Can the IBC Flat Gasket for PN Flange, SPETOGRAF GUS31, be used across different PN classes and what temperature and pressure limits apply?

Yes. The IBC Flat Gasket for PN Flange, SPETOGRAF GUS31 can be used across different PN classes provided the gasket outer diameter matches the flange class. Example: a DN10 PN40-sized gasket is compatible with PN10, PN16 and PN25 flanges. Temperature and pressure limits: SPETOGRAF GUS31 resists from −200 °C to +650 °C and can withstand working pressures up to 100 bar. Always select the gasket based on medium and operating temperature and confirm final choice with TUBES INTERNATIONAL® to ensure safety and correct sizing.

Is the IBC Flat Gasket for PN Flange, SPETOGRAF GUS31, suitable for aggressive chemical media and what are its chemical resistance limits?

Yes — the IBC Flat Gasket for PN Flange, SPETOGRAF GUS31 is suitable for many aggressive chemical media thanks to the SPETOGRAF GUS31 material, which provides exceptional thermal and mechanical stability (service range −200°C to +650°C and up to 100 bar). However, chemical compatibility is limited by the specific aggressive agent, its concentration and temperature. General limits and guidance: - Highly resistant: many acids, alkalis and solvents at moderate concentrations and temperatures due to the engineered SPETOGRAF composition and high thermal stability. - Conditional use: strong oxidisers, halogenated hydrocarbons, and some aggressive organics may attack the gasket at elevated temperatures or concentrations — compatibility must be checked case-by-case. - Not recommended without verification: certain aggressive oxidising acids, molten alkalis at high temperature, and specialty corrosives where polymer/graphite-based materials are known to degrade. Final selection requirement: always confirm compatibility with the exact medium, concentration and operating temperature/pressure. TUBES INTERNATIONAL® consultation is recommended to validate suitability and ensure safe, long-term performance.
