CB/T615-1995 Shipbuilding -- Bilge suction grille
Marine sea - sea suction grille grille is mixed in the water in the
suction filter debris, to prevent debris blocking water heat
exchanger and lubricating oil heat exchanger, while avoiding debris
around the cooling water pump etc..

CB/T615-1995 marine suction grille - bottom suction grille -
submarine door grille - submarine door suction grille installation
methods and matters needing attention:
1: to consider practicality, that is, relatively smooth sea water
into the submarine valve box
2: next, consider the beauty, that is, to expose the outer part of
the plate as little as possible, and neat.
In the design stage of high low sea box as far as possible to avoid
online type over the place, also increased 50~100mm margin in the
border on the sea, in the sea after the end of the door frame
welding plate protruding place cut flat grid net circulation area
is greater than the sea water pipe
CB/T615-1995 suction grille for ships - bottom suction grille -
Marine submarine door grille - submarine door suction grille
strength test principle:
In the grille hole did not open to full size, from the temporary
opening into the submarine door, will be welded to the interior of
the submarine door, and then seal the opening. According to the
double bottom strength test requirements, test head from sea air
pipe height or the height of the limit line in the open deck,
general cargo limit line is below the freeboard deck of at least
76mm, so the hydraulic pressure test to vent pipe height.
