Shell-and-tube heat exchangers are the backbone of the power generation, chemical process, petrochemical and pulp-and-paper industries. They are designed for a wide variety of services, from small-engine oil coolers to large nuclear steam generators. Heat exchangers come in many types and styles, but almost all are designed as unfired pressure vessels. Over the years, several industrial standards have been developed to help end users and manufacturers ensure that their heat exchange equipment will be designed with safety and consistency in mind. The principal reason why shell-and-tube heat exchangers have been so successful for so long is their ability to meet critical design performance objectives with such a wide variety of equipment configurations.
