标准范围

ISO 28765:2008规定了用于储存或处理水或市政或工业废水和污泥的搪瓷涂层螺栓圆柱形钢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，并为基础设计的要求提供指导。它适用于储罐是圆柱形的，并且安装在基本上位于或高于地面的承载基座上；以米为单位的储罐直径与以米为单位的壁高的乘积在5至500的范围内；罐体直径不超过100 m，总壁高不超过50 m；储存的物料具有液体的特性，对罐壁施加可忽略的摩擦力；储存的材料可以作为市政或工业流出物处理过程的一部分进行处理；液体上方的顶部空间中的内部压力不超过50kPa，并且液体上方的内部部分真空不超过10kPa；罐壁是垂直的；罐的底板在其与壁的相交处基本上是平的；储罐的底板可以具有内置的上升或下降，以允许完全排空储罐内容物，其坡度不超过1:10 0；由于油箱填充，惯性和冲击载荷可以忽略不计；罐壳最小厚度为1.5 mm；用于制造钢板的材料是碳钢（由铝或不锈钢板制成的储罐不在本国际标准的范围内）；在所有操作条件下，操作期间罐壁的温度在-50℃至+100℃的范围内。该国际标准还详细说明了现场安装以及检查和维护已安装储罐时应遵循的程序。它不适用于化学反应容器。它不适用于装有浮顶的储罐。它不包括耐火性。

ISO 28765:2008 establishes 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 applies to the design of the tank and any associated roof and gives guidance on the requirements for the design of the foundation.It applies where

1. the tank is cylindrical and is mounted on a load-bearing base substantially at or above ground level;
2. the product of the tank diameter in metres and the wall height in metres lies within the range 5 to 500;
3. the tank diameter does not exceed 100 m and the total wall height does not exceed 50 m;
4. the stored material has the characteristics of a liquid, exerting a negligible frictional force on the tank wall; the stored material may be undergoing treatment as part of a municipal or industrial effluent treatment process;
5. 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;
6. the walls of the tank are vertical;
7. the floor of the tank is substantially flat at its intersection with the wall; the floor of the tank may have a rise or fall built in to allow complete emptying of the tank contents, the slope of which does not exceed 1:100;
8. there is negligible inertial and impact load due to tank filling;
9. the minimum thickness of the tank shell is 1,5 mm;
10. 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 International Standard);
11. the temperature of the tank wall during operation is within the range -50 °C to +100 °C under all operating conditions.

This International Standard 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 apply to tanks fitted with floating roofs.It does not cover resistance to fire.
