There are many kinds of stainless steel, so there are many ways to judge the pros and cons of stainless steel pipes. If you are still using magnets to absorb stainless steel pipes to judge the pros and cons of stainless steel, then you will be OUT. Today, the supply of high frequency welded pipe unit manufacturers teach you to judge the pros and cons of stainless steel pipe.
There are many kinds of stainless steel, so there are many ways to judge the pros and cons of stainless steel pipes. If you are still using magnets to absorb stainless steel pipes to judge the pros and cons of stainless steel, then you will be OUT. Today, the supply of high frequency welded pipe unit manufacturers teach you to judge the pros and cons of stainless steel pipe.
At room temperature, there are two types of stainless steel pipes: austenitic and ferritic. Austenite type is non-magnetic or weak magnetic, martensite or ferrite type is magnetic. However, in the production process of stainless steel pipe, its magnetic properties will appear due to different processing states or chemical composition fluctuations. Therefore, it is not entirely reasonable to judge the quality of stainless steel pipes by magnetism.
How to judge the pros and cons of stainless steel pipe? Nanyang machinery to tell you:
1) Look at the price. Significantly lower than the normal market price of stainless steel requires you to carefully identify the authenticity of the judgment.
2, look at the material. Familiar with some basic features and characteristics of stainless steel pipes, and make choices through on-site judgment.
3, look at the surface treatment. Observe whether the surface of the stainless steel pipe is bright, whether there is a black line, whether it is smooth, whether there is strain, crush, etc.; and stainless steel industrial pipes, such as automobile exhaust pipes, oil pipelines, etc., because they are used for industrial purposes, the stainless steel pipe The weld requirements are relatively strict, and it is necessary to observe whether the stainless steel pipe has missed welding, whether the thickness is uniform, etc.
There are many ways to judge the pros and cons of stainless steel pipes. Because the corrosion resistance of various stainless steels is different, not all of them are absolutely stainless. Manufacturers of high-frequency welded pipe units believe that the best way is corrosion test.
