Flange cover opening
Thread Content
The flange cover of the reactor is 150. Now connect the 50mm pipe and directly drill holes in the flange cover, which is a bit like plate flat welding. Is it possible? If so, what is the maximum hole allowed in the flange cover? Also, if it is an enamel kettle, can holes be drilled?
If the hole is small, it is recommended to drill and weld a short pipe, which is safer.
No, the punched enamel is all broken.
Brother, which standard is this content taken from?
I also ask, where was this table cut from?* one time
The opening of the flange cover requires strength calculation and cannot be used as the opening.

Use SW6 to calculate the reinforcement of the flat cover opening. Try to see how much it can open. The maximum limit of openings allowed by the standard is found in the Equal Area Reinforcement Method 150, P152. Analytical methods with flat lids are not applicable. I am not familiar with other reinforcement methods.
