Description
An inline pressure balance expansion joint absorbs axial movement while internally canceling out pressure thrust, so the pipeline’s own anchors don’t need to resist that force.
It works by combining a flow bellows with a balancing bellows of larger diameter connected via tie rods, so the pressure thrust forces balance each other internally rather than pushing outward on anchors and supports.
Engineered per project pressure and movement requirements, in stainless steel or carbon steel construction.
Key benefits
- Eliminates or greatly reduces pressure thrust on anchors
- Enables axial movement absorption in high-pressure systems without heavy anchor design
- Reduces overall structural/support costs on long pipe runs
Typical applications: High-pressure steam lines, straight pipe runs where anchor reinforcement is impractical, refinery and power plant piping.
