How to disassemble a rubber flexible joint?

When disassembling Rubber Expansion Joints, the following methods can be employed:

1.Disassembly Using the Lever Principle: Use a crowbar to pry open a small notch at the edge of the Rubber Joint. Repeat this process at intervals of several centimeters to gradually pry open the Flange. This method is simple but relies heavily on personal strength and carries risks such as scratching the joint.

2.Disassembly Based on the Joint Installation Method: Rotate the ball and flange to a semi-separated state. Use external force (such as a hammer or crowbar) to squeeze and complete the separation. This method causes less damage to the rubber part of the joint but requires a certain degree of skill and experience.

3.Disassembly Using Mechanical Equipment: This method is suitable for threaded Rubber Joints, where mechanical equipment is used to forcibly pull apart the flanges through its stretching effect. However, this method may not be suitable for all types of rubber joints as it may cause damage to the ball.

Precautions for Disassembly:

Before disassembly, ensure that the medium inside the Rubber Soft Joint is fully drained. Especially for corrosive media, rinse with clean water to prevent harm to personnel or the environment.

When disassembling, arrange and mark the removed parts in order to facilitate reinstallation in the original sequence. Handle the parts gently to avoid bumps, drops, or deformation.

During maintenance, lock the power switch and install blind plates on the material pipelines to prevent accidental startup or opening.

Adhere to relevant safety operating procedures and wear appropriate protective equipment when necessary.

If you are unfamiliar with the specific operation or concerned about safety issues during the disassembly process, it is advisable to consult professional personnel for guidance.
