Improper torque of high-pressure vessels poses significant safety risks, leading to financial losses, property damage, and even loss of life. This white paper underscores the critical importance of ensuring flanges and bolts are properly torqued and audited, particularly when dealing with volatile substances. Compliance with regulations such as the Clean Air Act's Leak Detection and Repair program is essential for controlling fugitive emissions. Studies highlight the prevalence of flange joint failures due to loose bolts, emphasizing the need for stringent torque management practices. By prioritizing joint integrity and effective torque management, plant operators can enhance operational efficiency, reduce costs, and mitigate risks associated with pressure-containing joints.
Proper torque management is critical for ensuring the integrity of high-pressure vessels and preventing safety incidents. Volatile substances amplify the risks associated with improper torque, underscoring the need for stringent precautions. Compliance with regulatory mandates, such as leak detection and repair programs, is essential for mitigating fugitive emissions and maintaining environmental stewardship. Operators can enhance safety, minimize financial losses, and protect personnel and the environment by prioritizing proper torque techniques and audits.
Real-world incidents, such as the leakage and fire in Arita, Wakayama, Japan, underscore the catastrophic consequences of uneven tightening torque and "creep" phenomena. Additionally, insights from organizations like the International Occupational Safety and Health Information Centre highlight the prevalence of leakage incidents and the importance of comprehensive inspection and assessment protocols. By learning from these experiences and leveraging industry best practices, operators can enhance their torque management strategies and bolster operational resilience.
