Why the metal expansion joint will burst open?
Author: source: date: 2016-09-22 15:11:11
The reason as below:
①Exceed the design pressure
②Exceed the design compensation amount
③Meatal expansion joint connected pipeline instability,caused the abnormal distortion of compensator.
④The error function selection of Axial expansion joint and horizontal expansion joint.
⑤Exceed the maximum working temperature
⑥No lifting the limit rod after installation.
⑦Corrosive media to use special corrosion-resistant material compensator
⑧When the internal sleeve reversed also may be case of explosion.
