Quality

  • Raw material verification via laboratories / test certificates
  • Stage-wise inspection protocol
  • Dimensional checks for overall finish / correctness
  • General checks for geometric defects
  • Post-weld heat treatment
  • Mock-assemblies undertaken, wherever possible
  • NDT / DP Tests for detection of surface discontinuities
  • RT Test for internal flaws
  • Check on weld fit-ups / root welds / embrittlements
  • Weld / process defect checks
  • WPS as per ASME Section IX
  • PQR Acceptance as per ASME Section IX
  • Surface treatment of finished material
  • Pickling and passivation
  • Sand-blasting, clearing and primer application
  • Painting, with check on coating thickness
