hi,
Could you type in your question more clearly? Number of plates? are you trying to put a mitred end closure?

Dear member,
If you got the diameter of the blank, then it is the plate size physically available are the informations you nedd to decide on the number of plates required for the blank. You need to join them before into sufficient ly enough for accomodating the blank plate onto joined plates. Standard plates sizes available are 2, 2..5 mts or even 1.6 mts wodth. length of the plate may vary such as 6, 5.6, 10, 12 mts of standard mill lengths.
After joining them you nedd to do ultrasonic test or radiographic tests to make joint as good as parent plate itself. Then go for marking the blank plate dimension on to it. Cut to size and use it for dished end pressing.
Hope this clarifies your doubt.

gentlemen,

Try to fit whole dish in one single plate so that you can avoid lot of stresses and if you are making in two or more plates, then there will be more stress and it required RT (100%). So go for one single plate.

well we use the dish end having 2 radius one knuckle and crown radius . having
formula like

r=.17 D
R=.906 D
sf =50
Height of dish end=.25 D

D= dia of tank

how can calculate the blank dia for dat.
