Best Gasket/seal for pressure vessel

Best Gasket/seal for pressure vessel

Best Gasket/seal for pressure vessel

(OP)
I'm sealing a 5ft X 2ft opening on a pressure vessel filled with water (144psi).  Opening will be covered with a flat aluminum plate.  The plate will be bolted to the surface of the pressure vessel.  What is the best type or style gasket for the job?  How do you calculate the thickness needed and the material of the gasket?  How do you figure out member stiffnes K(m) for a gasket?  Is there a reference that covers gasket formulas, material properties, and constants?  

Thank you,
Billydelo

Try these:
D.V.Cook & B.G.Guerreri, "Deflection in Gasketed Joints," Machine Design, March 14, 1968, pp.149-150.

http://www.garlock.net/ look under "product catalogs" for "Engineered Gasketing Products"

Marks Handbook Ch. 8 Fig 37 "Compressibility of Gaskets"

RE: Best Gasket/seal for pressure vessel

billydelo, There are three items that makeup a sealed connection; flange, gasket, bolts. For the gasket it must fulfill the following:

1. Must be conformable to the flange faces
2. Must exhibit resistance to hi temp., high surface press., and chemical attack.
3. Must remain tight at all service conditions.

For your application I would recommend either red rubber (std. low temp. water service type gasket) or a composition type gasket (better at high temp.)

For information on gaskets and gasketed joints, pickup the book, "Gaskets & Gasketed Joints" by John H. Bickford, publisher Marcel Dekker of New York, NY.

Hope this helps.

RE: Best Gasket/seal for pressure vessel

Billydelo, read ASME V111 for the design of the flat bolted plate , it will be rather thick for that size of hole especially made from aluminium. the gasket is the least of your worries

RE: Best Gasket/seal for pressure vessel

Billydelo, you can find some calculations on ASME BOILER & PRESSURE VESSEL CODE, Section 8 Division 2. Go to article 3-3 "Flanges with Ring Type Gaskets" on page 282.
