Abstract
Tubería de diámetro interior grande hecha de material sintético termoplástico, especialmente tubo para colocación en tierra, que consta de un perfil hueco de material sintético enrollado en forma de arrollamiento en espiral cuyas espiras se tocan una con otra junto a las superficies laterales del perfil hueco y son soldadas con ayuda de una costura a tope, mientras que las paredes libres del perfil hueco se complementan una con otra para formar la pared interior del tubo o la pared exterior del tubo, teniendo el perfil hueco de material sintético una sección transversal exterior rectangular, pero una sección transversal interior en lo esencial con forma circular, caracterizada porque las paredes laterales del perfil hueco de material sintético soldadas para formar la costura a tope, son más delgadas en aproximadamente 50% que las paredes libres del perfil hueco, y porque las paredes libres del perfil hueco estan estructuradas de un modo tal que, en el caso de solicitaciones por flexión queactúan sobre el tubo colocado en tierra, las tensiones de deformación no superan a la resistencia mecánica de las costuras a tope.
