What are the causes of deformation of 304 stainless steel pipes?

The first is the material defect of 304 stainless steel welded pipe during production. Many materials will deform after heating, and some materials will also deform under high pressure. During the use of this product, it will also be deformed due to various reasons.
Therefore, when customers purchase this product, they should first understand its product materials. Not only does the material need to have sufficient strength, but it also needs to be seen whether it can remain stable under the operating temperature, such as 900C. At this time, 304 cannot be used, because when it is used in an environment of 500°C, the tensile strength, hardness, and yield strength of the steel pipe are declining. At this time, materials that can withstand higher temperatures need to be considered.
There are also some 304 stainless steel pipes that are deformed because the manufacturer's production process is not perfect. In the production of this product, both the forming process and the surface treatment process need to meet certain requirements. As a matter of fact, if the manufacturer's craftsmanship is not in place, the quality of the product will naturally decrease, resulting in deformation during work. Of course, different products will also have great differences in the deformation time. For example, some products will deform just after installation, and some will deform after being used for a period of time.
Of course, some 304 stainless steel pipes are deformed due to aging during use. Some aging is due to the shortcomings of the product itself; some aging is due to the medium. For example, a layer of scale will form on the inner wall of the pipe when used in a high-pressure environment. , and this accumulation of scale will eventually deform it and make it unusable. This also requires the product's environmental resistance and anti-aging to be improved, but this requires the manufacturer to improve the materials and processes. improve at the same time.
The above are the reasons for the deformation of 304 stainless steel pipes. From the above introduction, you can know that the reasons for the deformation of stainless steel pipes include material defects, substandard production processes, and aging and deformation during use. Therefore, manufacturers need to improve their raw materials and production processes to avoid deformation of 304 stainless steel pipes.
