How to distinguish the quality of stainless steel pipes
In the application of stainless steel pipes, stainless steel pipes are one of the most common raw materials. However, many people do not know how to select stainless steel pipes. So, how can we distinguish the quality of stainless steel pipes? Let’s take a look together with the stainless steel pipe manufacturer.
Methods for distinguishing the quality of stainless steel pipes
What is a shrinkage cavity? A shrinkage cavity is when the stainless steel molten material is in a liquid state and shrinks inside the mold. Sometimes, due to environmental factors such as air and temperature, some shrink cavities will form. From a professional perspective, this is called a shrinkage cavity.
The cross crack is relatively easy to understand. It is a crack that occurs on the surface of the stainless steel pipe. Generally, this kind of crack occurs during the steel ingot stage, but most of them are shallow in depth.
Knowing the cross crack, then the meaning of longitudinal crack is obvious. Longitudinal crack is a longitudinal crack on the surface of the steel ingot. It usually occurs in the upper part and corners. The longitudinal crack that appears on the top is usually deeper.
As mentioned above, longitudinal cracks may occur in the upper part or corners of the stainless steel pipe. Sometimes, in the lower part area, there may also be metal splatter or tumor-like metal deposits, which looks like a scar. So it is called a scar. However, this problem rarely occurs.
