A sanitary manhole should be set near the right side of the oil inlet and outlet pipe, and the manhole should be closed to the tank room as far as possible, so as to facilitate personnel access, maintenance of oil tank and ventilation pipe connection.

Because the manhole is installed on the lower body ring of oil tank, it is very important to prevent leakage. It is required to ensure the straightness of the joint surface of the two flanges without drift and torsion.


 Manhole


The reinforcing plate and flange shall be cut on the whole steel plate as far as possible without splicing.
