Course Overview
Corrosion is a serious and expensive problem in engineering, and it is
estimated that it costs over 3% of the GDP of many developed countries.
However, in many instances, it is not considered during the design of
engineering components and structures. Aqueous corrosion in water systems is a
particularly serious problem, causing the breakdown and failure of piping and
equipment.
This course aims to give companies an understanding of corrosion in
water systems and the many different forms it can take. It will also show how
mechanical factors and the environment can interact, causing potentially
serious problems and failures.
The various methods of preventing corrosion, including material
selection and design, will be discussed, and this will allow you to select the
best methods of preventing serious problems.
Course Aims
The course aims to give you an understanding of corrosion and its
importance in water systems. It will allow you to identify problems and to
prevent them in the most economic and effective way. It will help you to
understand the problems encountered in the environment, which will help you in
the design stage before any potential failures may occur. It will also help you
to select the best and most economic methods of preventing corrosion and give
you a basic understanding of corrosion-resistant materials, which will help in
material selection and discussions with suppliers

Learning Outcomes
The course will enable companies to understand the importance of
corrosion and how it may be prevented in water systems. Attendees will:
- Gain an understanding of corrosion that will enable them to avoid
many potential problems.
- Be able to understand the basis of the galvanic series and how it
is used in material selection.
- Be able to identify the various forms of corrosion that affect
different water systems.
- Be able to understand how mechanical and metallurgical factors
affect corrosion and allow companies to avoid serious problems such as stress
corrosion cracking and hydrogen embrittlement.
- Understand and evaluate and understand the methods used for
corrosion prevention, which will allow people to select the best methods to be
used for their application.
Have knowledge of the most commonly used corrosion-resistant materials,
such as stainless steels. This will assist with material selection and help in
discussions with clients and suppliers.
Who should attend
The course is suitable for any company working in engineering or
manufacturing that requires a basic understanding of water systems and the
methods of preventing corrosion. It will be particularly useful for design and
production engineers as well as new starters and graduates.
