Pressure Vessel Research Council

About PVRC

The Pressure Vessel Research Council (PVRC) is part of the not-for-profit Welding Research Council, Inc. (WRC). PVRC was formed as part of the  WRC in 1945 to continue the mode of cooperative research begun during World War II. Its goal was to coordinate and extend research on various aspects of pressure vessel technology under the direction of industry volunteer committees.

Activities in PVRC have included:

  • Bolted flanged connections
  • Dynamic analysis and testing
  • Elevated temperature design
  • Fatigue and fracture
  • Piping, nozzles and vessels, plastic analysis
  • Failure modes of components
  • NDE
  • Weld metals and welding procedures
  • Flaw evaluation
  • Continued modernization of codes

Results of research and development are published in WRC Bulletins. Usually, 10  bulletins are published in a year. Bulletins are enduring reference documents on technical issues such as Design and Fitness-for-Service Code Criteria. WRC has published more than 500 Bulletins to date, all of which may be purchased on this website.

Much of PVRC's research supports Codes and Standards activities, such as those of ASME, API, ASTM, and TEMA. PVRC Committees are staffed with participants from the industry, research laboratories, universities, and standards organizations. Research is conducted by project investigators under the direction of ad hoc industry-oriented volunteer committees. The responsible committee provides technical guidance. Approval is attained by a consensus voting process. This volunteer mechanism for conducting research fosters valuable networking among members — a significant value of membership in PVRC. Being a member of PVRC provides the opportunity for early knowledge and influence over technology development.

PVRC offers conferences on timely subjects, and are open to the public.
