MECHANICAL ENGINEERINGIntroduction
Heat exchanger is an important and expensive item of equipment that is used almost in every industry (oil and petrochemical, sugar, food, pharmaceutical and power industry).A better understanding of the basic principles of heat transfer and fluid flow and their application to the design and operation of heat exchangers that you gain from this course will enable you to improve their efficiency and extend their life. You understand how to use the applicable API, TEMA and ASME recommended practices, standards and codes for heat exchangers. This will enable you to communicate with the designers, manufacturers and bidders of heat exchangers. You will understand how to avoid fouling, corrosion and failure and leak problems by your design. You will also be able to survey and troubleshoot heat exchangers and assist in performing inspection, cleaning, and maintenance. You will be exposed to recent development and future trend in heat exchangers.
Objective
Audience
Project engineers, process engineers and plant engineers in the oil, chemical, sugar, power, and other industries who requires a wider and deeper appreciation of heat exchangers design, performance and operation. The detailed review of thermal and mechanical design is particularly useful to plant and maintenance engineers as well as to those generally knowledge able in the subject, but who require a refresher or update.
Codes and standards are useful for project engineer to help him communicate with manufacturers, designers and bidders of heat exchangers. Troubleshooting procedures are important for process engineers.

MAESTRO CONSULTANTS Certificate of Completion for delegates who attend and complete the training course
Methodology
Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
