Installation and maintenance:

Because the manhole is located in the lower part of the oil tank, the manhole bears a lot of liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. The flanges and cover plates are processed with sealing water lines, so care should be taken to protect them during construction to avoid oil leakage during use. Make a mark every time the manhole is removed to avoid dislocation when reinstalling, which affects the tightness. When installing the nuts on the manhole cover, apply force evenly in pairs to prevent oil leakage caused by deformation of the cover or uneven force.
