Which standard specifies the thinning rate for head forming?
GBT 25198-2010 on the pressure vessel head
Found it, thank you. By the way, I would like to ask: what is the reduction rate in thickness for EHA end caps with a diameter of 2600 and a thickness of 72?
According to this standard, the diameter is 2600 and the thickness is 72 mm; what should be considered if these values exceed this range?
There are some end cap standards…%&*
The standards are merely a reference; the products manufactured by different manufacturers can vary. Whichever type of end cap you choose, the manufacturer can provide it
The thickness reduction amount: the standard for end caps is usually the maximum value; generally, end cap manufacturers will make them slightly thinner than this standard. If it exceeds this range, it is necessary to negotiate with the end cap manufacturer.
You can discuss this with the head cover manufacturer; they will be able to give you an answer. Decide first before cutting the blank
A new draft for comment has been released recently under GB/T 25198. This new draft specifies different thinning rates corresponding to various processing methods; here is a screenshot for you:
