Type, basic parameters and dimensions
450X350
Note: ① The height of the manhole is 200. If there are special requirements, it can be changed, but the height dimension after the change must be noted and the wall thickness of the cylinder section must be rechecked. If it cannot meet the requirements, the wall thickness should be increased, and the stainless steel mass and total mass of the manhole should be modified.
② The mass of the manhole is 69kg for carbon steel and 22.66kg for stainless steel; the total mass is 92kg. ③ The type of the sealing surface is a raised surface.
