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
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
