PIP VECV1001

Note to Readers: This Practice contains design criteria for pressure vessels and shell-and-tube heat exchangers. Corresponding subject matter for pressure vessels and shell-and-tube heat exchangers is covered by paragraphs identically numbered. Paragraphs pertaining to pressure vessels are preceded by [V]. Paragraphs pertaining to shell-and-tube heat exchangers are preceded by [E]. Paragraphs pertaining to both are preceded by [V/E]. In addition, ASME Boiler and Pressure Vessel Code, Section VIII, Division 2 requirements are shown in braces { }.

This Practice should be used for pressure vessels built to Division 1 or Division 2 of the ASME Boiler and Pressure Vessel Code, henceforth referred to as the Code. Shell-and-tube heat exchangers are limited to Division 1 in this Practice.

[V] The primary focus of this Practice is to communicate vessel design criteria and methodology from the User to a Designer. This Practice is also intended as guidance for the development of purchase specifications covering the construction of new pressure vessels which meet the philosophy and requirements of Section VIII, Division 1 {or 2} of the Code.

[E] The primary focus of this Practice is to communicate vessel design criteria and methodology from the User to a Designer. 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 of the Code and TEMA Standards of the Tubular Exchangers Manufacturers Association.

[V/E] This Practice must be used in conjunction with PIP VEDST003, PIP VEDV1003, PIP VEFV1100, and PIP VESV1002 in order to comprise a complete vessel purchase specification.

[V/E] 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 vessel geometries. Accordingly, provisions of this Practice may be overridden or supplemented by an Overlay Specification.

[V/E] Standardized pre-designed (off-the-shelf) vessels and heat exchangers are not within the scope of this Practice but are covered in PIP VESSM001.
