Active Quality Management
Non Destructive Examination (NDE) in our own AZ labs
- PMI (Positive Material-Identification)
- Ferrite testing acc. to ISO 17655
- Dye penetrant test acc. to ISO 3452 and ASME B 16.34
- X-ray tests acc. to EN 12681 / ASTM E446 / ASME B 16.34
- Strength and tightness tests acc. to EN 12266, API 598, ISO 5208, MSS-SP-61
- High pressure tightness test with water & gas up to PN 160 / CL 900
- vacuum test
- Helium emission test acc. to TA-Luft, ISO 15848-1 / -2 and API 641

Production controls
- Performance tests
- Dimensional checks
- High-voltage test of linings (20 kV) acc. to ISO 2746
- Wall thickness test
- Oil and grease free test using UV light
- Surface & paint tes, such as layer thickness, surface roughness, ferroxyl test, salt test, passivation layer, water drainage
- In-house FROSIO inspection
Quality standards in the manufacturing process
- certified welders/welding procedure approvals (MIG, MAG and WIG)
- 3D-CAD computer-aided design with CFD computational dynamics, e.g. for control valves
- CNC manufacturing for maximum accuracy
- full traceability
- approved suppliers

Additional inspections
- all other non-destructive or destructive tests by external labs
