The way a non-metallic compensator is installed depends on its type, application scenario, and the specific requirements of the piping system. To ensure proper installation and peak performance, here are some common non-metallic compensator installations and their considerations:
1. Flanged connection
Scope of application: Almost all types of non-metallic compensators can be flanged.
Installation Steps：
Verify that the compensator matches the flange size of the piping system and check that the flange surface is flat and undamaged.
Align the flanges at both ends of the compensator with the pipe flange, using bolts and spacers to connect.
Tighten the bolts evenly to the torque values provided by the manufacturer, ensuring a tight connection and a good seal.
Precautions：
Avoid overtightening the bolts to avoid damaging non-metallic materials or causing seal failure.
If the media is corrosive, select a suitable corrosion-resistant gasket material.
2. welded connection
Scope of application: Commonly used in certain specific types of FRP (glass fiber reinforced plastic) compensators, especially large bore pipe systems.
Installation Steps：
Confirm that the model and specification of the compensator meet the design requirements before installation.
Weld the compensator directly to the pipe using the appropriate welding process and technical parameters, pay attention to the welding quality and ensure the welding strength and tightness.
Avoid welding slag splashing to non-metallic surfaces during installation to prevent material damage.
Precautions：
For non-metallic materials, special care should be taken when welding to avoid damaging the material by overheating.
Strict inspection is required after welding to ensure that there is no risk of leakage in the welded parts.
Maintenance recommendations
Periodic inspection: Establish a periodic inspection system to find and deal with scratches and cracks on the surface of the compensator in time.
Cleaning and maintenance: Keep the compensator and its surrounding environment clean to avoid foreign matter entering and affecting the normal operation; For some types of non-metallic compensators, care should also be taken to prevent grease contamination 。
Replacement frequency: According to different use conditions, reasonably plan the replacement cycle of compensator, especially those components under bad working conditions, such as sealing rings, gaskets, etc.
Record keeping: After each maintenance, record relevant information in detail, including problems found, actions taken and replaced parts, etc., for future reference and traceability.
By following the above installation methods and precautions, the safe and reliable operation of the non-metallic compensator can be effectively guaranteed, and its service life can be prolonged. Proper installation is key to ensuring that the compensator works properly, so it must be performed strictly in accordance with the specifications.
