Expansion Joints / Bellows


a) Fabric Expansion joints

  • Series of standard types of Fabric Expansion Joints along with numerous special designs.
  • Custom made Fabric Expansion Joints are also available in all sizes and shapes for any application.
  • Available from single bellows for ventilating systems to highly advanced multilayer expansion joints for gas turbine exhaust.
  • There are 26 standard types divided into five categories.
  • The temperature capability ranges from – 50?C to 1000?C and the pressure ranges from – 50 kPa to 50 kPa.

b) Elastomere Expansion joints

  • Suitable for continuous temperatures up to 200?C.
  • The Elastomere Expansion Joints are available in numerous shapes and sizes, but four elastomer products represent the standard range of LBH
    • PTFE polytetrafluoroethylene
    • EPDM ethylene propylene diene terpolymer
    • FKM fluorocarbon elastomer (Viton B)
    • SI silicone rubber

c) Metal Expansion joints

  • This covers any application where Fabric and Elastomere Expansion Joints are not suitable, mainly due to pressure conditions
  • Designed according to either EN14917, EN13445 or EJMA.
  • Standard designs are Axial-, Lateral-, Angular- and Universal Expansion Joints, in materials of stainless steel or titanium.
  • Manufactured as single or multiple bellows and can be combined into double expansion joints
