Intertek is pleased to recognize Marvin Cohn, Director of Intertek Piping Asset Integrity Management, for his distinguished contributions to the industry. With more than 32 years of service to the ASME Boiler & Pressure Vessel Code and ASME B31.1 Power Piping Committees, Marvin has long been regarded as a leading authority in power piping integrity and performance. He is a recipient of the ASME Fellow (FASME) designation and is a recipient of the award Master of Power Piping by the ASME B31.1 Code Committee.
ASME PVP 2026 Conference, in Anaheim, California, July 19–23.
Marvin will be the Chairman of the Fitness‑for‑Service (FFS) session.
ASME B31.1 Piping System Performance Forum in Mesa, Arizona, September 2026.
Marvin will deliver a presentation titled "Asset Integrity Management of High Energy Piping Systems Operating Beyond 300,000 Hours" (date and time to be announced).
His presentation addresses a critical and increasingly visible industry challenge:
- A widening gap between ASME B31.1’s creep‑based allowable stress methodology and the extended service durations now required for aging fossil‑fuel power plant piping.
- The ASME B31.1 allowable stresses are derived from 100,000‑hour creep rupture data, yet many utilities are operating power piping systems for 300,000 to 500,000 hours, far beyond the design basis of the original allowable stress framework.
- This mismatch raises essential questions about long‑term reliability, risk management, and the need for updated engineering approaches as retirement timelines continue to shift.
Intertek celebrates Marvin Cohn’s continued leadership and technical vision as he helps shape the future of power piping integrity. His contributions at both the ASME PVP 2026 Conference and the ASME B31.1 Piping System Performance Forum underscore Intertek’s commitment to advancing engineering excellence, supporting industry innovation, and empowering utilities to meet the evolving demands of long‑life piping systems. Attendees can anticipate forward‑thinking insights that elevate understanding, spark collaboration, and drive meaningful progress across the global power generation community.
