Pressure balanced expansion joint

A pressure balanced expansion joint absorbs pipe movement (axial, lateral, angular) while neutralizing the internal pressure thrust, preventing it from loading sensitive equipment like turbines or pumps, and eliminating the need for heavy main anchors by using an opposing bellows system to create an equal and opposite force. It's crucial for high-pressure systems or tight spaces where large anchors are impractical, allowing for thermal expansion without damaging equipment or structures, often incorporating elbows or "T" shapes to manage directional changes.
