Special expansion joints
- Nuclear
- Long length
- BPO
- BC1
- U joint
The special expansion joint series is available in three different sections and in unlimited lengths. The connection interfaces depend on the joint type and ensure optimal sealing.
Table of Dimensions and Mechanical Performance
Used primarily in nuclear power plants around the world, special expansion joints can be suitable for other applications (agricultural, condenser, turbine connection).
DILATOFLEX® - Long-length joints
Our special products are installed in nuclear power plants and provide a seal between the turbine and the condenser.
Lifespan: 15-20 years depending on usage conditions.
Different qualities of rubber: abrasion, temperature, different fluids (seawater, etc.)
Length from 16 m to 42 m (infinite possibility)
On-site or factory splicing
| Joint type | Application | Length | Construction | Assembly | Splicing | Specifics |
|---|---|---|---|---|---|---|
| BPO / OS | Turbine/condenser joint for thermal and nuclear power plants | 16 m to 42 m (infinite possibility) | Two cords and a textile braid derived from tyre technology | Jaw system | On-site or in the factory | Made to the desired length |
| BC1 | Turbine/condenser joint for nuclear power plants | 24.25 m | Two cords and a textile braid derived from tyre technology | Jaw system | On-site or in the factory | Fixed length of 24.25 m |
| U | Thermal and nuclear power plants | To the desired length | Rubber and polyester fabric | Bolting (custom drilling) | On-site or in the factory | Possibility of making right angles |
Additional information:
- Anvis Decize S.A.S. is certified "nuclear" and equips power plants around the world.
- We can manufacture joints of any length for your other applications.
- Different grades of rubber are available depending on the needs: abrasion resistance, temperature, different fluids (seawater...).
- The joints can be spliced on site or in our workshops depending on the project constraints.
