ASME Section VIII Div 1 & 2 · NBIC NB-23

API 510 Pressure Vessel Inspection

Authoritative visual and non-destructive examination across towers, fractionators, hydrocracker drums, reactors, and shell-and-tube exchangers. Our inspectors establish baseline profiles, calculate remaining corrosion allowances, and specify repair scopes.

  • Internal Tray & Demister Inspections: Comprehensive internal entry assessing bubble cap trays, structured packing, distributors, and support rings.
  • Corrosion Rate Modeling: Precise UT thickness profiling and localized thin area (LTA) calculations according to API 510 & API 579.
  • R-Stamp Alteration Oversight: Direct review of contractor welding procedures, weld map tracking, and post-weld heat treatment (PWHT) compliance.
  • De-isolation Sign-Off: Pre-commissioning internal cleanness verification, nozzle clear-out, and final manway closure sign-offs.

QA/QC Site Supervision & Turnaround Lead

Owner-oriented field quality leadership. We eliminate costly rework by auditing mechanical contractors in real time, validating welding procedures (WPS/PQR), and enforcing defect clearance before hydrotests and unit startups.

  • Contractor Audit & Surveillance: Verification of welder qualifications (WPQ), rod oven temperatures, preheat logs, and fit-up tolerances.
  • Hydrotest Boundary Packages: Inspection of test limits, blind registers, calibrated gauge certification, and controlled de-pressurization.
  • Flange Mapping Programs: 100% torque sign-off logs, lubricant compliance, and optical gasket face verification.
  • 24/7 Shift Handover Management: Seamless day/night shift turnaround turnover packages with zero missing punchlist items.
