HDPE Pipelines are usually used for intake lines in seawater treatment plants, cooling plants, etc. or as outfall pipes for storm water or sewage system, etc.
The HDPE submarine pipeline is designed to be buoyant with the anchor collars attached and the pipe filled with air and to be strongly negatively buoyant when it is subsequently filled with water. Air is contained in the pipe by means of a sealed and plug or plate securely attached to the end of the pipe.
