Inspection & NDT (Non-Destructive Testing)

• Radiographic Examination (RT): * 100% RT for all pressure butt-welds

• Ultrasonic Examination (UT): All pressure-retaining butt welds and nozzle attachments shall be fully examined per ASME Sec. VIII, Div. 1 (UW53 & Appendix 12).

• Magnetic Particle Examination (MT): * Required for all welded joints of low alloy steel and lifting lugs per App. 6 of ASME Sec. VIII Div. 1​

Hydro​static Test

• Medium: Clean potable water

• Duration: Maintain test pressure for at least one hour per 25mm of total nominal shell thickness.

• Sequence: No painting is permitted before the hydrotest, leak test, and weld inspections are approved.

• Post-Test: Equipment must be cleaned thoroughly to remove scales and foreign materials.
