Rubber Steel Gaskets
Rubber steel gaskets
The good cost-efficiency (reduced stock keeping, re-useability) of the rubber steel gaskets R-ST (gummi stahl dichtung in German) is combined with excellent handling.The latter is shaped by the rigid steel ring core – even at large nominal widths – and the non-sensitivity against unwanted stresses during assembly. The vulcanisation achieves an extreme adhesion between the steel insert and the rubber sheathing. Shifting, separating or blowing out even at the highest stresses is impossible. The lens-shaped base body of the rubber steel gasket R-ST-O/IR profile gasket is combined with an O-ring as a static sealing element which disposes the need for a costly grooving of the flange.
The advantages of rubber steel gaskets G-ST gaskets are:
- Tight at even low bolt tightening torques
- Compensates surface faults
- Flange and screws can be weaker in their design
- Angle deviations can be compensated more easily than for flat gaskets
- Sheathing materials: NBR, EPDM, CSM, FPM and other materials upon request
Features of the rubber steel gaskets or gummi stahl dichtung
- High tightness with low bolt loads
- Adaptable sealing surface – optimum balances of flange unevennesses
- Safe against shifting or squeezing of the gasket by the steel insert
Areas of Application/ Appliances of the rubber steel gaskets
- Pipeline construction, gas and water supply
- Rubberised flanges, plastic and GRP flanged joints
- Pipelines in vacuum operation
- Enamelled pipeline and apparatus flange surfaces
