MULTI-LAYER TUBES OR CONDUITS AND MANUFACTURING METHODS THEREFOR

摘要

By advancing a plurality of independent layers or profiles onto a rotating mandrel, and continuously bonding the layers or profiles together, an elongated, hollow, large diameter, multi-component and/or multi-layer tube or conduit is achieved. A wide variety of various materials, forms, profiles, composites, and components can be employed to produce the desired multi-component/multi-layer tube or conduit of the present invention. In this way, the multi-component and/or multi-layer tube or conduit is constructed possessing specific physical and structural attributes particularly suited to the needs of one or more industries or technological areas. As a result, prior art expensive manufacturing methods are completely eliminated and an effective, cost-efficient, multi-component/multi-layer tube or conduit having precisely desired requirements is realized.
