Stenflex rubber expansion joint type RS-2 or type RS-4
Product information
Stenflex rubber expansion joint type RS-2 and type RS-4 are flameproof rubber expansion joints with steel cord inlays, rotatable flanges and tension rods. Various flange drillings are possible in this set-up. These types are comparable to the AS-2 expansion joint, but with an overall length of 130 mm. Thanks to the tension rods, the pressure reaction force is absorbed in a system.
Type RS-2 and type RS-4:
- With type RS-2, the tension rods are only limited on the outside, so that the expansion joint cannot extend.
- With type RS-4, the tension rods are limited on the outside as well as on the inside, so that the expansion joint cannot extend and cannot be pressed in. As in the case of a vacuum.
Specifications
- Rubber grade: EPDM and NBR rubber
- Range: DN 25 to DN 300
- Temperature: max. 130°C
- Pressure rating: PN 16
Application
Types RS-2 and RS-4 are in fact R expansion joints with steel cord inlays. These inlays ensure that the RS expansion joint can be used in applications up to 130°C and that it meets the flameproof requirements. Thanks to the flameproof properties, these expansion joints can also be used in fire risers.
Flameproof is a requirement in ship engine rooms. The RS expansion joints have passed flameproof tests at several classification societies and therefore carry many type approvals for use on ships. The RS expansion joints are also suitable for use in central heating systems and are TÜV/DIN 4809-approved.
