應用Application:

1.兩端都有工作波紋管，中間有一個平衡波紋管，補償器通過受力構件來承受內壓推力。

2.補償管系的軸向位移，內壓推力自身平衡。

3.一般應用在架空直管線上，水平安裝。

1. Both sides have the bellows, also there is bellows in the middle. The compensator withstands the intrinsic pressure force through the stress component..Absorbing axial movement and balancing the internal pressure.

2. The axial displacement compensation control system, the interal pressure keep their balance.

3. Normally used in overhead staraight lines, horizontal installed.
