scope:

This Practice must be used in conjunction with PIP VEDST003, and PIP VEFV1100 (applicable details), in order to comprise a complete heat exchanger purchase specification.

Many recognized and generally accepted good engineering construction practices are included herein. However, in light of the many diverse service applications of Code vessels, these practices must be employed with engineering judgment and supplemented as appropriate with requirements related to specific materials of construction, service fluids, operating environments, and heat exchanger geometries. Accordingly, provisions of this Practice may be overridden or supplemented by an Overlay Specification.

Standardized pre-designed (off-the-shelf) heat exchangers are not within the scope of this Practice, but are covered in PIP VESSM001.

Heat exchangers with layered construction are outside the scope of this Practice.

Purpose

The primary focus of this Practice is to communicate heat exchanger design and fabrication criteria and methodology from the User to a Designer and/or the Manufacturer. This Practice is also intended as guidance for the development of purchase specifications covering the construction of new shell-and-tube heat exchangers which meet the philosophy and requirements of Section VIII, Division 1 {or 2} of the Code and TEMA Standards of the Tubular Exchangers Manufacturers Association.
