BJRS 2019 Bolted Joint Reliability Symposium

Norris Conference Center, Houston, Texas

Conference: October 1 – 3, 2019
Exhibition: October 1 – 2, 2019



The ASME PVP Bolted Joint Reliability Symposium (BJRS) promotes knowledge sharing, technological progress and international co-operation for advancing bolted Joints and sealing technology for the pressure vessel and piping industry. The presentations will disseminate the scientific and real-world knowledge in the area of bolted joints, including current and future design rules for bolted flange connections based on tightness (ASME SWG-BJ, EN1591), modern flange assembly guidelines and best practices (ASME PCC-1), gasket selection and assembly for obtaining desired performance/reliability (Example LDAR), and sharing of Lessons-Learned and Best Practices from industry experts and engineering colleagues.
