Technical Inquiries for API Standard 650,Welded Tanks

Does API 650 cover the design of a tank for a design vacuum condition of 50 mm of water? No.Per API 650 Section 3.2.4,the tank is limited to one in.of water vacuum (roughly 25 mm). If the tank must be designed for 50 mm water vacuum,then this is a special design which is not covered by API 650Tanks designed under API-650 can be designed for up to 2.5 PSI. On a tank of any size,designing for 2.5 PSI will have a major effect on the strucThanks Jstephen That is what I also thought.however,in the mean time.I referred API 620 as well for Tank design pressure. It dictates in tThe difference comes from the intent of the Code committee. API-620 has always been the primary Code for pressurized tanks. It shares alot of simThanks JoeTank,,,If API-620 has always been the primary Code for pressurized tanks.Why the title of API620 appears as:- Design and ConstructioWhat don't you understand? 15 psi is a low pressure. Joe TankokkkI am sorry.Infact I compared 15 psi with 2.5 psi and considered it relatively higher pressure while compared to API 650 2.5 psiand forGreater than 15 psi is a pressure vessel.Anything less can be designed to any code you wish,unless in your locale there is a law against it.API-ak1965,My sincere apologies if I sounded rude in my response. I did not intend to be so rude.
