NDT for Pressure-Retaining Equipment
Our ASNT/PCN certified NDT technicians inspect welds, base materials, and structural components using a full range of methods. We serve oil refineries, gas processing plants, petrochemical facilities, and power stations.
NDT Methods
- Visual Testing (VT) — baseline inspection
- Liquid Penetrant Testing (PT/FPI) — surface cracks
- Magnetic Particle Testing (MT) — ferromagnetic surface and near-surface flaws
- Ultrasonic Testing (UT) — thickness measurement and internal defects
- Phased Array Ultrasonic Testing (PAUT) — complex geometry welds
- Radiographic Testing (RT) — volumetric inspection of welds
- Hardness Testing — Brinell, Rockwell, Vickers
- Positive Material Identification (PMI)
Applications
- Pressure vessel inspection
- Pipeline weld inspection
- Storage tank floor and shell inspection
- In-service inspection of heat exchangers and boilers
- Pre- and post-weld inspection
- Fitness-for-service assessment
