To verify structural integrity and dimensional conformity, our quality assurance process covers the following verifications:

Material Verification: Spectrometer testing to verify chemical composition against material standard specifications.

Dimensional Inspection: 100% measurement verification to confirm adherence to ISO 8062 CT 6-8 tolerances.

Subsurface Evaluation (NDT): Non-Destructive Testing protocols, including Radiographic Testing (RT) or Ultrasonic Testing (UT) based on project specifications, to detect internal porosities, blowholes, or subsurface casting defects.

Balance Testing: Dynamic balance verification for centrifugal pump component flanges to manage operational vibration.
