储油罐本体以及:(1)与间接排水管道手工焊接对接的第 一扇环向金属直接头的坡口面;(2)螺孔对接的第 另一个螺孔金属直接头激光切割端面;(3)活套蝶阀法兰连结的第 个活套蝶阀法兰封严性能面;(4)用连结件或许钢管扣件连结的第 个封严性能面;(5)非压力强度零件与储槽的连结对接焊缝。储存罐本体论中的大部分耐压电子器件比如罐顶、罐壁、罐底、公称厚度少于或=250 mm的移交和管法兰片。储存罐的可靠配件,比如随时设立在储存罐上的可靠阀/享受阀、全自动泄压阀、紧急措施打断平衡装制、可靠直营平衡装制、负荷表、液位计、热度计、阻火器等。自然压储存罐罐底板正确情况下下,罐底板仅起着传输化学品和罐斤算力的效应,故一般来说底板体积尺寸在5mm上。底板由刚板摆设对焊而成。其样貌面与框架接觸,比较方便吸潮,内外面又常接觸化学品中的沉淀积累的人体水分和溶物,因此说底板比较方便给予蚀化,加个之不会轻易常规检修修剪,因此说的要求罐底板对焊后没有渗漏,防腐蚀处理好。卧式存储罐存储罐罐壁设计特性罐壁是由若干意见层的圈板按装而成,各楼层圈板上的垂直管道焊接均采用了协同工作,圈板与圈板相互左右的环向管道焊接则会根据采用的要求能能协同工作,即可钢筋搭接。上、下圈板相互左右的排列三方式有互交式、套筒式、协同工作式和搅拌式。协同工作管道焊接在角钢壁厚等同于或超出6mm时,通常应开坡口,角钢钢筋搭拼缝的程度通常为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.
