Confidently Achieve Safe & Reliable Operations

Properly designed, installed, and maintained pressure relieving devices (PRDs) are a critical part of all mechanical integrity programs. At E2G, our multi-disciplinary team will document the relief system design basis, retrofit PRD installations, and develop inspection plans for testing and overhaul of relief devices.

PRD Mechanical Integrity Services

  • Determine if relief device integrity program meets latest guidelines and generally accepted good engineering practice (OSHA 1910.119)
  • Review facility’s PRD standards for compliance with local jurisdictional requirements and ASME and API guidelines
  • Perform or review calculations, including PRD sizing and installation assessment (inlet/outlet pipe sizing and routing)
  • Assess existing surge analysis for pipelines or perform new analysis
  • Develop platform to collect, store, and maintain project data, including a comprehensive record of existing PRDs
  • Determine inspection intervals using a relief risk-based inspection (RBI) assessment
  • Provide project management services to deliver a complete package of supporting documentation and an RBI inspection plan
E2G uses risk-based inspection (RBI) to quantify risk and make informed decisions about how, when, and where to inspect PRDs. This optimized approach to PRD inspection can significantly reduce maintenance costs without jeopardizing the safety of the plant.
