Duplex example of this is sluice gates , which regulate water flow in rivers and estuaries , where duplex is increasingly being adopted . Flood risks due to global warming require sluice gates that are taller and stronger . Industeel supplied 36 tonnes of duplex 2205 plate for eight sets of sluice gates across the river Couesnon near Mont St-Michel . The plate was used to clad the gates ’ coated carbon steel frame . The Slussen lock in Stockholm , Sweden , serves to protect the local population from flooding and separate drinking water from brackish water . It is located in a heavily travelled neighbourhood in the city centre . As part of a project to
widen the discharge canals , new sluice gates are being installed , made of 2205 duplex supplied by Outokumpu . They are larger than the gates they replace , allowing more water to be evacuated in the event of flooding . Also in Sweden , the rotten wooden sluice gates at Gårda Damme , Gothenburg , were replaced by five sluice gates built from Outokumpu ’ s 2404 duplex grade .
Conclusion We have seen that , when strength and resistance to extreme corrosion and high pressures are required , standard duplex and superduplex grades are increasingly seen as ideal , even indispensable ; and that in water management and architectural projects , standard and lean grades are becoming more popular . Duplex is also likely to become more mainstream as it is increasingly adopted for the 3D and WAAM manufacturing processes .
