Reasons for cracks in stainless steel seamless elbows during use:
①[Raw material factors]
Poor quality tube blanks will have internal and external warping, scarring, cracks, etc.;
②[Temperature factor]
An important process in the production of seamless elbows is heating. Poor heating (uneven, insufficient temperature, etc.) will cause warping of the skin;
③[Equipment factors]
From the moment it comes out of the furnace, each equipment component will affect the final quality of the pipe. For example, the scraping of equipment parts will cause the skin to warp outwards and dents; the unsmooth entry into the punching machine will cause the head of the tube blank to be exposed to water and make it difficult to bite in, or the skin of the head will warp inside;
④[Processing issues]
The process problems are also quite complicated, including adjustment problems, equipment failure problems, and pipe quality problems caused by wear and tear of process components (heads, guide plates, rollers, etc.). The problems caused are all-encompassing.
