Abstract
A invenção refere-se a um método para a manufatura de tubos plásticos, do tipo de acordo com o qual uma peça em bruto de tubo levada até uma temperatura próximo à sua temperatura de orientação molecular é submetida a alongamento biaxial como resultado da expansão radial da peça em bruto de tubo dentro de um cilindro de formação, o diâmetro interno do qual é igual ao diâmetro desejado para o tubo plástico, com a exceção da expansão térmica, com a formação de uma bolha em uma extremidade do tubo e deslocamento controlado dessa bolha tão distante quanto a outra extremidade do tubo, e com alongamento longitudinal. A expansão radial é realizada em pelo menos duas fases, a saber: uma primeira fase, durante a qual a peça em bruto de tubo é inflada até um diâmento intermediário determinado por um invólucro de parede dupla introduzido no cilindro de formação, com um fluido quente circulando entre as duas paredes do invólucro, e, subseq³entemente, o invólucro é retirado progressivamente do cilindro de formação com a finalidade de, durante uma segunda fase, permitir a expansão radial do tubo plástico até o diâmetro interno do cilindro de formação, e o alongamento longitudinal do tubo, e o cilindro de formação são resfriados externamente.
