MULTILAYER COMPOSITE WASTE TUBE

摘要

According to the present invention, a waste tube with component layers is provided. An inner layer resisting at least one waste material system chemical and an outer composite wrapping layer each runs along the length of the waste tube. The impact zones of the waste tubes, defined by bends, tapers or junctions incorporated in the tube, are reinforced by an elastomeric barrier layer over an outer face of the inner layer and an impact absorption layer over the elastomeric barrier layer, wrapped by the outer composite layer. In another aspect, a method of manufacturing the waste tube is provided where a preformed tubular liner for building the component layers functions as the inner layer in the waste tube.
