EXPANSION JOINTS

Several decades ago, when Kempchen first began producing soft-material expansion joints, metal expansion joints were still predominantly being used in the field of power plants and chemicals.

Today, KLINGER Kempchen soft-material expansion joints have found a solid range of applications. Without these versatile assembly parts, modern industrial plants would not be possible. With­out the use of soft-material expansion joints, the costs of such plants would be considerably greater.

The main advantage of soft-material is the multidimensional absorption of movement despite having very low reaction force. Their superior movement absorption al­lows for cost-effective piping, while their low reaction force perwiths cost-effective fix point construction.

KLINGER Kempchen has developed a patented method for sintering PTFE sheets onto all types of fabrics. This has brought signifi­cant improvements to the properties.

Design 1 with rotating flanges

Highly elastic pipe connectors
For all sectors of industry, apparatus and pipeline construc­tion, power plants, shipbuilding, fuel pumps, heating, cli­mate control and ventilation plants, etc.

Use
Absorption of axial and radial expansion, noise, vibrations and oscillations. For subsidence of buildings and containers, assembling imperfections, for electrical insulation, for nearly total noise absorption in pipelines, domestic supply mains, heating sys­tems, pump and motor connections.

Design 2

KLINGER Kempchen rubber fabric expansion joints with an extremely robust design for use in pipeline construction, shipbuilding, aggregate and power plant construction. Due to the flow-favourable bulge, they may be used both horizontally and vertically.

Metal expansion joints
Used to compensate for pipe expansions, as vibration dampers, as installation expansion joint for non-flooding pipes or to facilitate installation of pipe fittings.
The core piece is the parallel corrugated, twist-free metal bellows, mainly made of stainless and acid-resistant steel alloys.

Materials
The standard versions of the steel bellows expansion joints consist of a stainless steel bellows made of materials 304ss – 316ss and 321ss with connecting parts made of carbon steel.
The expansion joints can also be manufactured from other stainless alloys and, for higher temperatures, from highly heat-resistant alloys 1.4828, Inconel, Hastelloy and the like.

Area of application
All expansion joints, which have neither an inner guide tube nor an outer protection tube, can absorb axial, angular and lateral movements as well as vibrations. Therefore, these types have a very versatile application and can be used for practically all cases.

Temperature
The permissible temperature of the standard versions with connecting parts made of carbon steel is up to +400 °C.
At higher temperatures, the connecting parts must also be made of alloyed steel.

KLINGER Kempchen has developed chemically and thermally dura­ble fabric expansion joints for flue gas desulphurisation (FGD) waste incineration and chemical plants:
» ReaFlex for temperatures up to 205 °C
» ReaTex for temperatures above 260 °C

ReaFlex Elastomer Expansion Joints
are manufactured from elastomer bands reinforced with wire mesh, wire weave or fabric fibre glass. They are available in U-shape or band type for circular or angular ducts. For angular ducts, expansion joints can be manufactured with or without a bulge in the edge area. The design with a preformed bulge shows increased axial move­ment compensation.

ReaTax Fabric
are manufactured from PTFE coated glass fabric fibres. This combination of materials has shown superior performance at media temperatures of up to 260 °C. No pre-insulation is necessary at temperatures below this point. For higher temperatures, inner pre-insulation must be installed. Outer insulation is not permitted.
