Truco’s flanged bellows are made from:

  • EPDM
  • Neoprene
  • Butyl
  • Nitrile
  • Hypalon

Tie-rods available for high-movement pipelines

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.
