About the design of DN6000 pressure vessel ear supports
Thread Content
Dear friends, how to calculate the ear support of a pressure vessel with a design nominal diameter of 6000mm, a design temperature of 350°C, and a design pressure of 0.4MPa? P.S.: The new version of the container support specifications only covers a temperature of 300°C and a nominal diameter of 4000mm. The calculations behind the standard interpretation are not understandable. Please * * Give advice
The diameter is DN6000, which is beyond the scope allowed by the standard. If I were to design this device, and if the conditions required an ear-type support, then I might make a circle of reinforcement plates around the ear-type support. Let this circle of barrel bear the load. As for how many supports you need, you have to calculate it. You can calculate it using standard calculation methods. The above opinions are for your reference only.
You upload the parameters to me, mainly the operating weight of the equipment.
DN6000 is not suitable for ear-mounted use.
The ear mounts may not be suitable, so it is recommended to use rigid rings
Is there a requirement for the distance between the bottom plate of this support and the end of the barrel? (Using the components in SW6 to calculate the local stress of the cylinder requires that the distance from the base plate of the support to the tangent line of the head (or the end of the shell) should be greater than half of the cylinder radius, which is also required in chemical design)
Calculate the support reaction force according to HGT 20582-2011 "Regulations on Strength Calculation of Steel Chemical Vessels" P253. The distance between the support bottom plate and the end of the cylinder is not less than half of the average radius of the cylinder. The customer requires the support to be placed at the end of the cylinder (as shown in Figure 2). How to calculate it?
