EQUIPMENT MAINTENANCE
Corrosion control aims
at ensuring the efficient
operation and upkeep of
physical assets.
even loss of life. A comprehensive corrosion
control policy is crucial to attain
and sustain the requisite levels of quality,
safety, and reliability within the
maintenance organization.
Effects of corrosion on Cranes
and Heavy Equipment:
The neglect of corrosion control measures
in industrial settings has led to tragic
outcomes, including loss of life, injuries,
significant economic losses, and severe
environmental damage. Corrosion has
been linked to numerous injuries and fatalities.
For instance, on March 15, 2009, a
50-ton hydraulic crane accident at a construction
site in New York City resulted
in the death of seven individuals. The hydraulic
crane, while hoisting a heavy load,
suddenly collapsed.
Investigations revealed that the
crane's right lifting cylinder had been
inadequately maintained, and corrosion
had weakened the lifting cylinders. Various
national studies conducted in several
countries over the past fifty years
have consistently estimated the costs
of corrosion to be around 3% to 4% of
each nation's Gross Domestic Product
(GDP). Considering a global GDP figure
of 3.4% (as of 2013), the estimated
worldwide cost of corrosion is a staggering
US$2.5 trillion. Another study, conducted
from 1949 to 1994, summarized
the economic losses resulting from corrosion
in the subsequent table.
Maintenance Solutions for
Corrosion Control:
Maintenance solutions aimed at controlling
corrosion are a crucial aspect of
industrial operations, ensuring the longevity,
safety, reliability, and efficiency
of heavy equipment and infrastructure.
By adopting effective corrosion
control practices, it is estimated that
significant savings, ranging from 15%
to 35% of corrosion-related expenses,
could be realized. This translates to
annual global savings of approximately
US$375 to $875 billion. These solutions
encompass a variety of strategies, from
protective coatings to predictive maintenance,
all aimed at mitigating the
destructive effects of corrosion. Implementing
effective maintenance solutions
not only protects valuable assets
but also minimizes economic losses,
environmental impacts, and potential
safety hazards. Below are the best industry
practices for maintenance solutions
against corrosion.
INTERNATIONAL STANDARDS
International standards are instrumental
in guiding corrosion control
and maintenance solutions for heavy
industrial equipment, providing a
universally recognized framework
that emphasizes consistency, quality,
and safety in practice. Below are
