Abstract

SE TRATA DE LA UNION DE DOS TUBOS (12, 14) CON UN REVESTIMIENTO (16, 18) DE POLYOLEFIN, COMO ES EL CASO DE POLYTHENE. LOS TUBOS ESTA SEPARADOS Y EL REVESTIMIENTO SOBRESALE DE ELLOS Y SE UNE A SU COMPAÑERO POR FUSION (20). LOS TUBOS ESTAN INTERCONECTADOS POR UN ARMAZON (24, 26, 28) Y UNA LECHADA DE CEMENTO EPOXY (34) RELLENA EL ESPACIO QUE QUEDA ENTRE EL REVESTIMIENTO Y EL ARMAZON. EL REVESTIMIENTO ESTA INSERTADO EN EL TUBO DESPUES DE HABERLE REDUCIDO EL DIAMETRO PASANDOLO POR UNA MATRIZ. LA PRESION DEL GAS O LIQUIDO DENTRO DEL REVESTIMIENTO EN USO ES MAYOR DE LO QUE EL REVESTIMIENTO PUEDE SOPORTAR POR SI SOLO, PERO LA LECHADA TRANSFIERE CARGA DE PRESION AL ARMAZON. EN MODIFICACIONES DE LA INVENCION, SE REEMPLAZA EL ACOPLE POR UN ACOPLE PECAT O POR ACOPLES DE PESTAÑAS UNIDOS A LOS TUBOS POR FUSION EXTREMA O POR ELECTROFUSION DIRECTAMENTE O POR MEDIO DE ACOPLES DE ELECTROFUSION. EL REVESTIMIENTO PUEDE COLOCARSE EN SU SITIO POR MEDIO DE ACCESORIOS DE ELECTROFUSION PARA PREVENIR EL CAMBIO DE DIMENSION POR EFECTO DE LA REVERSION.
