Shell & Tube Heat Exchangers


Course Description:


The course concentrates on heat exchanger hardware, performance requirements, inspection, maintenance and repair, and life extension. The material applies to tubular exchangers used in chemical and petrochemical plants, oil refineries, power stations and industrial facilities. Thermal design is not discussed except where it affects the structure. The TEMA system which is,  Internationally used explained for describing size and type. TEMA nomenclature and terminology are illustrated.


The ASME code and TEMA standards are observed. Design point setting which effects the structure of the operating deviations, transients and upsets are examined. An overview of tube vibration includes descriptions and illustrations of damage caused by tube vibration, vibration forcing mechanisms and information required for vibration analysis.    



Learning Objectives:


The program is designed to giver the participants a understanding of the nomenclature and terminology used for shell and tube heat exchangers, how the tube side and shell side of tubular heat exchangers are constructed, how heat exchangers are structured, assembled, manufactured, preparation for installation and joined to tube sheets. It also will cover how to write and interpret specifications, some of the exchanger codes and standards, inspections, maintenance, repair and inspection techniques and determination of failure causes.



Who Should Attend:


The program is aimed at personnel, who are involved with procurement,

construction, installation, inspection and trouble shooting, also with maintenance,

repair, mechanics, operation and life expectancy of shell and tube heat

Exchangers. The program will also be of special value to individuals who specify or buy heat exchangers or who are in charge of evaluating the condition of existing equipment.
