Quality Assurance & Testing
- Direct-reading Spectrograph analysis
- Hydrostatic testing machine validation
- X-ray detector inspection
- Ultrasonic flaw detector examination
- Magnetic particle detector verification
Certification Documentation: Raw Materials Certificate, 100% Radiography Test Report, Third Party Inspection Report
Key Advantages
- Cost-Effective Solution: Use expensive corrosion-resistant alloys only for stub ends while employing carbon steel for backing flanges
- Easy Alignment: Rotatable flange design simplifies bolt hole alignment during assembly
- Maintenance-Friendly: Ideal for systems requiring frequent dismantling for inspection or routine maintenance
Technical Considerations
- Crevice Corrosion Risk: Potential contaminant collection between flange bore and stub end surfaces
- Stress Limitations: Recommended for applications with minimal longitudinal stresses from pressure, weight, and thermal expansion
- Galvanic Corrosion: Possible when using dissimilar materials for flange and stub end components
