本文件规定了用于储存或处理水、市政或工业废水和污泥的搪瓷涂层螺栓圆柱钢储罐的设计和使用要求。 它适用于储罐和任何相关屋顶的设计，并为基础设计要求提供指导。 适用于以下情况: a） 所述罐是圆柱形的，并且安装在基本上处于或高于地面的承载底座上； b） 储罐直径（米）和壁高（米）的乘积在5到500; c） 储罐直径不超过100m，且总墙高不超过50m； d） 储存的材料具有液体的特性，在罐壁上施加可忽略的摩擦力；储存的材料可以作为市政或工业废水处理过程的一部分进行处理； e） 液体上方顶部空间的内部压力不超过50kPa，且液体上方的内部部分真空度不超过10kPa； f） 储罐的壁是垂直的； g） 储罐的底板在其与壁的相交处基本上是平坦的；储罐的底板可以有一个内置的上升或下降，以允许储罐内容物的完全排空，其斜率不超过1: 100; h） 由于储罐填充，惯性和冲击载荷可忽略不计； i） 储罐外壳的最小厚度为1.5毫米； j） 用于制造钢板的材料为碳钢（由铝或不锈钢制成的钢板制成的储罐不在本文件的范围内）； k） 操作期间罐壁的温度是否在该范围内50？°C至+100在所有操作条件下为°C。 本文件还详细说明了现场安装以及已安装储罐的检查和维护所需遵循的程序。 它不适用于化学品- 反应容器。 它不包括耐火性。

This document specifies the requirements for the design and use of vitreous enamel coated bolted cylindrical steel tanks for the storage or treatment of water or municipal or industrial effluents and sludges. It is applicable to the design of the tank and any associated roof and gives guidance on the requirements for the design of the foundation. It is applicable where: a) the tank is cylindrical and is mounted on a load-bearing base substantially at or above ground level; b) the product of the tank diameter in metres and the wall height in metres lies within the range 5？to？500; c) the tank diameter does not exceed 100？m and the total wall height does not exceed 50？m; d) the stored material has the characteristics of a liquid, exerting a negligible frictional force on the tank wall; the stored material can be undergoing treatment as part of a municipal or industrial effluent treatment process; e) the internal pressure in the headspace above the liquid does not exceed 50？kPa and the internal partial vacuum above the liquid does not exceed 10？kPa; f) the walls of the tank are vertical; g) the floor of the tank is substantially flat at its intersection with the wall; the floor of the tank can have a rise or fall built in to allow complete emptying of the tank contents, the slope of which does not exceed 1:100; h) there is negligible inertial and impact load due to tank filling; i) the minimum thickness of the tank shell is 1,5？mm; j) the material used for the manufacture of the steel sheets is carbon steel (tanks constructed of sheets made from aluminium or stainless steel are outside the scope of this document); k) the temperature of the tank wall during operation is within the range？50？°C to +100？°C under all operating conditions. This document also gives details of procedures to be followed during installation on site and for inspection and maintenance of the installed tank. It does not apply to chemical-reaction vessels. It does not cover resistance to fire.
