EFECTO DE LA ALTURA DEL MANGUITO EN UNIONES SOLDADAS EN CAÑERÍAS DE COBRE BUSHING HEIGHT EFFECT IN SOLDERED COPPER PIPE JOINTS
Se perforó un tubo de cobre de 28,6 mm de diámetro, por el proceso de taladrado por fluencia térmica (TFT). Se prepararon manguitos de diferentes alturas, haciendo un preperforado con brocas convencionales HSS de diferentes diámetros. Se seleccionaron manguitos de dos alturas diferentes. Se determin...

Se prepararon manguitos de diferentes alturas, haciendo un preperforado con brocas convencionales HSS de diferentes diámetros. Se seleccionaron manguitos de dos alturas diferentes. Se determinó la circularidad de la perforación. Se soldó un tubo cobre de ø 12,7 mm en forma perpendicular a un tubo de cobre de ø 28,6 mm y se determinó la resistencia a la tracción de la unión soldada, para lo cual se diseñó un dispositivo mecánico que fue adaptado en la máquina universal de ensayos. Se hicieron ensayos de microdureza y metalografía de la unión. Se concluyó que el manguito de menor altura es suficiente para que la unión alcance la máxima resistencia.<br<Copper tubes were drilled with thermal flow drilling. Conventional HSS drills diameters were used to make pre drilling holes. Different height bushings were made. Two of the bushing heights were selected. The bushing circularity was measured. A ø 12,7 mm tube was welded perpendicularly on a ø 28,6 mm tube. A especial support device was designed and it was adapted to the Universal Test Machine, to determine the tensile stress of the brazing joint. The micro hardness and metallographic test were made in the brazing zone. As a conclusion the lower height bushing is enough to reach the maximum resistance. | ||

Conventional HSS drills diameters were used to make pre drilling holes. Different height bushings were made. Two of the bushing heights were selected. The bushing circularity was measured. A ø 12,7 mm tube was welded perpendicularly on a ø 28,6 mm tube.

EFECTO DE LA ALTURA DEL MANGUITO EN UNIONES SOLDADAS EN CAÑERÍAS DE COBRE BUSHING HEIGHT EFFECT IN SOLDERED COPPER PIPE JOINTS |
abstract |
Se perforó un tubo de cobre de 28,6 mm de diámetro, por el proceso de taladrado por fluencia térmica (TFT). Se prepararon manguitos de diferentes alturas, haciendo un preperforado con brocas convencionales HSS de diferentes diámetros. Se seleccionaron manguitos de dos alturas diferentes. Se determinó la circularidad de la perforación. Se soldó un tubo cobre de ø 12,7 mm en forma perpendicular a un tubo de cobre de ø 28,6 mm y se determinó la resistencia a la tracción de la unión soldada, para lo cual se diseñó un dispositivo mecánico que fue adaptado en la máquina universal de ensayos. Se hicieron ensayos de microdureza y metalografía de la unión. Se concluyó que el manguito de menor altura es suficiente para que la unión alcance la máxima resistencia.<br<Copper tubes were drilled with thermal flow drilling. Conventional HSS drills diameters were used to make pre drilling holes. Different height bushings were made. Two of the bushing heights were selected. The bushing circularity was measured. A ø 12,7 mm tube was welded perpendicularly on a ø 28,6 mm tube. A especial support device was designed and it was adapted to the Universal Test Machine, to determine the tensile stress of the brazing joint. The micro hardness and metallographic test were made in the brazing zone. As a conclusion the lower height bushing is enough to reach the maximum resistance. |
