This pressure vessel specification discusses general pressure vessel requirements including engineering design, fabrication, inspection, testing, painting, identification and marking, preparation for shipping and storage in compliance with the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1.
This specification will define the minimum acceptable requirements of unfired pressure vessels suitable for installation in energy industry.
This specification governs pressure vessels provided in accordance with the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1; pressure vessels, referred to as the ASME Code. Carbon steel vessels are generally limited to wall thickness of 1-1/2" (38 mm) or less and design temperatures of 6500F (3430C) or less.
This specification may be supplemented with other requirements such as vessel data sheets, Project Technical Requirements, Standard Drawings and/or other supplementary specifications (for vessels in specific services, such as three-phase separators).
The combined documents mentioned in this specification define the minimum acceptable requirements for the design, fabrication, inspection and testing of unfired pressure vessels suitable for installation in energy industry.
Buyer reserves the right to procure pressure vessels in accordance with the ASME Code even though they may be outside the formal scope of ASME Code, for instance due to size or pressure rating. Such pressure vessels should conform to all ASME Code requirements, except for application of the ASME Code Stamp and National Board Registration.
The most recent issue of the standards, specifications and codes (using the latest addenda issued through the date of this agreement) should be considered as a part of this Specification.
In addition to project technical requirements, pressure vessels should meet all requirements of the governmental authorities having jurisdiction at the location where the pressure vessels is to be installed, as stated in the Agreement, Contract, or Purchase Order, as applicable.
Vessels should be designed to meet the operating and design conditions listed on Vessel Data Sheets. Shell diameter, length and nozzle sizes shown are considered as minimum unless defined otherwise.
Vessels should be equipped with all attachments such as nozzles, manways, tray support rings, and insulation clips.
Supplier should be solely responsible for providing complete and operable pressure vessels in full accordance with all applicable industry codes and standards, government regulations and project technical requirements.
Written permission must be obtained before any work is subcontracted.
1.2 Conflicts and Exceptions
All conflicts between this specification or other technical requirements and the applicable codes and standards should be submitted in writing for approval.
