Abstract

EN EL PROCESO DE ABOCINAMIENTO DE UN CARTUCHO DE ESTAS CARACTERISTICAS (6) SURGE, DEBIDO A LA ESTABILIDAD RECUPERABLE DE LOS MATERIALES QUE LO CONFORMAN, UNA RENDIJA DE 5 A 10(MU)M APROXIMADAMENTE ENTRE LA TUBERIA (2) Y EL CARTUCHO (6). PARA EVITAR UNA VIA DE AGUA A TRAVES DE ESTA RENDIJA SE PREVEE QUE EL CARTUCHO (6) SOSTENGA UN ELEMENTO DE CONSTRUCCION EN SU PARTE PERIFERICA DE ALEACION DE MEMORIA FORMAL, DENTRO DE LA PARTE DEL EXTREMO (7, 8), QUE CUENTA CON UNA JUNTA ENTRE EL CARTUCHO Y LA TUBERIA (2) PARA CONSEGUIR LA TEMPERATURA PRETENDIDA. EL CARTUCHO SE EMPLEA PRIMORDIALMENTE EN LA REPARACION DE TUBERIAS TERMICAS.
