Novel thermoplastics and pipes made therefrom which can withstand extreme surface and/or internally generated pressures that make them excellent candidates for uses such as within underground liquid and gas transport systems are provided. Such pipes are improvements over standard metal (i.e., steel, copper, lead, and the like), concrete, ceramic, and the like, pipes due to toxicity issues (such as with lead pipes), raw material costs (such as with copper), 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 thermoplastics exhibit excellent long-term hydrostatic strength characteristics that permit potential long-term reliable usage in such underground conditions and are preferably made from resins that include nucleating agents that provide such needed properties therein.
