Expansion Joints

LBH offers a series of standard types of Fabric Expansion Joints along with a numerous of special designs. Custom made Fabric Expansion Joints are available in all sizes and shapes for any application – from single bellows for ventilating systems to highly advanced multilayer expansion joints for gas turbine exhaust (see below). The common factor is always the craftsmanship, the use of superior materials and knowing their forces and limitations.

The LBH manufacturing range of Fabric Expansion Joints consists of 26 standard types divided into five categories. These cover a wide range of conditions, which also can be altered to fit special needs. The temperature capability ranges from -50⁰C to 1000⁰C and the pressure ranges from -50kPa to 50 kPa.
Type LN For clean air systems
Type MN For flue gas with a low acidcontent / limited mechanical conditions
Type RN For flue gas with a high acid content / severe mechanical conditions
Type HD For applications requiring optimal resistance against chemical attacks / mechanical conditions
Type GTX For Gas Turbine applications (See more below)


The innovative design solutions introduced with the GTX-range have been achieved through several years of in-house and on-site testing, involving intensive use of FEA-analysis. Gas Turbine Exhaust Expansion Joints are available in a variety of frame designs and fabric materials. Below you will find the three standard GTX fabric designs:

GTX-A: This fabric is used in applications that have no pressure pulses and have fairly smooth flow velocities. The design is typically used on units installed down stream of the turbine, after the diffuser sections where the gas flow characteristics have smoothed.

GTX-B: This is the most commonly used fabric design that will withstand normal pressure pulses and flow conditions. A unit composed of fabric can be installed e.g. at the bypass outlet sections or after the diffuser sections.

GTX-C: The GTX-C design is recommended for heavy-duty gas turbine exhaust applications where high-pressure pulsations with turbulent flow conditions exist.

For an optimal GT solution our well proven frame designs ensures long life time.

All standard GTX designs can be modified to suit any customer requirements through proper craftsmanship.
