MATERIALS

Main Materials used in BEAUDREY Machines (water intake screens or condenser cleaning systems)

CARBON STEEL

  • Always used painted or lined. Ideal for structural purposes such as stoplogs, filter shells, bar racks, rotation screen structures etc.     

  • Cathodic protection is recommended in salt water.

  • High-tensile varieties are used for mechanical components.

 

AUSTENITIC STAINLESS STEELS

  • Good corrosion-resistance in fresh water (AISI 304L) or salt-water (AISI 316L). Very vulnerable to stagnant water and hydrogen sulfide (H2S).

  • Used for the same parts as carbon steel.

  • Unsuited for mechanical applications.

  • Easy to protect with cathodic protection.

​​

DUPLEX STAINLESS STEEL

  • Excellent corrosion resistance.

  • Very high tensile properties, can be used for all filter and screen components.

  • However, acceptable voltage range in the case of impressed current cathodic protection is very narrow, especially in combination with carbon steel.

 

SUPER-DUPLEX STAINLESS STEEL

  • Near-perfection corrosion resistance in seawater.

  • Very high tensile properties.

  • Very sensitive to impressed cathodic protection settings.

GLASS-REINFORCED POLYESTER (GRP)

  • Used for pipework, covers and guards.

  • Totally corrosion-free.

  • Other composites are used for NoclingTM mesh, rollers, jet nozzles, bushes and other fittings.
