Pressure balanced expansion joint for a blast furnace pipe in a steel mill.
Multi-ply expansion joint, the inner layer are mad out of Inconel 625, as a protection of corrosion. Including a permanent leakage control of the first two layers of the bellows. Refractory lined to reduce the temperature on the expansion joint.
Pressure: 2.6 bar g Temp: 250 °C (reduced through refractory) Movements: -55 mm axial, +/- 0.15 ° angular
