Maintain Heat Exchanger- Fundamental

Maintain Heat Exchanger- Fundamental
Duration 5 Days
Introduction This Heat Exchangers training course will present the technical and operational features of Heat Exchangers of various designs (shell-and tube (STHE), air-cooled (ACHE), plate (PHE) that play a vital role in thermal power plants and petrochemical and process industries. It has been realized that Engineers of diverse backgrounds and expertise need to develop a sound understanding of fundamental principles and interrelationship between various parameters that govern the well designed and operated heat exchangers.
Objectives By the end of this course, the trainee will be able to:

–          State the various types of different Heat Exchanger.

–          Explain the operating parameters of the Heat Exchanger.

–          Heat Exchangers Design Characteristics

–          Understanding of Heat Transfer principles

–          International Codes and Standards for fabrication, operation and maintenance

–          Problems in operation: Fouling and performance monitoring

–          Inspection of corrosion, erosion and structural integrity

–          Explain the use of the various types of application of heat exchanger.

–          Explain the main hazards and risks when working on Heat Exchanger.

–          Demonstrate how to select the Heat Exchanger.

–          Demonstrate how to start up, Tests and shutdown Heat Exchanger.

–          Demonstrate proper inspection and maintenance of Heat Exchanger.

Audience This course designed for:
