| Bell and spigot joint with double O-ring gasket (B&S) |
 |
 |
|
|
|
|
| Joint classification: |
| Mechanical, slightly flexible. |
|
| Material: |
|
(GRP/GRVE): “E” glass rovings, mats and woven rovings impregnated with resin (to be selected in relation to the conveyed fluid and to the design temperature).
|
|
| Description: |
Bell and spigot ends are built during the pipe manufacturing to obtain a monolithic structure. Hydraulic tightness is guaranteed by n°2 elastomeric O-ring gaskets placed into the spigot grooves.
The test nipple (eventually available from diameter DN200) allows to pressurize the O-rings chamber to check the coupling hydraulic tightness immediately after the joint assembly.
|
|
| Applications: |
Used in piping systems for marine, civil and industrial applications with aboveground and underground installations.
|
|
| Benefits: |
- Quick assembly;
- Checking of the joint hydraulic tightness immediately after the assembly with the test nipple;
- Ideal to substitute the traditional mechanical couplings (Helden, Teekay, Straub, Reka, etc..) in order to obtain an homogeneous pipeline concerning materials and corrosion resistance;
- Small misalignments absorption during installation (magnitude related to the diameter);
- Thermal expansion absorption;
- Reduction of possible vibrations thanks to the O-ring gaskets;
- Joint monolithically manufactured onto the pipe.
