Do you mean what kind of material to use?
Original poster, be cautious when entering the pressure vessel industry; if you don’t understand the rules, it’s easy to commit crimes.
It is recommended to find a qualified manufacturer or design institute that can design it for you, prepare the drawings, and provide relevant documents; otherwise, it is easy to violate the law
It’s possible to use pipes as the cylinder body; they are simple to work with. If the cylinder body isn’t particularly long, it’s better not to use welded pipes; although they can be used even if the length is significant, they’re still preferable to welded pipes
Seamless pipes can be used, and material re-inspection is required. I’m not sure what you mean by \"thick-walled pipes\", as it can lead to misunderstandings. As for welded pipes, well, they are special equipment after all, so various controls are quite strict.
I’m a complete beginner and have just entered this industry
So I’m coming here to ask for help from the experts; I’m a newbie
It is better to use seamless pipes directly, as they have no longitudinal welds.
For a tube with a diameter of 168, it is recommended to adjust the inner diameter to below 150; it is not considered a pressure vessel； Otherwise, materials should be selected from 150.2. If it is a chemical container, stricter Six-in-One regulations must also be followed. In the special equipment industry, it is crucial to avoid assuming things without basis.
Thick-walled pipes are acceptable based on strength calculations, while welded pipes are definitely not allowed
