As the important parts of metal corrugated pipe, the metal ripple compensator installation needs more attention.
The compensator do not absorb the torque, so it is not allowed to make the compensator torqued. During installation of compensator with draft tube, the river diversion should be accordance with medium drifting direction. We need to leave more space to install it, and do not stuck or limit its normal operation. When we install compensator, we need to protect the metal corrugated pipe from the welding slag.
