FDC Composite Dome Type Bursting Discs – Rupture Discs

FDC – Composite Dome Type Bursting Discs – Rupture Discs

These rupture discs are designed and manufactured by FDC, who have over 25 years of experience in this highly competitive international market. Their products can be specified to product standards including KS B ISO 4126, KOSHA, ASME Code Section VIII, API RP520, and the ISO-9001:2008 quality system.

Composite domed bursting discs rely on the combination of the top domed section that is laser cut and the seal to prevent leakage. A vacuum support is also used for vacuum resistance to full vacuum or in some cases – large back pressure. The composit e domed burting disc is a forward acting tension loaded disc that can be reliably operated in static and mild pressure cycling conditions from full vacuum to 80% of its burst pressure.

KSRC

For both liquid and steam media environments, KSRC composite dome bursting disc is perfect for a wide range of applications.  KSRC composite dome type bursting disc excels in conditions involving counterpressure, vacuum, and pulsation.  Vacuum Support option is also available with this composite dome type bursting disc.

This KSRC disc delivers precise rupture performance and unparalleled reliability. With its suitability to withstand medium to high pressure, KSRC burst disc guarantees corrosion resistance based on the Seal disc materials used. For example, if the Seal disc material is chosen as Teflon, it may be vulnerable to high temperatures.

Please bear in mind that the temperature range is generally limited by the seal disc material.

Design:
· Composite Dome Sloped Seat Type
· It is used with installation on FDC standard holder
· Composite/Dome structure ruptured by slit processed on Top disc
· It consists of Top disc, Seal disc and Vacuum disc

KSRRCH

KSRRCH composite dome bursting disc is versatile and can be used in various environments as well, including those involving liquid or steam media. It’s worth noting that if the Seal disc material is Teflon, it may be susceptible to high temperatures. However, it performs exceptionally well under counterpressure, vacuum, and pulsation conditions. Additionally, we offer vacuum support to meet your application needs.

This KSRRCH composite dome bursting disc is suitable for mid to low-pressure applications, and its resistance to corrosion is determined by the Seal disc materials. Please keep in mind that the temperature range is generally limited by the chosen seal disc material explained as above. KSRRCH composite dome bursting disc delivers precise rupture performance and boasts excellent reliability.

Design:
· Composite Dome Flat Seat Type
· It is used with installation on FDC standard holder
· Composite/Dome structure ruptured by slit processed on Top disc
· It consists of Top disc, Seal disc and Vacuum disc

Also available:
