The course is designed to provide an in-depth perspective of heat exchanger technology in terms of maintenance and repair. We will also review heat transfer fundamentals as applied to tubular and plate devices. Built-in will be sessions on the practical aspects of shell and tube heat exchanger requirements in accordance ASME and TEMA codes.
Concluding this course, participants will identify and solve of a wide variety of industrial problems, using existing case studies. Systematic methods of inspection and maintenance will be thoroughly discussed, that can improve major problems such as fouling. Participants will understand the basic principles of heat transfer and fluid flow and their relation to the maintenance of shell and tube heat exchangers. Attention will be paid in TEMA and ASME codes in relevance to maintenance and repair issues. Additionally, the course will explain how poor maintenance and control affects Energy Balances in Heat Exchangers.
By the end of the course, participants will be able to:
Inspect, maintain and repair heat exchangers and evaluate their performance in the most professional way.
Distinguish between the numerous types of heat exchangers and acquire more knowledge of their industrial features and other relevant information and how the correct selection and operation affects proper maintenance.
Understand TEMA and ASME standards and terms for modern shell and tube heat exchangers
Define the overall effect of heat transfer coefficients on heat exchanger fouling
