卧式储罐本体比如：（1）与 外部线路悍接接入的第 道环向线金属接头的坡口面;（2）外螺纹标准接入的第 一两个外螺纹标准线金属接头内孔;（3）法兰片部连到的第 一款法兰片部封密面;（4）专用的连到件或钢塑复合管连到的第 一款封密面；（5）非压力强度组件与储槽的连到焊接件。罐体完整性中的主要学习压力强度构件包含罐顶、罐壁、罐底、公称半径超过或值为250 mm的对接和管蝶阀法兰。罐体的的安全防护防护超大附件，包含可以设定在罐体上的的安全防护防护阀/气息阀、流体泄压阀、紧急措施截断配置、的安全防护防护连锁品牌配置、学习水表、液位计、温度表计、阻火器等。卧式化工储罐化工储罐罐底板普通 环境下，罐底板仅起着转递化学品和罐身高力的影响，故常见底板薄厚在5mm这些。底板由厚钢板推广悍接而成。其表层面与根基碰到，易于发潮，内外壁又一般碰到化学品中的沉淀的水和杂质残渣，那么咧底板易于遭遇蚀化，多加之难于检验和清洗，那么咧规范要求罐底板悍接后渗漏，防腐涂料保障措施好。卧式化工储罐化工储罐罐壁设计作用罐壁是由指导意见层的圈板安装而成，一层的圈板上的垂直于合作焊道均所采用合作，圈板与圈板左右的环向合作焊道则跟据选择追求能能合作，可以锚固。上、下圈板左右的编排方式方法有交互式式、套筒式、合作式和分层式。合作合作焊道在钢条板材厚度相等或低于6mm时，一样 应开坡口，钢条锚固缝的较高一样 为6~8倍板厚，常取35~60mm。The tank body includes: (1) the groove surface of the first circumferential joint welded with the external pipeline; (2) The end face of the first threaded joint of the threaded connection;(3) The first flange sealing surface of flange connection; (4) The first sealing surface connected by special connectors or pipe fittings; (5) Connection weld between non pressure bearing components and storage tank.The main pressure bearing components in the tank body include tank top, tank wall, tank bottom, connecting pipe and pipe flange with nominal diameter greater than or equal to 250 mm. The safety accessories of the storage tank include the safety valve/breather valve, liquid pressure relief valve, emergency cut-off device, safety interlock device, pressure gauge, liquid level gauge, thermometer, flame arrester, etc. directly installed on the storage tank.Bottom plate of atmospheric storage tankUnder normal circumstances, the bottom plate of the tank only plays the role of transferring oil products and tank gravity, so the thickness of the bottom plate is generally more than 5 mm. The base plate is laid and welded by steel plates. Its outer surface is in contact with the foundation, which is easy to get damp, and its inner surface is often in contact with the water and impurities deposited in the oil, so the bottom plate is easy to be corroded. In addition, it is not easy to check and repair, so it is required that the tank bottom plate should be free of leakage after welding, and the anti-corrosion measures should be good.Structure characteristics of atmospheric tank wallThe tank wall is assembled by several layers of ring plates. The vertical welds on each layer of ring plates are butt welded. The circumferential welds between the ring plates can be butt welded or overlapped according to the use requirements. The arrangement modes between the upper and lower ring plates are interactive, sleeve type, butt joint type and hybrid type. When the thickness of butt weld steel plate is equal to or greater than 6mm, the groove shall be generally made. The height of steel plate lap joint is generally 6-8 times the plate thickness, usually taking 35-60mm.
