Analysis of Failure of Torispherical Head while Bending

[Purval Ashok Ganthade, Prof. N. P. Awate] Volume 2: Issue 2, June 2015
Abstract—Pressure vessels are the containers that are used in number of industries for the purpose of storage of fluids. Pressure vessels are used mostly in storage of gas (compressed or uncompressed), oils, pressurized liquids, molten metals, etc. and are utilized in nuclear,chemical and thermal plants too. For such multipurpose and tiresome work environment, it is of utmost importance to have a good quality boiler. Boiler plates are very popular for such conditions and environments. The advantages ofimplying a Boiler Quality steel is that life of the machine components and indirectly of the plant can be increased considerably, which in turn results in the increase in the safety and durability of structures, thus making them more reliable. It also helps in reducing the costs of repairing linked to the quality of Boilerand plant failure. The pressure vessel ends are regarded as the most important part as most pressure of the boiler is exerted on the ends. The weakening of such chief part may lead to very hazardous after-effects. So as to avoid the failure of the dish ends, precise steps to analyze are to be carried out as it will aid in defining the problems associated, and according solutions could be generated. The processes used for the proper bending of the plates are also to be optimized.
