EXPANSION
JOINTS
Textile expansion joints are flexible connections, the purpose of which is to absorb vibrations and compensate for movements between the pipe sections to which they are connected.
The appropriate expansion joint model, as well as the correct choice of materials, will depend on the characteristics of each specific installation.
In order to respond to the different requirements of each application, multiple different designs and construction forms have been developed. An appropriate selection can respond to a large number of demanding requirements, save costs and help protect the environment, which together make them a critical component for your industry.
General characteristics:
- Resistance to a wide range of temperatures
- Pressure resistance
- Resistance to corrosion and different chemical agents
- Adaptability to different duct movements
- Reduction of noise and vibrations, etc.
“High-versatile, engineered and taylor made expansion joints”
Textile expansion joints, manufactured by Comdiflex, are the result of more than 20 years of research and experience in solving expansion problems inherent to the needs of different types of current industry such as: thermal power plants, combined cycle plants, chemical and petrochemical plants, cement industry, mining…
Comdiflex provides technical solutions for:
- Absorption of movements and vibrations.
- High tightness.
- Resistance to aggressive fluids.
- Thermal/acoustic insulation requirements, etc.
In order to select the appropriate compensator model and materials, in addition to the basic criteria to be taken into account such as temperature, pressure and types of movement, other additional parameters must be considered such as:
ambient conditions,
- moisture content,
- existence of vibration,
- expected cycles,
- available space,
- standards to be met,
- supports, anchors, guides…
In order to respond to the different requirements of each application, multiple different designs and construction forms have been developed.
Advantages
Textile expansion joints absorb movements in any direction, whether axial or lateral, and even torsional movements, compared to metal expansion joints that only absorb axial or lateral movements and never at the same time.
This is mainly due to its low weight, which means lower transport and installation costs.
Circular, rectangular, conical, with or without flanges, with flanges of different sizes, each end with a different form of fastening, etc.
The multi-layer design and high-performance materials (for high temperatures, anti-wear, anti-corrosion, etc.) ensure a long life. This leads to significant economic savings, since maintenance cycles are longer.
Availability of materials especially resistant to corrosion.
TEXTILE EXPANSION JOINTS ECO LINE
Expansion joints for non-demanding environments
“Profitability of a guaranteed quality”
ECO Line expansion joints are recommended for low temperature applications in installations with non-demanding requirements. The ECO line comprises a series of designs with different characteristics: single or double layer models made of the highest quality materials, with different additional protective reinforcements in the fastening area, in custom sizes and shapes that allow for perfect adaptation to the most diverse requirements, with the best quality/price ratio.
Within the ECO Line, Comdiflex has developed special designs that combine the ability to absorb both vibrations and movements, especially recommended for use in fan and extractor installations.
The temperature range is from -40 to 200°C
Advantages of ECO Line
- Economically profitable
- Low rigidity
- No size limits
- Low temperature resistance
- No limits on cross-section geometry
- Low weight
- Easy to transport and assemble
TEXTILE EXPANSION JOINTS HIGH-TECH LINE
Expansion joints for high temperatures and demanding applications
“Resistance, Flexibility and Versatility”
The High-Tech line incorporates a series of multi-layer compensators specially developed for operation in high temperature applications and severe conditions. They are mechanically robust products made from high-performance materials. The design can include additional protection elements such as insulating packages made of ceramic fibre or mineral wool that offer additional protection to the compensator, improving its performance by preventing the accumulation of particles between the metal jacket and the compensator. The temperature range is up to 1000°C. The temperature range is from -40 to 200°C.
Commonly used in:
- Thermal power plants
- Cement plants
- Steel industry
- Gas turbines
- Incinerators
- Petrochemical industry
Advantages of HIGH TECH Line
No limits on size or cross-section geometry
- Resistant to corrosion
- Corrects construction misalignments or errors in movement calculations
- Resistance to low temperatures
- Resistance to noise and vibrations
- Low rigidity
- Easy to transport and replace
TEXTILE EXPANSION COMPENSATORS INNOVA LINE
Expansion joints for very aggressive media
“Custom-made expansion joints for extreme conditions”
The expansion joints of the INNOVA line from Comdiflex are manufactured using specialised PTFE-based materials with the aim of offering excellent chemical resistance to both acidic and alkaline substances. Our highly qualified technical team develops expansion joints according to the specific needs of each client, finding the solution to the most demanding and severe requirements. Special designs, extra reinforced or with pre-formed waves, offer perfect resistance to sudden or simultaneous movements, conditions with extreme temperatures and/or the existence of corrosive fluids.
In addition to the classic models, Comdiflex has developed additional types of expansion joints for special service conditions, both geometric and technical.
- Expansion joints with different connections on each side
- Variable dimensional shape expansion joints (reduction from circular inlet to rectangular outlet and vice versa)
- Special types for extreme conditions: strong simultaneous axial and lateral movements, with the existence of vibrations, high temperature and pressure.
Fabric expansion joints, manufactured by Comdiflex, are the result of more than 20 years of research and experience in solving expansion problems inherent to the needs of different types of current industry such as: thermal power plants, combined cycle plants, chemical and petrochemical plants, cement industry, mining…
