SMLSCO Class 600 flanges undergo rigorous quality control to ensure safe high-pressure performance:
- 100% PMI material verification for F316 grade accuracy
- Precise dimensional measurements per ASME B16.5 standards
- Penetrant testing (PT) on sealing surfaces to eliminate leakage risks
- Comprehensive inspection of critical working surfaces
Solid flanges without center holes designed for pipeline end sealing and reserved openings. Unlike permanent pipe caps, blind flanges offer detachable connections for future maintenance, extension, or system modifications.
- Pipeline end closure and pressure vessel isolation
- Detachable design for maintenance flexibility
- Pressure capacity matching pipeline system requirements
- Absolute safety and sealing reliability
Raised Face (RF) sealing surfaces concentrate bolt pre-tightening force on smaller areas, generating higher compressive stress for reliable sealing. SMLSCO provides various sealing surfaces including:
- Raised Face (RF) - Most widely used for standard applications
- Full Face (FF) - Suitable for low-pressure conditions
- Ring Type Joint (RTJ) - Designed for ultra-high pressure requirements
The global standard defines six pressure-temperature rating levels: Class 150, 300, 600, 900, 1500, and 2500. Class 600 represents medium to high pressure capacity, specifically engineered for demanding conditions in petroleum, chemical, and power generation industries.
SMLSCO maintains over 500 tons of stainless steel forged flange blanks, enabling rapid machining for custom requirements including F316 materials, Class 600 pressure ratings, and special sizes. This strategic inventory approach delivers significantly faster production cycles compared to traditional manufacturing methods.
