1. Applicable Medium: Air, flue gas, and dusty gas.

2. Pressure (P): -20 to -30 kPa

3. Operating Temperature (t): Refer to the above set working temperature, ≤450°C.

4. Compensation Volume: Xo represents the axial compensation volume, with a negative sign indicating compression deformation; Yo represents the lateral compensation volume. The specific compensation volume is as specified in the table above.

Material

a. Metal structural components are typically recommended to use materials with a temperature rating of t≤400°C, such as Q235-A. For temperatures up to 450°C (t≤450°C), materials 10 or Q345 (16Mn) should be used. Other materials should be considered for design purposes.

b. The compensator features a non-metallic ring and a gasket layer made from various materials, such as glass fiber cloth, polytetrafluoroethylene film, composite rubber glass fiber cloth, and silica-alumina fiber cotton, depending on the working temperature. Asbestos-containing materials are not permitted for manufacturing non-metallic compensators.

6. Connection Method: Default is insert welding, where the pipe is inserted into the compensator's interface with a 20mm insertion depth.法兰 connection is also available, in which case, the product length and compensation are the same as the insert-welded pipe. Compensators are divided into metallic and non-metallic types. The elastic element that constitutes the main working body of the compensator is made of non-metallic material, typically fiber fabric, hence also known as fabric compensators (expansion joints, flexible joints). There is also rubber material, which can replace fiber fabric in all other working conditions except when high temperatures (above 400°C) are involved.
