【正文】 G PROCESS ABSTRACT Liquefied petroleum gas storage tank is holding mon equipment of liquefied petroleum gas (LPG), due to the characteristics of the gas is flammable and explosive, so in the design of the storage tank, to pay attention to the differences and mon gas storage tank, especially for security and fire prevention, note also that in the aspect of manufacture, installation, tank design is based on stress analysis as the main way, on the basis of mechanics of materials, to design the main pression portion of the container. Its design purpose is mainly to determine the reasonable, economic structure, and satisfy the fabrication, inspection, assembly, transportatio n and maintenance requirements, mainly from two aspects of strength and stiffness in the design of design to ensure container does not leak due to transition of deformation failure, eventually reached the requirements of safe and reliable work performance. The liquefied oil tank based on GB150, JB/T4732 Design standards, strict enforcement of TSG R00042020 stationary pressure vessels safety technology supervision procedures provisions, give full consideration to saving energy and reducing consumption, based on the elastic failure criteria (Design by Rule), and plete Design of LPG storage tank。洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)（論文） I 畢業(yè)設(shè)計(jì)（論文） 38m 3液化石油儲(chǔ)罐結(jié)構(gòu)工藝及焊接工藝設(shè)計(jì) 摘 要 液化石油氣貯罐是盛裝液化石油氣的常用設(shè)備 ， 由于該氣體具有易燃易爆的特點(diǎn) ， 因此在設(shè)計(jì)這種貯罐時(shí) ， 要注意與一般氣體貯罐的不同點(diǎn) ， 尤其是安全與防火 ， 還要注意在制造 、 安裝等方面的特點(diǎn)。 該液化石油儲(chǔ)罐依據(jù) GB150、 JB/T4732等設(shè)計(jì)標(biāo)準(zhǔn)、嚴(yán)格執(zhí)行 TSG R00042020《固定式壓力容器安全技術(shù)監(jiān)察規(guī)程》的規(guī)定，充分考慮節(jié)能降耗的要求，基于彈性失效準(zhǔn)則，完成對(duì)液化石油氣儲(chǔ)罐的設(shè)計(jì)；在 AUTOCAD 中正確繪出裝配圖；以?xún)?chǔ)罐的 建模，分析儲(chǔ)罐整體的 應(yīng)力，數(shù)據(jù)顯示在人孔接管與殼體連接處發(fā)生應(yīng)力集中，同時(shí)經(jīng)過(guò)查閱資料，運(yùn)用公式也證明了只有人孔接管需要補(bǔ)強(qiáng)；然后對(duì)該儲(chǔ)罐進(jìn)行了補(bǔ)強(qiáng)設(shè)計(jì)。 Then has carried on the reinforcement to the tank design.
