Manhole on the bottle
Thread Content
For a certain project, it involves a small tank with a diameter of 800 mm and a height of one meter; the equipment diagram shows that there is an access hatch provided. Are you planning to use a robot in there, or are you trying to perform some magic tricks or escape room games?

With a diameter of 800, the diameter of the manhole/handhole designated for use must not exceed 400; in that case it is no longer a manhole, and can be called a handhole
For this device labeled as a \"small tank\", it is necessary to determine whether the manhole provided is appropriate and compliant. First, consider its function: does it qualify as a pressure vessel? Is it classified as such under the \"Safety Technical Specifications for Boiler Design TSG G0001\"? Then it’s better to discuss whether it complies.
For small containers at atmospheric pressure, it is essential to design manholes when inspections and cleaning operations are necessary.
I don’t understand why there is such a question? It facilitates internal inspections; what’s wrong with installing manholes?

“It is advisable to give priority to handholes or inspection holes”; it’s also fine to use manholes. It depends on the intended use.
