储存罐本身其中包括：（1）与外界给水管对焊连到的第 这道环向插头的坡口面;（2）管螺纹标准连到的第 一种管螺纹标准插头外圆;（3）活套法兰部链接的第 这个活套法兰部抽真空带面;（4）专业链接件以及管道配件链接的第 这个抽真空带面；（5）非耐压pcb板与玻璃钢罐的链接焊道。罐体精神力中的最主要的负压强度开关元件有罐顶、罐壁、罐底、公称厚度超过或相当于250 mm的打压和管卡箍。罐体的健康应急的有附件，有一直布置在罐体上的健康应急的阀/感受不到阀、介质泄压阀、急忙关闭保护试验装置、健康应急的品牌连锁保护试验装置、负压表、液位计、室内温度器、阻火器等。自然压卧式储罐罐底板通常具体情况下，罐底板仅起着传送汽柴油和罐权重力的用处，故通常底板它的厚度在5mm以上的。底板由角钢装修电焊焊结而成。其表层面与根基触碰，比较易于起霉，内从表面又总是触碰汽柴油中的的堆积的水分侵入和其它杂物，之所以咧底板比较易于感受到浸蚀，加上之材质检测和修复，之所以咧条件罐底板电焊焊结后消防蓄水池，防蚀工作好。卧式罐体罐体罐壁构造优点罐壁是由若干意见层的圈板折装而成，第一层圈板上的竖向焊缝口隙均适用挂接，圈板与圈板间的环向焊缝口隙则随着选用规范要求能能挂接，苟有钢筋搭接。上、下圈板间的陈列方法有交互式式、套筒式、挂接式和搭配式。挂接焊缝口隙在厚钢板材料宽度等于6或达到6mm时，一样 应开坡口，厚钢板材料钢筋搭缝口的层面一样 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.
