes need to be heat treated. The hardness of the U-shaped heat exchange tube bend without heat treatment and sub-solution treatment will increase with the decrease of the bending radius, so this is the reason why the pipe fittings need to be heat treated. We also need to pay attention to controlling the solid solution temperature when heat-treating stainless steel heat exchange tubes. Low temperature will affect the treatment effect, making it difficult to achieve the desired effect on the structure and hardness of the pipe fittings. High temperature will cause concave or cracks on the inner side of the pipe fittings. wait.
The other is sanding:
The grinding treatment of stainless steel heat exchange tubes is often used in dry grinding processing, ink drawing and 8K mirror processing. Ink drawing is used more often. Stainless steel heat exchange tubes can show a good decorative effect after ink treatment. The frosted surface is more delicate and uniform, and the anti-rust effect is also better!
The above is an introduction to these two processes.
