Which media and temperatures allow using the Flat gasket for 4â TTMA flange, type FF made of EPDM, SPETOGRAF GUS31, PTFE, or Viton at the stated working pressures?

Flat gasket for 4â TTMA flange, type FF Format . media and temperatures for use: - EPDM (working pressure up to 60 bar): suitable for water, steam (low pressure), many alkalis and acids, and weather/ozone-exposed applications. Temperature range: â30Â°C to +120Â°C. Not recommended for oils, fuels or hydrocarbons. - SPETOGRAF GUS31 (working pressure up to 100 bar): broad chemical resistance including aggressive chemicals and hydrocarbons; suitable for cryogenic to very high temperatures. Temperature range: â200Â°C to +650Â°C. Selection for specific media and pressures must be agreed with TUBES INTERNATIONALÂ®. - PTFE (working pressure up to 300 bar): excellent chemical resistance (strong acids, bases, solvents), suitable for oils, fuels and many aggressive media. Temperature range: â200Â°C to +220Â°C. - Viton (working pressure: use per selection with TUBES INTERNATIONALÂ® . material listed without explicit max in source): good for oils, fuels, hydrocarbons, many chemicals; Temperature range: â20Â°C to +200Â°C. For pressure limits and compatibility at given temperatures, confirm with TUBES INTERNATIONALÂ®. Note: Permissible working pressure depends on both temperature and the specific medium; final selection and allowable pressures must be agreed with TUBES INTERNATIONALÂ®.

Can the Flat gasket for 4â TTMA flange, type FF be used with steam or aggressive chemicals at the specified pressures and temperatures?

Flat gasket for 4â TTMA flange, type FF: suitability for steam or aggressive chemicals depends on gasket material, temperature and pressure; final selection must be agreed with TUBES INTERNATIONALÂ®. Summary of capabilities: - EPDM: working pressure up to 60 bar, temperature -30Â°C to +120Â°C - suitable for steam only in limited lowâtemperature/pressure cases; not recommended for aggressive chemicals. - SPETOGRAF GUS31: up to 100 bar, -200Â°C to +650Â°C - suitable for steam and many aggressive media at high temperatures/pressures, subject to compatibility check. - PTFE: up to 300 bar, -200Â°C to +220Â°C - excellent chemical resistance including aggressive chemicals and usable with steam within temperature/pressure limits. - Viton: -20Â°C to +200Â°C (working pressure must be verified caseâbyâcase) - good chemical resistance and usable with steam at compatible pressures/temperatures. Always confirm medium compatibility and permissible working pressure at the specific temperature with TUBES INTERNATIONALÂ® before use.

Is Flat gasket for 4â TTMA flange, type FF suitable for cryogenic applications and which materials apply?

Flat gasket for 4â TTMA flange, type FF can be suitable for cryogenic applications depending on the selected material. From the provided material data: - SPETOGRAF GUS31: Operating temperature range from â200Â°C to +650Â°C. suitable for cryogenic service. Working pressure up to 100 bar (final selection should be agreed with TUBES INTERNATIONALÂ® considering the medium and exact conditions). - PTFE: Operating temperature range from â200Â°C to +220Â°C. suitable for cryogenic service. Working pressure up to 300 bar (confirm suitability with TUBES INTERNATIONALÂ® for the specific medium and temperature). - EPDM: Operating temperature from â30Â°C to +120Â°C. not suitable for cryogenic temperatures below â30Â°C. - viton: Operating temperature from â20Â°C to +200Â°C. not suitable for cryogenic temperatures below â20Â°C. Conclusion: For cryogenic applications (temperatures down to â200Â°C), choose SPETOGRAF GUS31 or PTFE and verify permissible working pressure and medium compatibility with TUBES INTERNATIONALÂ® before final selection.
