Cracks on the surface of stainless steel seamless elbows are caused by many factors, including raw materials, temperature, equipment and process issues.
Let’s talk about the problem of raw materials first. If the raw materials selected for stainless steel seamless elbow are of poor quality, there will be internal and external warping, cracks, scarring and other phenomena.
In terms of temperature, the heating process of stainless steel seamless elbow is very important. Uneven heating or insufficient temperature will lead to warping of the skin.
Then there are the equipment issues. Each equipment component can affect the final quality of the stainless steel seamless elbow. For example, scratches on the equipment components will cause warping and pits, and failure to enter the punching machine will cause the head of the tube blank to be damaged by water. It is difficult to bite in, or the skin on the head is warped.
Finally, there are process issues. The process issues of stainless steel seamless elbows are very complex. Specifically, they include adjustment issues, equipment failure issues, and quality issues caused by wear and tear of process components.
