    • A method of forming a molded article and a molded article itself having a passage therein which has a cross-sectional dimension adjacent an end which is less than at a location which is spaced from the end are disclosed. In the method an elongate, rigid mandrel is covered over a substantial portion of its length with a flexible mandrel. The flexible mandrel, when covering the rigid mandrel, has an exterior surface which has a cross-sectional dimension which is less adjacent an end thereof than at a location which is spaced from that end. The flexible mandrel is then covered with a material which is to form the molded article with the rigid and flexible mandrels defining the mold about which the article is formed by the material. The material is then set to form the molded article about the mandrels with the mandrels defining the passage in the molded article. The mandrels are then removed from the molded article from the end of the passage which has a cross-sectional dimension which is less than at the location which is spaced from that end.

    • Novel thin-walled thermoplastic or thermoset pipes of at most 5 millimeters in thickness which can withstand a varied range of internally generated and/or applied pressures up to at least 5 bars, preferably at least 20 bars, for utilization within, primarily, liquid transport systems. Such pipes are improvements over standard metal (i.e., steel, lead, and the like) pipes due to construction costs, shipping costs, implementation costs (particularly underground), flexibility (and thus modulus strength allowances) to compensate for underground movements (i.e., earthquakes and tremors), non-rusting characteristics, reduced crack propagation possibilities, and ease in manufacture. Such pipes are preferably reinforced with specific textile reinforcement materials that permit a lower thickness of plastic to be utilized than is generally required to withstand high pressure situations and also serve to prevent propagation of any cracks which may develop within the thermoplastic or thermoset materials. Such pipes exhibit an elongation at break in relation to that provided by the textile reinforcement and not with regard to the same type of elongation at break characteristic for the thermoplastic or thermoset composition.
