Components Summary Table

Critical Welding & Assembly Specifications

Material Handling & Non-Destructive Examination (NDE)

• Material Integrity: All wetted parts and welding consumables must be compatible with SS316L (022Cr17Ni12Mo2).

• Sequence of Inspection: 1. Perform 100% Liquid Penetrant Testing (PT) after the initial strength weld. 2. Repeat 100% PT after hydraulic expansion to verify that no micro-cracking occurred during the expansion process.

• Final Non-Destructive Examination: All pressure-retaining welds require 100% Liquid Penetrant Testing (PT).

Post-Weld Treatment

• Chemical Cleaning: The entire unit must undergo complete Pickling & Passivation after final fabrication is complete.

• Surface Roughness: All wetted surfaces must maintain a finish of Ra3.2.

• Zero Dead Leg: Vent and drain nozzles must be configured with blind flanges to ensure a "Zero Dead Leg" design.

Testing, Inspection & Preservation

• NDE: 100% Liquid Penetrant Testing (PT) for all pressure-retaining welds.

• Leak Testing: Pneumatic bubble leak test at 1.7 bar held for 30 minutes.

• Chemical Treatment: Full pickling and passivation of the entire unit.

• Preservation: Internal cavities dried to a -40C dew point and pressurized with a 0.5 bar nitrogen blanket.​
