Truco provides tie-rods to control the compression and the extension of the rubber flanged bellow in a pipeline.
Tie-rods are threaded and fitted with two triangular gusset plates that are drilled to match the Pitch Circle Diameter (PCD) of the bellows' flanges.
Tie-rods are used in applications where there is vigorous pipe movement present and stability is required.
Truco's flanged bellows are made from:
|
EPDM |
|
Neoprene |
|
Butyl |
|
Nitrile |
|
Hypalon |
