Stenflex rubber expansion joint type B-2 or type B-4
Stenflex rubber expansion joint type B-2 and type B-4 are high-wave rubber expansion joints with rotatable flanges and tension rods. Various flange drillings are possible in this set-up. They are designed to absorb large movements.
Thanks to the tension rods, the pressure reaction force is absorbed in a system. The tension rods are integrated up to DN 150. From DN 175, the set-up features a short overall length, threaded holes and loose segment restraint.
Type B-2 and type B-4 :
- With type B-2, the tension rods are only limited on the outside, so that the expansion joint cannot extend.
- With type B-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.
- Rubber grade: EPDM and NBR rubber
- Range: DN 32 to DN 400
- Temperature: max. 100°C
- Pressure rating: PN 16
Stenflex rubber expansion joints type B-2 or type B-4 are used to compensate large lateral displacements or when a short overall length is required.
