Abstract

LA INVENCION SUMINISTRA UNA JUNTA (80) PARA DOS TUBOS DE ACERO (50, 52) CADA UNO DE LOS CUALES COMPRENDE UN REVESTIMIENTO INTERNO (54, 56) DE POLIMETILENO. LA INVENCION TAMBIEN SUMINISTRA UN DISPOSITIVO DE ACOPLAMIENTO POR ELECTROFUSION PARA UNIR LOS REVESTIMIENTOS; UN METODO PARA FABRICAR EL DISPOSITIVO DE ACOPLAMIENTO Y UN METODO PARA HACER LA JUNTA (80). LA JUNTA (80) CONSTA DE UN DISPOSITIVO DE ACOPLAMIENTO DE ELECTROFUSION QUE TIENE DOS SUPERFICIES EXTREMAS EXTERIORES FRUSTOCONICAS QUE ENCAJAN EN SUPERFICIES SIMILARES SOBRE LOS INTERIORES DE LA PARTES EXTREMAS DE LOS REVESTIMIENTOS. LAS UNIONES SOLDADAS POR FUSION SE FORMAN EN LAS INTERCONEXIONES ENTRE LAS SUPERFICIES FRUSTOCONICAS. UN CUERPO DE MATERIAL AISLANTE (66) ES RECIBIDO EN UN HUECO CENTRAL EN EL DISPOSITIVO DE ACOPLAMIENTO Y PROTEGE EL DISPOSITIVO DE ACOPLAMIENTO DE LAS ALTAS TEMPERATURAS DE LA SOLDADURA DE UNION (70) ENTRE LOS TUBOS DE ACERO (50, 52). LAS SUPERFICIES FRUSTOCONICAS HACEN UN ANGULO DE 10 (GRADOS) O INFERIOR CON RESPECTO AL EJE LONGITUDINAL DEL DISPOSITIVO DE ACOPLAMIENTO. UN CUERPO DE SOPORTE (14) DE METAL O DE MATERIAL DE PLASTICO SINTETICO CONTENIDO POR EL DISPOSITIVO DE ACOPLAMIENTO POR ELECTROFUSION ASEGURA QUE EL DISPOSITIVO DE ACOPLAMIENTO ESTE ADECUADAMENTE SOPORTADO DURANTE LA ELECTROFUSION.
