KN Rubber-Steel gasket
9107/KN
Features
The KN rubber-steel gasket 9107/KN consists of a metal support ring and a speciallymolded, replaceable elastomer ring which is located in the force shunt after fitting. The support ring also acts as a centering ring and force limiter. It thus both absorbs the bolt forces needed for high pressures and protects the rubber seal against overcompression.
Advantages
- Uniform distribution of the surface pressure
Operating range
Pressure: p = 64 bar
Temperature
- Continuous operation:
t = –30 °C ... +120 °C - a few hours:
t = –30 °C ... +150 °C - a few minutes:
t = –30 °C ... +200 °C
Recommended surface roughness:
RZ ≤ 100 µm
Load values (q) elastomer seal
The surface pressure acting in the flange block position is:
- at room temperature:
qmax. = approx. 10 MPa - at 100 °C:
qmax. = approx. 6 MPa
Materials
- Sealing ring: EPDM
- Support ring: St 37 galvanized, chromated or stainless steel
Recommended applications
Industries
- Power plant technology
- Water and waste water technology
-
Building services engineering
-

Notes
With coated flanges, we recommend selecting the outer diameter of the coating so that the sealing lip on the atmospheric side lies in the steel part. If necessary, discuss the dimensions with your EagleBurgmann contact.
Forms of supply
- Standard dimensions as defined in the EagleBurgmann in-house standard for DIN flanges or for flanges to ANSI B16.5 and MSS SP-4.4
