How are pipe caps made? Is the material a sheet?

Is the pipe cap made of sheet metal?
You can take a look at GB/T13401-2017
Since material standards often use GB711 or GB713, it should be made of sheet metal; however, I’m not sure. So I need to ask my friend. There are many materials available under code 13401, but it’s not clear whether pipe caps should be made from pipe material or sheet metal – it depends on how they are manufactured
I’ve watched the video; those with thick walls are made by hot stamping of sheet metal, while those under high pressure are likely forgings. You can check the manufacturing standards
The vast majority of pipe caps are formed by pressing sheet metal (by stamping or spinning), while those that are small or very thick may be made by forging or machining from rods. .
Are pipe caps rarely used? Basically, blind flanges have been used in their place
