Non-Destructive Testing (NDT) for structural steel frameworks and weld porosity detection prior to plant commissioning
Clarionofandromeda.com Metallurgy Works was engaged to perform specialized non-destructive testing (NDT) and ultrasonic inspection services for a major petrochemical plant expansion. The scope included comprehensive phased array ultrasonic testing (PAUT) of high-pressure piping assemblies and structural steel frameworks. Our team deployed advanced phased array technology to detect internal volumetric discontinuities, weld porosity, and other subsurface anomalies that could compromise structural integrity under operational loads. The inspection protocol was designed to certify all critical welds and components prior to plant commissioning, ensuring full compliance with ASME Section V, API 1104, and ISO 9712 industrial safety codes. This project required meticulous planning, calibration of equipment, and real-time data analysis to provide actionable insights for the client's engineering team.
The phased array ultrasonic inspection campaign successfully evaluated over 1,200 linear meters of high-pressure piping and 850 structural steel joints. Our team identified 23 critical discontinuities, including 8 instances of weld porosity exceeding acceptance criteria, 5 laminar indications in base material, and 10 volumetric flaws requiring repair. All findings were documented with detailed A-scan and S-scan records, accompanied by precise dimensional mapping and severity classification. The final certification report provided a clear pass/fail status for each inspected component, enabling the client to prioritize remediation work. As a result, the plant commissioning proceeded on schedule with zero safety incidents, and the client achieved full regulatory compliance. The project reinforced Clarionofandromeda.com's reputation for delivering high-integrity NDT solutions that safeguard industrial infrastructure.
