It has long been thought by TIMET that hydrogen embrittlement cannot take place in titanium tubes in a power plant surface condenser because of the low steam temperature (about 40°C) and even lower metal temperature that exists in that environment. It has also been found that hydrogen embrittlement cannot occur in a medium where the pH is high and on the alkaline side as it is in a surface condenser. This opinion was based on work done both in TIMET laboratories and elsewhere; therefore, when titanium tubes were introduced in power plant condensers no specific laboratory work was performed to confirm the fact that hydrogen embrittlement could not take place.
