price impact estimate - Head THK.
(OP)
I want to quickly find out the price impact of changing thickness of a vessel head without contacting the fabricator. Following are the details
Material SA516 Gr 70N
2:1 Elliptical Head with 2" SF.
Original thickness: 1.9375"
New thickness: 1.625"
Is there a way to do it on my own? Is there any website that has tools for doing these quick checks, calcs?

The problem is, you don't know what's involved in making these until you contact the fabricators. One thickness might be out of the range of one machine, or it might be the difference between hot work and cold work, they might get rounded up differently, might match stock thicknesses, etc. And you'll probably find a fair range of price differences from fabrictor to fabricator.

I have purchased hundreds of vessels in the past and I strongley suggest that you openly communicate with your fabricator, otherwise you can just about gaurantee that the final product will not be what you want nor expected.
Although it sounds a simple change, the knock on affect (eg. nozzle reinforcement in heads, thickness transitions, weight etc....) may far outweight the head purchase cost.
Good Luck!
