Detalle del producto
A zirconium blind flange is a non-bored flange designed to seal the end of a piping line, vessel opening or equipment nozzle where future inspection, maintenance or system expansion may be required. Because zirconium offers outstanding resistance to many organic acids, alkalis and chloride-bearing media, these blind flanges are widely selected for chemical processing, acetic acid production, plantas farmaceuticas, offshore systems and specialty corrosive services.
SASA FLANGE supplies forged and machined zirconium blind flanges in standard and custom dimensions with strict process control. Available documentation and inspection include chemical analysis, pruebas mecanicas, inspección dimensional, Pruebas del PMI, EN 10204 3.1 Certificado y trazabilidad completa del número de calor.. Perforación personalizada, special facing and non-standard thicknesses can be produced to suit project drawings and service requirements.

Inspección del producto
1. Inspección de composición química
Chemical composition inspection is performed to verify the zirconium grade conforms to ASTM requirements for UNS R60702 or R60705. Spectrometric analysis and review of mill data confirm control of Fe, cr, hf, oxígeno, nitrogen and hydrogen limits. This ensures the flange material has the required corrosion resistance and suitability for aggressive chemical process environments.
2. Pruebas de propiedades mecánicas
Mechanical testing confirms the flange forging meets specified tensile strength, límite elástico, requisitos de elongación y dureza. Test coupons are evaluated according to the applicable material standard and heat treatment condition. These checks help ensure the blind flange has adequate strength for bolted closure service while retaining the ductility needed for safe installation and operation.
3. Inspección dimensional
La inspección dimensional cubre el diámetro exterior., espesor, círculo de pernos, diámetro del agujero del perno, facing dimensions, raised face height and overall flatness. The sealing surface finish is checked to match the gasket requirement of RF, FF or RTJ design. This inspection is essential for proper alignment, leak-tight assembly and interchangeability with mating flanges made to international standards.
4. Pruebas PMI y pruebas hidrostáticas
PMI testing is carried out to confirm positive identification of zirconium alloy grade and to avoid mixed-material risk during production and packing. Cuando se especifica, hydrostatic or assembly pressure verification is performed at system level or as project requirement. SASA FLANGE proporciona EN 10204 3.1 certificado, inspection reports and heat number traceability for complete documentation.
