Fabric Expansion Joints – Product Lines
ECO LINE High quality Expansion Joints for Low Temperatures
“Cost-Effective Quality”
ECO Line Expansion Joints are recommended for low-temperature applications in
plant installations, where the ability to absorb vibration is required. ECO Line
Expansion Joints have different design and construction characteristics: single Layer or
two- layer configurations of first range special materials, additional reinforcement in
the attachment zone are few of the available solutions for your specific requirements.
Comdiflex has developed special designs which combine the ability of vibration and
movement absorption, especially suitable for ventilation and extraction systems.
Temperature Range: -40ºC to 200ºC
HIGH TECH LINE Multi-Layers Versatile Expansion Joints for High Temperatures
“Resistance, Adaptability and Versatility”
Comdiflex HIGH-TECH Line includes a range of multi-layer expansion joints suitable for
applications with high temperatures and heavy conditions. Mechanically robust
compensators, elaborated from the last generation technical fabrics are developed
especially for demanding applications, where resistance and ability to compensate
large movements are required.
Additional insulation pillows can be used to protect the flexible element from the
system’s heat and prevent fly ash from filling the gap between the compensator and
metallic deflector.
Temperature Range: up to 1000ºC
INNOVA LINE Maximum Resistance Expansion Joints for Highly Demanding Applications
“Custom Made Solution for Extreme Conditions”
Comdiflex INNOVA Line products are engineered and manufactured using special
technical fabrics and particular metal/PTFE foils in order to provide excellent
resistance in highly aggressive applications with extreme temperatures or corrosive
fluids.
Our highly skilled and experienced engineering team develops custom made solutions
for wide range of critic situations. Special “extra reinforced” types are available for
large movements and special extra-resistant models for corrosive applications.
Fabric Expansion Joints – Types of Fastening
⋅ Expansion Joints with different types of connections on each side
⋅ Expansion Joints with variable dimensional forms (circular to rectangular and vice versa)
⋅ Special “Extra Reinforced Types” engineered for extra intense axial and lateral movements
