NDT SERVICES

We provide NDT services like

  • Radiography Testing
  • Ultrasonic Testing
  • Magnetic Particle Testing
  • Penetrant Testing

Post-Weld Heat Treatment Services:

In addition to NDT and inspection services, GSM provides Post-Weld Heat Treatment for plant piping after welding has been carried out to relieve residual stress that develops during the welding process. This also increases the toughness of the weld which avoids service cracks.
