存储罐主机还包括:(1)与其他热力管道不锈钢焊接进行连接方式的第 第一道环向直线接头的坡口面;(2)螺牙进行连接方式的第 1个螺牙直线接头激光切割端面;(3)法兰盘片链接的第 某个法兰盘片隔绝盖面;(4)特用链接件又或者不锈钢管件链接的第 某个隔绝盖面;(5)非压力管道器件与卧式储罐的链接焊接缝。储槽主机中的注意耐压组件以及罐顶、罐壁、罐底、公称直径为低于或等于6250 mm的对接和管法兰部。储槽的可靠附加,以及直接的设计在储槽上的可靠阀/深呼吸阀、液滴泄压阀、应急中断安装、可靠加盟连锁安装、负担表、液位计、水温计、阻火器等。自然压贮罐罐底板常规具体情况下,罐底板仅起着传播油料和罐體重力的效果,故似的底板强度在5mm大于。底板由不锈钢钢板布设对接焊而成。其本身面与基础知识遇到到,轻松返潮,内外表面又习惯性遇到到油料中的火成岩的含水分和悬浮物,因为底板轻松感受到腐烛,加个之材质捡查和修剪,因为需要罐底板对接焊后没有渗漏,防水方式好。卧式玻璃钢罐玻璃钢罐罐壁构成特殊性罐壁是由许多层的圈板主装而成,一层的圈板上的垂直焊相接处隙均采用了交接,圈板与圈板范围内的环向焊相接处隙则按照采用特殊要求不错交接,也能够联结。上、下圈板范围内的摆列形式有可视化交互式、套筒式、交接式和相混式。交接焊相接处隙在不锈钢角钢壁厚相等于或超出6mm时,似的应开坡口,不锈钢角钢联结缝的程度似的为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.
