Expanded graphite gaskets for high temperature applications
Manufactured using advanced processing technology, the FlatSeal™ HMF30 Series is a family of expanded graphite gaskets designed to effectively seal under extreme temperatures and pressures and in applications containing harsh chemicals.
The FlatSeal™ HMF30 series of graphite based flat gaskets has been specially engineered for use in extreme operating environments. Each material consists of a high-performance graphite foil, which can be combined with a metal layer or layers and XP Technology, giving each material its own unique performance profile.
Features and benefits
Suitable for temperatures from -200 °C to +550 °C / -364 °F to +1022 °F
Retains sealing performance with changing loads
Maximum adaptability to flange unevenness
Extreme low creep in high temperature applications
Universal chemical compatibility
XP Technology maximizes oxidation resistance and minimizes downtime for maintenance
Meets TA Luft (Technical Instructions on Air Quality Control) fugitive emissions requirements
Suitable for designs that must comply with VDI (Verein Deutscher Ingenieure, German Association of Engineers) guideline 2290
FlatSeal™ HMF30 and HMF32 - Versatile graphite gaskets
Made from high quality expanded graphite, FlatSeal™ gaskets in HMF30 and HMF32 are excellent all-around gaskets for high temperature and pressure applications. They demonstrate wide-ranging media compatibility and can withstand alternating loads.
Reinforced with an expanded metal layer, FlatSeal™ HMF30 suitable for a wide range of uses, which optimizes logistics and handling processes.
FlatSeal™ HMF32 (blue printing) combines the characteristics of FlatSeal™ HMF30 with innovative XP Technology. This makes graphite more resistant to oxidation for extended sealing performance and significantly reduces graphite deposits on sealing surfaces, facilitating maintenance processes.
FlatSeal™ HMF31 and HMF33 - Optimized sealing performance to meet fugitive emissions requirements
Specially engineered to meet fugitive emissions requirements, FlatSeal™ gaskets in HMF31 and HMF 33 feature a special impregnation to minimize leakage at the flange in high temperature and pressure applications. These gaskets are suitable for use in applications that must comply with TA Luft and VDI guideline 2290.
FlatSeal™ HMF31 is an excellent all-round standard gasket, ideal for a broad range of processing applications.
Enhanced with XP Technology, FlatSeal™ HMF33 (blue printing) offers superior leakage performance with maximum oxidation resistance to extend gasket life and features anti-stick properties, simplifying gasket replacement processes.
FlatSeal™ HMF36 - Unique multilayer structure for superior performance
With its innovative multilayer concept, FlatSealTM HMF36 offers outstanding adaptability to flange surfaces and the highest mechanical stability. It is made from expanded graphite foil reinforced with a combination of expanded and smooth metal layers.
This high-performance flat gasket is suitable for use in operating environments with extremely high pressures and temperatures and can withstand changing loads. It meets TA Luft fugitive emissions requirements and can be used in designs that must comply with VDI guideline 2290.
FlatSealTM HMF36 is equipped with XP Technology, which extends service life and simplifies maintenance operations.
