Lately (late in my career), that is for past three years, i’m working on various ERPs. Offcourse i started the work on engineering domain. But thanks to my friends in other domain, who helped me in understanding other modules too. In my recent company i’ve developed my own ERP. it was made to take care […]
Whats is Earth quake factor? and how they affect the calculation? Their are numerous papers on this, and they are equally qualified to tell you what is earthquake factor all about… but what mater to me is.. how do they do it! As far as India is concern..The earthquake of 26 January 2001 in Gujarat […]
All designers are accustomed to evaluating moments due to eccentric and wind loads, but there are a few who may not be familiar with the method used for estimating moments due to earthquake. Therefore, the following brief outline is presented because this method is recommended as a design procedure for vessels where dynamic considerations are […]
It is customary for most vessel designers to establish the minimum vessel shell and trend thickness according to the pressure temperature conditions and then calculate the thickness required at the bottom head seam due to bending moments imposed by wind or earthquake forces. Stresses in the longitudinal direction are involved nod the following notation maybe […]
External pressure can be due to internal negative Pressure, or external loading like wind, earthquake etc. or live load, snow load etc. One can design Pressure vessel for either sever combination of various load or for most possible occurrence of load combination. Load combinations are given in respective ‘Building Code’ like API, UBC, IS etc. […]
We design pressure vessel for longitudinan and circumferencial stresses. Now whats that? Ok, longitudinal stresses comes on circumferencial joints, where as circumferencial stresses comes on longitudinal joints. And to add cherry on top circumferencial stresses are twise that of longitudinal stresses. If you are not yet twisted your tongue, and to avoid that we generally […]
OK.. The Billion dollar Question… Just to make it easy, we will break the pressure vessel in two category..1. Pressure Vessel without external loading &2. Pressure Vessel With external Loading For Category 1, we can use ASME Section VIII Div. 1 directly, where as for Category 2, we need to consider additional loadings. And for […]
Failure: Failure of a structure is an event, the transition from a normal working state, where the structure meets its intended requirements, to a failed state, where it does not meet its requirementsLimit states: A limit state is a structural condition beyond which the design performance requirements of a component are not satisfied. Limit states […]
Pressure vessels are probably the most widespread “machines” within the different industrial sectors. In fact, there is no factory without pressure vessels, steam boilers, tanks, autoclaves, collectors, heat exchangers, pipes, etc. More specifically, pressure vessels represent components in sectors of enormous industrial importance, such as the nuclear, oil, petrochemical, and chemical sectors. There are numerous […]
Now, let us start new topic, on design of pressure vessel! I think this one of the interesting subject, and we find lots of data over here and their defining how to design pressure vessel. Some people take advantage of this and confuse you some time.. end result you may get over size vessel (high […]
