Material inspection
Incoming SS304 pipe and fittings are checked for dimensions, wall thickness and material identity before fabrication.
- Dimensional checks
- Wall-thickness verification
- Material traceability
Manufacturing quality control
ITP-driven fabrication quality.
MIT Water links material verification, qualified welding, fabrication checks and non-destructive examination through documented ITP hold and verification points.
ASME Section IX WPQ
Pipe welding is performed by personnel qualified in accordance with ASME Section IX, an uncommon capability in China's water-treatment fabrication field.
- Welder performance qualification
- Qualified welding process
- Controlled stainless-steel fabrication
RT & PT examination
Radiographic testing and penetrant testing are incorporated where required by the ITP and project specification.
- RT film examination
- PT surface examination
- Documented acceptance records
304 stainless-steel pipe welding
ASME Section IX
Qualified welding is part of MIT Water's ITP.
Qualified welding supports stainless-steel pipework and skid fabrication quality for BWRO, SWRO and other high-pressure RO systems.
Pickling & passivation
Surface treatment after stainless-steel fabrication
After welding and fabrication, stainless-steel pipework can be pickled and passivated to improve surface condition and support corrosion resistance.
