卧式储罐本体包涵：（1）与内部管网不锈钢焊接相连的第 一步环向进行连接管的坡口面;（2）螺孔相连的第 同一个螺孔进行连接管横截;（3）卡箍盘链接的第 一些卡箍盘封闭面;（4）专属链接件或是管链接的第 一些封闭面；（5）非压力强度电子器件与卧式储罐的链接对接焊缝。储存罐本体论中的主耍经济压力管道pcb板涉及到罐顶、罐壁、罐底、公称内直径不超或相等于250 mm的对接和管法兰部。储存罐的可靠配件，涉及到可以設置在储存罐上的可靠阀/透气阀、固态泄压阀、紧急情况割断安全保障配置、可靠連鎖安全保障配置、经济电接点压力表、液位计、环境温度表、阻火器等。卧式卧式储罐卧式储罐罐底板通常具体情况下，罐底板仅起着表达油号和罐斤算力的影响，故正常底板规格在5mm这。底板由铝合金板铺装锡焊而成。其相貌面与基础理论触碰，简易吸潮，内漆层又定期触碰油号中的沉淀的含水量和悬浮物，故此底板简易给予防腐涂料蚀，加上之不宜檢查和維修，故此请求罐底板锡焊后渗漏，防腐涂料处理好。卧式罐体罐体罐壁成分优缺点罐壁是由指导意见层的圈板按装而成，每一层圈板上的垂直焊接均用到接管，圈板与圈板间的环向焊接则选择在使用规范要求是可以接管，若为套筒连接。上、下圈板间的布局模式有人机交互式、套筒式、接管式和混合式式。接管焊接在不锈钢角钢规格等同于或大于等于6mm时，一样 应开坡口，不锈钢套筒连缝口的宽度一样 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.
