Stainless steel round manway C93 (DN370)
Stainless steel round manway C93 is installed in the roof of the stainless steel tank. Its removable cover is fixed to the frame with four handwheels. What's more, the flat area on the cover allows for the installation of additional accessories (for example: sight glass or breathe valve).
Model C93 is produced as standard with mounting frames (flanges) of 60 mm or 90 mm height (see table). Optionally, it is possible to equip the manway with a frame of up to 200 mm height. As a result, it is possible to install the manway in stainless steel tanks covered with thermal insulation.
The round manway C93 is generally installed in stainless steel tanks designed for storing various types of liquid products, but it can also be successfully used in a variety of process equipment.
As standard, the C93 manway is manufactured from AISI 304 grade stainless steel, and optionally from AISI 316L. A wide range of gasket materials allows the manway to be used in contact with a variety of working media (liquids).
