Installation Instructions for French Expansion Joints
Published time:
2024-12-15
After the loose expansion joint is installed on the pipe, the nut and elastic sealing ring are tightened. Under the action of the nut cover, they are inclined to each other and tightly pressed against the outer circle of the pipe to achieve sealing and connection. When the temperature changes, the pipe can freely expand and contract in the middle of the joint. When the foundation subsides, the pipe can deflect and ensure that the seal is leak-proof, thus achieving automatic compensation.
