储油罐主机包扩：（1）与第三方排水管对接焊接的第 几道环向金属接线头的坡口面;（2）外管螺纹接的第 一两个外管螺纹金属接线头横截;（3）活套蝶阀法兰对接的第 个活套蝶阀法兰封口面;（4）专用工具对接件又或者钢塑管对接的第 个封口面；（5）非压力强度电气元件与储槽的对接焊接。储存罐基座中的首要压力值管道部件收录罐顶、罐壁、罐底、公称直径约以上或相当250 mm的收回和管卡箍。储存罐的安会图片附件，收录进行设施在储存罐上的安会阀/心脏跳动阀、介质液体泄压阀、及时截断平衡安装、安会提供专业的平衡安装、压力值表、液位计、温度表计、阻火器等。卧式储油罐储油罐罐底板正常实际情况下实际情况下，罐底板仅起着传承成品油和罐权重力的用处，故正常底板刚板厚度在5mm以内。底板由刚板推广熔接而成。其相貌面与基本遇到，易发霉，内表面能又习惯性遇到成品油中的积聚的水汽和残渣，故而底板易接受侵蚀，再加上之不会检查报告和修理汽车，故而条件罐底板熔接后消防蓄水池，玻璃钢防腐方案好。卧式化工储罐化工储罐罐壁组成特殊性罐壁是由几层的圈板装配而成，各层圈板上的两端焊口均用连通，圈板与圈板直接的环向焊口则只能根据在使用需求应该连通，以成钢筋焊接。上、下圈板直接的陈列途径有交流互动行为式、套筒式、连通式和交织式。连通焊口在钢材板材的厚度等于6或大过6mm时，应该应开坡口，钢材钢筋焊接口处的极高应该为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.
