Rubber pipe expansion joint PN 6 - 16

roundflangefor gas

The bellows of rubber expansion joints consist of an inner and outer elastomer layer and several intermediate layers made of Nylon-cord tissues. The Nylon-cord or Aramid layers ensure high resistance against internal pressure and vacuum. The rubber expansion joints with bellows type A, B, D and S are fitted with loose flanges; the bellows type A, B and D can also be equipped with screwed sockets. The steelwire reinforced rims of the bellows with loose flange design have a sealing effect. The rubber expansion joints with bellows type C have fully modeled rubber flanges with loose back flanges. Rubber expansion joints can be run through by various media, if the maximum permissible operating conditions are respected. Details may be taken from the according tables.
