Before we install the steel culvert
, we need to keep clear of the model, standard and pipe arrangement condition, and assure the length. The compensator of the draft tube should have the flow direction mark. When we install the steel culvert
, it is not allowed the welding slag splash on the surface of the steel culvert and any damage is not allowed. In order to ensure the normal operation of the steel culvert
compensator, the guiding pipe shelf must surround on the pipeline.
