expansion joints
Bording tissue expansion joints
The Bording fabric expansion joints are highly flexible, allowing for relatively large movement to be compensated for in a short installation length. Tissue expansion joints are only suitable for gaseous media such as flue gas and air.
A fabric expansion joint is always customized where the composition of the assembly is chosen based on the temperature and medium composition. We can also supply a flue valve with the expansion joints already assembled.
Functioning of tissue expansion joints
The operation of fabric expansion joints is based on temperature degradation over the various tissue layers. Therefore, the temperature on the outside of the expansion joint should never exceed 50°C. The pressure resistance of fabric expansion joints is low. In this way, the application is limited to flue gas (exhaust) and air systems.
We are happy to help you select the right solution and material composition
Versions
The Bording fabric expansion joints are available in 3 different designs:
Implementation I
Mounting directly on the pipe (with clamping bands). Up to 350°C max.
Implementation II
Fastening by means of flanges. Up to 350°C max.
Implementation IV
Mounting on L-profiles with a bolted connection. Up to 1100°C max.
Depending on the temperature, we distinguish between "LT" fabric expansion joints and "HT" fabric expansion joints. The Bording LT compensator series Low Temperature range) consists of various types of compensators for temperatures up to 350°C. These are:
Type L: multilayer fabric expansion joints for clean air
TypeLTF: single-layer expansion joints for condensing flue gas (aggressive chemicals!)
TypeR: multilayer fabric expansion joints for dry flue gas.
The Bording HT compensator series (HighTemperature range) is, due to the temperature, only available in version IV and consists of two types of compensators for temperatures between 350°C. and 1100°C. These are:
Type L: multi-layer material structure for clean air
TypeR: multi-layer material structure for dry flue gas.
