Expansion joints can be engineered to accommodate:

  • Axial compression and extension
  • Lateral movement
  • Angular movement
  • Thermal expansion and contraction
  • Pressure-related pipe loads
  • Vibration or pulsation where applicable
  • Complex combinations of piping movement

Available configurations include single-bellows, double-bellows, tied, hinged, gimbal, shrouded, externally pressurised and pressure-balanced arrangements, depending on the movement and restraint requirements of the piping system.

Features & Benefits

Engineered Movement Control

Metal expansion joints can be designed for axial, lateral, angular or combined movement, allowing the joint configuration to match the actual pipework movement rather than using a one-size-fits-all component.

Stainless Steel & High-Performance Material Options

Expansion joints and flexible piping assemblies can be engineered using stainless steels and other alloys selected according to temperature, corrosion, pressure, fatigue and process-media requirements.

Multiple Expansion Joint Configurations

Teddington provides single, double, tied, hinged, gimbal, externally pressurised and pressure-balanced expansion-joint arrangements for different piping layouts and restraint strategies.

Flexible End Connections

Depending on the design, assemblies can incorporate flanged ends, weld ends, threaded connections or bespoke interfaces to suit project piping and equipment.

Bellows Protection Options

Internal liners, external covers and protective shrouds can be incorporated where required to protect bellows from turbulent flow, mechanical damage, debris or environmental exposure.

Flexible Metal Hose Solutions

Flexible metal hoses provide movement and vibration flexibility for HVAC, industrial and fluid-transfer applications while offering pressure and temperature capability appropriate to the selected assembly.

Bespoke Engineering

Where standard configurations are unsuitable, Teddington can engineer expansion joints and bellows systems around project-specific pressure, temperature, movement, dimensional and material requirements.

Engineering Selection Information

For accurate selection of a Teddington expansion joint or stainless steel flexible connector, submit the following project information to Kinetics Middle East:

  1. Pipe diameter and required overall dimensions
  2. Design and operating pressure
  3. Design and operating temperature
  4. Fluid or process media
  5. Required axial movement
  6. Required lateral movement
  7. Required angular movement
  8. Expected operating cycles
  9. Required end connections
  10. Pipe layout and available installation space
  11. Anchor and guide arrangement
  12. Required materials
  13. Testing and inspection requirements
  14. Applicable project specifications or consultant requirements

Providing this information allows the expansion joint or flexible hose assembly to be selected around the actual piping duty rather than only nominal pipe size.

Installation Guidelines

Correct installation is essential for reliable operation of metallic bellows expansion joints.

Before installation, inspect the bellows and end fittings for transport or handling damage. Protect the thin-wall bellows convolutions from dents, scratches, welding arc strikes and weld spatter.

Do not force an expansion joint into a piping misalignment that was not included in its engineered movement capability. Torsional twisting of the bellows must also be avoided unless specifically included in the design.

Pipe anchors, guides and supports must be installed according to the engineered piping-system arrangement. Field changes to anchor or guide locations can alter the forces and movement acting on the expansion joint.

Where an internal flow sleeve is fitted, install the expansion joint in the correct flow direction.

Do not exceed the specified design or test pressure of the expansion joint.

For axial arrangements, only one axial expansion joint should normally be installed between two main anchors unless intermediate anchoring has been specifically incorporated into the engineered piping design.

For the applicable Teddington installation procedure, use the Kinetics product-page installation download and follow the project-specific piping drawings.

Frequently Asked Questions

What are Teddington metal expansion joints used for?

Teddington metal expansion joints are engineered to accommodate controlled movement in piping and ducting systems. Depending on the configuration, they can accommodate axial, lateral or angular movement caused by temperature changes, pressure conditions and other system movements.

What is the difference between a metal bellows and an expansion joint?

A metal bellows is the flexible corrugated element. A metal expansion joint is the complete engineered assembly, which may include one or more bellows together with end connections, liners, covers, tie rods, hinges, gimbals or other restraint hardware.

What are Teddington flexible metal hoses used for?

Flexible metal hoses are used where piping systems require flexibility to accommodate movement, vibration, thermal expansion or equipment connections. Applications include HVAC, industrial piping and fluid-transfer systems.

Can Teddington expansion joints accommodate axial, lateral and angular movement?

Yes. Different Teddington expansion-joint configurations can be engineered for axial, lateral, angular or combined movement. The correct configuration depends on the piping layout, required movement and restraint strategy.

Are Teddington expansion joints made from stainless steel?

Stainless steel is widely used for Teddington metal bellows and expansion-joint systems. Other alloys can also be selected for applications involving specific temperature, corrosion, pressure or process-media requirements.

Are bespoke expansion joints available?

Yes. Teddington provides both standard and bespoke engineered expansion-joint solutions for project-specific sizes, movements, pressures, temperatures, materials and connection requirements.

Are Teddington bellows manufactured in the UK?

Yes. Teddington states that its bellows are manufactured in the UK, with the company’s bellows and expansion-solutions experience dating back to 1927.

What information is required to select an expansion joint?

Selection should include pipe size, pressure, temperature, process media, axial/lateral/angular movement, expected cycle life, connection type, installation dimensions, anchor and guide arrangement, material requirements and applicable testing or documentation requirements.

Why are anchors and guides important for metal expansion joints?

Anchors and guides control pipe movement and the loads acting on a metal expansion joint. Incorrect restraint can expose the bellows to unintended movement or pressure thrust and can prevent the expansion joint from operating as designed.

Does Kinetics supply Teddington expansion joints in the UAE?

Application

Air Conditioning, Heating and Ventilating Systems:

Teddington connectors eliminate stresses caused by changes in temperature and piping misalignment, as well as reduce the transmission of noise and vibration. They are used on both hot and chilled water circulation lines, suction and discharge sides of pumps and header connections.

Sewage Treatment Plants and Pollution Control:

Teddington connectors are used extensively in sewage water treatment-plants and pollution-control systems.

Control Rod Applications:

Optional control rod assemblies are designed to absorb static pressure thrust developed at the connector, thus minimizing possible failure of the connector or damage to the equipment. When used in this manner, control unit assemblies are an additional safety factor, minimizing possible failure of the expansion joint or damage to the equipment.
1. Anchored Systems: Control rod assemblies are not required in piping systems that are anchored on both sides of the connector provided piping movements are within the rated movements.
2. Unanchored Systems: Control rod assemblies are always recommended in unanchored systems and when the maximum pressure and movement exceed the rated limit.
3. Spring-Mounted Equipment: Control rod assemblies are always recommended for spring-mounted equipment when the maximum pressure and movement exceed the rated limit.

Installation Guidelines

Inspect the expansion joint before installation and protect the bellows convolutions from dents, scratches, welding arc strikes and weld spatter. Do not force the joint into unintended piping misalignment and do not introduce torsional movement unless specifically included in the design. Install all anchors, guides and supports according to the approved piping-system drawings. Where an internal sleeve is fitted, observe the correct flow direction. Do not exceed the specified design or test pressure. For axial systems, do not install more than one axial expansion joint between two main anchors unless intermediate anchoring has been specifically engineered. Follow the Teddington installation instructions supplied with the product and refer any field changes in piping restraint or alignment to Kinetics Middle East before commissioning.
