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 […]
Hello All from Munich!Right now I’m at drinktec,and sharing my experience with you all.Drinktec (website : www.drinktec.com) Drinktec is an exhibition which happen at Munich germany after each 4 year! Its for people from Brewery & Beverages. The exhibitors are manufacturers & supplier from/ for same Industry.Its a good experience for new bee like me, […]
The differences have to be taken into consideration by both designer and welder. The high thermal expansionand low thermal conductivity of the austenitic steels lead to higher shrinkage stresses in the weld thanwhen carbon and ferritic steels are used. Thin sections of austenitic steels may therefore be deformed when an abnormally high heat input is […]
In pressure Part Industry we use various type of material. Typically in industry like this, we mainly classify material as Mild Steel also known as Carbon Steel, we also use low & high alloy steel & yes stainless steel! What diffrentiate staineless steel from Carbon steel is its corrosion resistance properties, whcih comes because of […]
