As the economy continues to recover, demand for titanium products remains strong
t is well known that titanium offers unrivalled corrosion and heat resistance. However, for cost reasons its use is usually reserved only for the severest applications. This article looks at two industries (aerospace and desalination) where titanium has proved competitive with other metals. In desalination, titanium is sought after for its unrivalled erosion, corrosion and heat resistance. In aerospace demand for a light, strong metal that is compatible with composites virtually guarantees a mar...
Titanium and super stainless steels for seawater cooled heat exchangers
Due to its outstanding resistance to general and localized corrosion, titanium continues to be the preferred material for seawater and brackish water-cooled heat exchanger tubing. However, cost-effective alternatives using highly alloyed stainless steels are available. Haydée Richaud-Minier, Gérard Pascal, Hervé Marchebois and Dennis Schumerth review the options....
Titanium in sea water: datasheet
Titanium and most of its alloys are highly resistant to stress corrosion cracking, (SCC) in sea water. Ti-6Al-4V ELI, (ASTM Grade 23) a variant of the most widely available alloy, will not exhibit SCC in either smooth or smooth notched components in sea water or brackish waters and is regularly selected for applications where high strength and corrosion resistance are required....
Titanium in seawater: one of the best performers
Titanium is one of the best performers for use in a corrosive seawater environment and is therefore often used for sheet heat exchangers. Nevertheless, with concerns about prices and delivery times, titanium is not usually regarded as the standard material for use in this type of environment. Jan Heselmans assesses whether this viewpoint is correct or not....
Titanium tube failures in Helifin® heat exchangers
In this technical paper, materials experts from Statoil discuss the failure analysis of heat exchanger tube leakages. The failure mode was concluded to be sliding adhesive wear of the tubes at the baffle plates caused by fluid induced vibrations of the heat exchanger's low finned titanium tubes. The failure mode was simulated in a laboratory test, and the tube vibrations were verified by theoretical calculations...
