scope:

This Practice shall be used in conjunction with PIP VEDV1003 and/or PIP VEDV1003_EEDS, PIP VEFV1100 (Applicable Details), and PIP VESV1002 in order to comprise a complete vessel 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 shall 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.

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

Vessels with layered construction are outside the scope of this Practice.

Purpose

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.
