Twin sphere union rubber expansion joint is composed of inner and outer rubber, reinforcement layer, vulcanized composite model and parallel metal joints. Wire-fastened rubber joints can also be made of different materials depending on the medium through which they flow.
Working Principle:
Composed of multiple rubber expansion joints connected together, enhancing displacement compensation capabilities and system stability.
Function Summary:
Large displacement compensation
Improved pipeline flexibility
Suitable for complex operating conditions
Application Scenarios:
Long-distance pipelines
Heating pipelines
Large industrial facilities
Pipeline systems with significant vibration
