	Hello all, If this question is redundant on my part, I'm not sure that I sent the first question right so I thought I would try again and re-worded,(since I can't remember how I asked). Can a 5800 psi vessel be built under Sec 8 Div1 at the expense of size and weight? e.g. thicker walls, heads, nozzels and flanges.

	What is in the vessel, how much of it and at what temperature? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	The vessel is a sand seperator and will have a mixture of sand, oil, water and gas. Current spec say5800 MAWP @100 Deg F.Shell is 20" OD with Hemispherical heads. Thanks

	TR, A vessel can be built to the conditions you describe under the rules of the ASME Boiler & Pressure Vessel Code, Section VIII. The special rules for high pressure vessels (>3000 psig) will apply. I do not understand what you mean by: "at the expense of size and weight".... Your vessel wall thickness for this diameter and extreme pressure will be approximately 4 inches. __________________ We have met the enemy....and he is us. POGO

	"Expense of Size and weight" meaning will Sec 8 Div 1 allow a vessel to be built with bigger and thicker components or will the pressure dictate what division must be used such as div.2 or 3.
