PIP VECV1001 – Design Criteria and Purchasing Requirements for Vessels ASME Code Section VIII, Divisions 1 and 2 [Technical Correction]

This Practice provides requirements for use by a Purchaser for determining the design criteria for pressure vessels constructed in accordance with ASME Boiler and Pressure Vessel Code Section VIII Division 1 or Division 2, henceforth referred to as the Code. Requirements that are specific to ASME Section VIII Division 2 are shown in braces { }.

This Practice describes the requirements for the design, materials of construction, inspection and testing of pressure vessels constructed in accordance with Code, Section VIII, Division 1 {or 2}. Guidance is also provided for the development of purchase specifications for the construction of new pressure vessels which meet the philosophy and requirements of Code, Section VIII, Division 1 {or 2}.

This Practice also applies to bulk solids product containers, electric immersion process heaters, shell and plate exchangers, shell and tube exchangers, and air-cooled exchangers. See PIP VECBI001 and PIP VESBI002 for the additional requirements specific to bulk solids product containers only. See PIP VESEH001 for the additional requirements specific to electric immersion process heaters. See PIP VECSP 001 and PIP VESSP002 for the additional requirements specific to shell and plate exchangers only. See PIP VECST001 and PIP VESST002 for the additional requirements specific to shell and tube exchangers only. See PIP VESAC001 for the additional requirements specific to air-cooled exchangers only.

This Practice is intended to be used for the purchase of vessels where the Manufacturer is also responsible for performing detailed design for the vessels in accordance with the Code and PIP VESV1002. If Purchaser also performs a detailed design, the design shall also be in accordance with PIP VESV1002.

The following are not covered by this Practice:
a. Standardized pre-designed (i.e., off-the-shelf) vessels (see PIP VESSM001)
b. Vessels with layered construction
c. Small vessels and low-pressure vessels (see PIP VESSM001 and PIP VESLP001)
d. Process design of trays and other removable internals
