Abstract

Описано применение, по меньшей мере, частично поперечно связанного полиолефинового пластика, который ориентирован по двум осям, в качестве материала для напорных труб. Напорную трубу изготавливают посредством экструзии с последующей осевой и периферийной ориентацией трубы, при этом труба, по меньшей мере, частично поперечно связана перед ориентацией по двум осям. Предпочтительно, чтобы труба перед ориентацией была поперечно связана примерно на 20-50%. Посредством, по меньшей мере, частичной поперечной связи перед ориентацией последняя может быть осуществлена при температурах выше точки плавления кристаллов пластика.Международная заявка была опубликована вместе с отчетом о международном поиске.
