Abstract
CONDUCTO COMPUESTO POR UN TUBO DE MATERIAL PLASTICO Y UNA CAPA DE BARRERA CONTRA LA DIFUSION DE OXIGENO A TRAVES DEL PLASTICO, UTILIZABLE EN SISTEMAS DE CALEFACCION Y DISTRIBUCION DE AGUA. LA CAPA DE BARRERA ES UN HOJA METALICA Y ESTA UNIDA AL MATERIAL PLASTICO A INTERVALOS ESPACIADOS LONGITUDINALMENTE A LO LARGO DEL TUBO, SIENDO LAS UNIONES CIRCUNFERENCIALES Y DE TAL MANERA QUE ENTRE ELLAS TIENEN LUGAR EXPANSIONES Y CONTRACCIONES DIFERENTES ENTRE EL TUBO Y LA CAPA DE BARRERA. ESTA CAPA VA PROVISTA, EN AL MENOS UNA DE SUS SUPERFICIES DE UNA CAPA DE ADHESIVO SENSIBLE AL CALOR Y COMPATIBLE CON EL MATERIAL PLASTICO DEL TUBO. SE DESCRIBE TAMBIEN UN APARATO PARA FABRICAR EL CONDUCTO.
