Abstract
Un método perfeccionado de reparar una tubería situada bajo el agua de la que se ha eliminado un tramo defectuoso o deteriorado de tubo para formar dos extremos de tubo expuestos, separados entre sí longitudinalmente, cuyo método incluye las operaciones de: (a) soldar a tope a un extremo de tubo expuesto una parte extrema tubular de un primer miembro hueco, de extremos abiertos que tiene una superficie de acoplamiento parcialmente esférica, interior o exterior; (b) soldar a tope un manguito al otro extremo expuesto del tubo; (c) montar en el manguito una parte extrema tubular de un segundo miembro hueco de extremos abiertos que tiene una superficie de acoplamiento parcialmente esférica, complementaria de la del primer miembro de extremos abiertos; y (d) soldar con cordón el manguito a la parte extrema tubular del segundo miembro de extremos abiertos y las superficies de acoplamiento de los miembros de extremos abiertos, entre sí; en cuyo método, el manguito y las partes tubulares de los miembros de extremos abiertos tienen diámetros interiores y espesores de pared radiales tales que resulta posible realizar las soldaduras a tope independientemente de la parte del margen de diámetros exteriores especificados para la tubería, en que se encuentran los diámetros exteriores reales de la tubería.
