Maintenance
and Reliability

Prevent corrosion failures at each stage of design,
construction and normal operation
Each year, significant economic losses
Chemical and mechanical engineerdue
to corrosion failures occur in the refining
and petrochemical industries; unfortunately,
many of these losses could
have been prevented. Petroleum refining
today is unusually sophisticated compared
to the single-shell stills of the 1800s,
and the industry shows every indication
of becoming even more complex.

One result of these changes is a growing

titanium alloys-to cope with a wide variety
