As illustrated in the write-ups on Titanium and Duplex, Welders N.V. has accumulated a wealth of experience in the design, engineering and construction of tubular heat exchangers using seawater or brackish water as cooling medium, both for new projects or for retrofitting.

In addition to Titanium and Duplex, which are emerging as the current materials of choice, this expertise extends to Copper-Nickel, Super Austenitic Stainless Steels and Nickel-based alloys, usually Monel or Hastelloy C276.

Welders N.V. has supplied hundreds of heat exchangers, coolers, heaters and condensers using seawater, notably in the Middle East and in South East Asia, where treated water is scarce or unavailable for many applications, particularly in :

• Off-shore platforms 
• Heavy oil treatment
• Gas processing 
• Refineries 
• Downstream industries : Petrochemicals, Chemicals, Fertilizers

Welders is in a unique position to meet virtually any sea water corrosion challenge in heat exchangers.
