What are the methods of replacing the skin part of the non-metallic compensator?

Non-metallic compensator is also called fan soft connection. Non-metallic expansion joint is mainly composed of non-metallic skin. Metal frame. Guide plate. Steel wire mesh. Fan import and export commonly used insulation materials, can absorb the thermal expansion of the pipeline, play a role in vibration and noise reduction.
If the skin of the non-metallic compensator is damaged, if the metal frame is intact. The user only needs to replace the non-metallic skin. Let us understand the method of replacing non-metallic compensator skin cloth.
If the user knows the working pressure of the non-metallic compensator. Media. Size. Compensation and other technical parameters, tell the manufacturer at the time of ordering and make a new skin cloth according to the original dimensions. First remove the damaged skin. Remove the fixing bolt or self-tapping wire with a screwdriver or wrench, while removing and saving. If it can be used again, mark it in order. Wait until the production of new non-metallic skins is finished. After the production of the non-metallic skins, check and confirm the outer diameter of the non-metallic skins. Replace the technical parameters and the installation position to make sure the requirements are met. The steps are as follows.
1 . Prepare the previously removed pressure bar, usually use the fastening bolt itself has rusted, if there is bad need to replace.
2 . Check whether the non-metallic compensator pressure plate opening position deviates from the flange opening and whether the metal frame can continue to use.
3 . Install the inner skin cotton, set the insulation nails separately, install the inner layer of insulation cotton wrapped with stainless steel wire mesh, and then install other insulation cotton in turn, and fix the flat with insulation nails.
4 . To avoid wrinkles, the non-metallic skin must be flat against the flange surface of the metal structure. After tightening, tighten with pressure plate and bolt. The whole installation process must start from the bottom to the top. From the bottom to the outside to prevent wrinkles.
5 . When the non-metallic compensator is level with the flue, the layer non-metallic skin interface should be pressed down the interface to prevent the interface from seepage.
6 . After replacing and making sure the installation is correct, tighten with a wrench. It is recommended to use electric wrench. Tighten in place and strictly prohibit leakage.
