Flange Type Deck Scupper
Flange Type Deck Scupper is a marine drainage fitting designed with a flanged connection for collecting and discharging rainwater, seawater, and other liquids from ship decks.
The flange connection allows the scupper to be securely installed on ship decks and connected with drainage pipelines through bolts and gaskets, providing reliable sealing performance and convenient maintenance.
Flange Type Deck Scupper is commonly installed in:
Main deck drainage systems
Weather decks
Cargo decks
Superstructures
Offshore platforms
Marine engineering structures
Overview
Working Principle of Flange Type Deck Scupper
Flange Type Deck Scupper works as a connection point between the ship deck drainage area and the drainage pipeline system.
Operating Process:
Rainwater or seawater accumulates on the deck surface.
Water enters through the scupper inlet.
The scupper body guides water into the connected drainage pipe.
The flange connection transfers water safely through the pipeline system.
Water is discharged overboard or into the vessel drainage system.
