应用Application:

1.两端都有工作波纹管，中间有一个平衡波纹管，补偿器通过受力构件来承受内压推力。

2.补偿管系的轴向位移，内压推力自身平衡。

3.一般应用在架空直管线上，水平安装。

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.
