Correct installation method of rubber expansion joint!

Rubber expansion joints are an important component used in piping systems that absorb the expansion and contraction of pipes due to temperature changes or vibrations, thereby protecting the pipes from damage. Here are the general steps for properly installing a rubber expansion joint:

1.Safety measures:

Before starting the installation, please make sure to take appropriate safety measures, such as wearing personal protective equipment such as gloves and safety glasses.

2. Check the expansion joint:

Confirm whether the purchased rubber expansion joint meets the project requirements and specifications, and ensure that there is no damage or defect.

3. Prepare the work area:

Clean the work area to ensure the surface is flat, clean and free of sharp objects or debris.

4. Installation position:

Determine the installation position of the rubber expansion joint, usually installed between two sections of pipes.

5. Place gaskets:

Install gaskets on the flanges on both sides of the rubber expansion joint to ensure a tight seal. Gaskets are usually rubber or plastic.

6. Fix flange:

Connect the flange of the rubber expansion joint to the flange of the pipe, make sure they are aligned and tighten with bolts. Please follow the installation specifications provided by the flange manufacturer.

7. Adjust the bolts:

Tighten the bolts gradually and evenly to ensure that the rubber expansion joint is evenly compressed. Don’t make one side too tight or too tight.

8. Check the flange connection:

Check whether the flange connection is tight and there is no leakage. If necessary, use a wrench or torque wrench to adjust the bolt tightness.

9. Exhaust:

After completing the installation, open the duct system and ensure that the air is exhausted from the system to prevent air locking.

10. Monitoring:

Regularly monitor the performance of rubber expansion joints to ensure their normal operation. Check for damage, cracks, or other problems, and clean them regularly to prevent buildup from clogging.

Please note that the installation method of rubber expansion joints may vary for different applications and models, so it is recommended to refer to the manufacturer’s specific installation guidelines before proceeding with installation. Additionally, make sure all staff have the appropriate training and experience to ensure a proper and safe installation.
