This Practice provides data forms and the associated instructions for specifying requirements 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 Code, Section VIII, Division 2 are shown in braces .This Practice is used with PIP VECV1001 and VESV1002 to specify information necessary for the manufacturer to design and fabricate a pressure vessel.

This Practice supplements API 650, Welded Steel Tanks for Oil Storage. Together, this Practice and API 650 provide requirements for the construction of atmospheric storage tanks.This Practice and API 650 describe minimum construction requirements for the materials, design, fabrication, erection, examination, and testing of aboveground, non-refrigerated storage tanks. This Practice describes additions and modifications made to API 650. In addition, this Practice describes decisions made regarding options offered by API 650. This Practice supplements, but does not supersede, API 650 and any applicable jurisdictional requirements.This Practice covers storage tanks that have design internal pressures of 17.2 kPa (2.5 psig) or less (see API 650, Annex F) and design temperatures less than 260°C (500°F) (see API 650, Annex M).This Practice presumes the use of the API 650 Data Sheet to cover the requirements in API 650, and the Data Sheet, as a supplement, to define the additional requirements of this Practice.

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 Code, 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 VECSP001 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 PIPVESV1002. If Purchaser also performs a detailed design, the design shall also be in accordance with PIP VESV1002.The following are not covered by this Practicea. Standardized pre-designed (i.e., off-the-shelf) vessels (see PIP VESSM001)b. Vessels with layered constructionc. Small vessels and low-pressure vessels (see PIP VESSM001 and PIP VESLP001)d. Process design of trays and other removable internals

This Practice provides requirements for the design, materials, fabrication, examination, inspection, testing, certification (ASME stamp and Supplier’s Data Report), and pressure relief of aboveground fiberglass reinforced polyester, vinyl ester, and epoxy tanks and vessels having internal or external pressure from full vacuum up to the limits of Code Section X.
