Bonded Seals
Bonded Seals (ook wel bekend als Dowty Seals of Usit ringen) zijn statische afdichtingen voor het afdichten van flensverbindingen van boutkoppen, hydraulische leidingen, schroefkoppelingen en sluit en dop moeren.
Door het gebruiken van Bonded Seals voorkom je lekkage van gassen of vloeistoffen in uw toepassing.
Bonded Seals word over het algemeen veel gebruikt in hydraulische systemen. hier worden ze vaak toegepast in een toepassing waar je een boutkop moet afdichten.
Bonded seals zijn, vanwege de metalen buitenring, zeer geschikt voor hoge druk systemen.
Materialen
Een Bonded Seal heeft een metalen buitenring met aan de binnenzijde gevulkaniseerde trapeziumvormige afdichtingsring.
Welk materiaal er gebruikt moet worden hangt af van uw toepassing. Met welk medium en temperatuur komt het in aanraking?
Daarbij moet er ook rekening gehouden worden met de druk en tijd. Bij een Bonded Seal bepaalt de metalen ring altijd de maximale druk die het product aankan.
Het meest voorkomende materiaal bij Bonded Seals is RVS en Staal, met als elasomeren NBR en Viton (FPM, FKM).
Materialen metaal:
Staal verzinkt CR6 vrij, RVS 304 en RVS 316 Stainless Steel, zink verchroomd
Materialen elastomeren:
NBR, Viton (FPM, FKM), Epdm, Silicone (VMQ) , FVMQ, HNBR, EPDM, CR.
Tevens met toelatingen als KTW, WRC, NSF, WRAS, ACN en FDA, R67 01 LPG GAS.
Uitvoeringen
Een Bonded Seal is leverbaar in meerdere uitvoeringen:
De bekendste zijn de zonder centrering en met centrering.
Een Bonded Seal met centrering heeft zijn voordelen. Met centrering blijft de bonded seal / usitring Multi Seal gefixeerd op de bout of koppeling zitten.
Ideaal dus op moment van montage en demontage.
Afmetingen
De maat/afmeting van een Bonded Seal is afhankelijk van de afmetingen van de moer, schroef, Bout of flens die u wilt afdichten.
De normering van de Bonded Seal is dan gelijk aan de normering van de bout, moer, schroef of flens.
U kunt de Bonded Seal ook selecteren op metrische maten.
Afmetingen Inch / BSP
Onder andere: 5/8 – 11/16 – 1/8 – 1/4 – 3/8 – 1/2 – 5/8 – 5/ 16 – 7/16 – 9/16 – 11/16 – 15/16 – 3/4 – 7/8 – 1 – 1 1/16 – 1 3/16 – 1 5/16 – 1 1/4 – 1 1/8 – 1 1/2 – 1 3/8 – 1 5/8 – 1 7/8 – 1 3/4 – 2 – 2 1/8 – 2 1/4 – 2 1/2
Afmetingen M Metrich
Onder andere: M3 – M4 – M5 – M6 -M8 – M10 – M11- M12 – M13 – M14 – M15 – M16 – M17 – M18 – M20 – M21 – M22 – M24 – M26 – M27 – M28 – M30 – M33 – M36 – M40
