Pressure balance type expansion joint
Pressure balance type expansion joint a job at each end of the corrugated pipe, expansion joint force members (big by rod or tongue tube) to bear inner pressure thrust, so tube system just middle fixed bracket.
Straight pipe pressure balance type theinflation festival only absorbs axial displacement
Nominal pressure: (Mpa) 0.25 ~ 1.0
Nominal diameter: DN100 ~DN2500
