The limit rubber expansion joint device is an ideal substitute for the steel force transmission joint. Rubber expansion joint with tie rod is used in a reasonable combination, and also plays a role of limiting the displacement, using the limit device and transmitting force. Rubber joints can be used to limit the amount of displacement when used in general piping connections or in pipeline lines where displacement is required.
Working Principle:
Limit rods are added to the rubber expansion joint to restrict maximum displacement and prevent overstretching or overcompression.
Function Summary:
Prevents pipeline accidents
Withstands a certain internal pressure thrust
Improves system safety
Application Scenarios:
High-pressure pipelines
Pump outlets
Vertical pipelines
Applications with high safety requirements
