"Marine International Shore Connection - Oil Wastewater Discharge Connection" Product Overview



Marine Domestic Sewage International Shore Connection CB3657-2011





This oil wastewater international shore connection and domestic sewage international shore connection are mainly used in ship oil wastewater and domestic sewage pipeline systems. One end is a flat flange, and the other end is an attached interface that matches the ship's fire hydrant and fire hose; the international shore connection interface is consistent with the ship's own fire hydrant and hose interface.



All ships must be equipped with at least one international shore connection. Its function is: when the ship's fire pump fails, the CB3657-2011 international shore connection is used to introduce fire water from shore or other facilities into the ship's fire-fighting pipeline system to continue firefighting.
