Overpressure Protection Design

Overpressure Protection Design

PCI Engineering provides engineering design and verification services for overpressure protection systems to ensure the safety and integrity of pressurized equipment and piping.

Our team applies the principles of ASME Section VIII, CSA B51, and other relevant standards to develop systems that prevent equipment failure and maintain regulatory compliance.

We design and evaluate relief valve systems, rupture discs, and control-based protection methods to ensure proper sizing, set pressures, and response characteristics for each application.

PCI also performs system reviews and audits to confirm that existing protection devices provide adequate coverage under all credible overpressure scenarios.

Our approach emphasizes safety, reliability, and practicality—ensuring that protection systems are not only compliant but optimized for real-world operation and maintainability.

By combining detailed engineering analysis with operational experience, PCI delivers effective, code-compliant overpressure protection solutions for both new and existing facilities.
