Type of dished end for small tanks

Srinu,

You are new to this forum so I say "Welcome". I hope you are able to find the right answers to your questions.

Something that will help you get the "right" answer is to know how to ask the "right" question. More important, how to ask the question the "right" way.

The "right" way to ask technical questions is to establish the context for the question (background and reason). If toy do not do this then we cannot be expected to give you a "right" answer.

We do not know why you are asking this "dished head" question so we can only guess.

Check out the following web-sites:

Then come back with some better explanations and questions.

check out ASME section VIII Div - 1 for the type n other details.
