Bell & Spigot Joint
N. Sguassero manufactures a range of joints that can be installed easily without the aid of specialized personnel and without using any kind of "glue/adhesive" component.Among these joints there is the “BELL & SPIGOT ” joint, used in industry, in civil works, on board of ships and on every pipeline where it is required to:
- absorb thermal expansions;
- absorb misalignments;
- absorb eventual pipeline movements;
- absorb eventual vibration thanks to the O-Ring gaskets;
- allow eventual adjustments (within the limits of the indicated "gaps");
- substitute the traditional mechanical couplings (Helden, Straub, Reka or similar) in order to obtain an homogeneous pipeline in respect of materials and corrosion resistance.
As shown by the joint section, the seal is guaranteed by two "O-Ring"
gaskets of suitable materials for the conveyed medium, compressed into position.
These "O-Ring" are manufactured to the correct Shore hardness
values and to specific dimensions and normally included in the supply.
The "BELL & SPIGOT" joint may also be supplied with a locking device consisting of a Nylon 66 round or square rod, to be inserted through a hole in the Bell and into a groove on the Spigot after the two pipes have been pushed together, thus making a tensile resistant joint.
For particular applications, specific Customer's request or special requirements, the “BELL& SPIGOT DOUBLE O-RING" joint may be supplied with locking devices that simultaneously guarantee the possibility to absorb thermal expansions.
