Abstract

PROCEDIMIENTO DE FABRICACION DE TUBOS ESTRIADOS INTERIORMENTE EN FORMA HELICOIDAL. CONSISTE EN EL ESTIRADO DE UN TUBO, DE DIAMETRO Y ESPESOR SUPERIOR AL DEL TUBO A OBTENER, A TRAVES DE UNA HILERA, HABIENDO INTRODUCIDO PREVIAMENTE EN EL TUBO UN MANDRIL QUE TIENE UNOS SALIENTES DE COMPONENTE HELICOIDAL, POR LO QUE, AL AVANZAR EL TUBO SE PROVOCA EL GIRO DEL MANDRIL, EN LO QUE SE OBTIENE EL ESTRIADO DEL INTERIOR EN TODA SU LONGITUD. INICIALMENTE, A CADA TUBO SE LE REALIZA UNA PUNTA DE ESTIRAJE QUE PERMITE SU INTRODUCCION EN LA HILERA Y SE LE DA EL TRATAMIENTO QUIMICO ADECUADO PARA OBTENER SUPERFICIES DESOXIDADAS.
