Non-metallic compensator

Frequent users of non-metallic expansion joints with varying diameters, when making a purchase, will inform the salesperson of the required specifications.

Hebei Zhonghao Machinery produces and sells variable diameter non-metallic compensators, primarily used in power plant flue gas ducts to absorb thermal displacement and

(Vibration) Damping.
When purchasing a non-metallic bellows reducer, you will be reminded:
1. Outside dimensions of rectangular pipe (A x B)
2. Application Scenario
3. Medium temperature and pressure;

4. Connection methods and dimensions.

Non-metallic compensators, product performance parameters of rectangular compensators, for your reference.
1. Applicable Media: Air, flue gas, and dusty gases.
2. Pressure (P): -20 ~ 30 kPa
3. Operating Temperature (t): Refer to the above set working temperature, ≤450℃;
4. Compensation Quantity: Xo represents the axial compensation quantity, with a negative sign indicating compression deformation; Yo represents the lateral compensation quantity. The specific compensation quantity is as per the above.

As specified in the table;
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℃), materials 10 or

Q345(16Mn) should be treated as a special design if other materials are used.
b. Non-metallic belt and grommet materials, commonly using glass fiber fabric and polytetrafluoroethylene film, depending on different working temperatures.

Composed of materials such as composite rubber, glass fiber cloth, and aluminum silicate fiber cotton. Asbestos-containing materials are not permitted for the production of non-metallic items.

Compensator.
6. Connection Method: Default is socket weld, meaning the pipe is inserted into the compensator's interface, with an insertion depth of 20mm. Alternatively, it can be done by...

Lan connection, at this point, the product length and compensation are the same as the insert welding pipe form.
