| description | The utility model relates to a circular-cutting capillary copper tube. The circular-cutting capillary copper tube is characterized in that tube ports at the two ends are flattened and sealed; and the rear end is flattened, and then a circular-cutting technology is utilized for cutting the outer tube wall to form a circular-cutting port, wherein the depth of the circular-cutting port is 1/4-1/2 of the tube wall, and the length of the circular-cutting port is more than 3/4 of the circumference of the tube. In the circular-cutting capillary copper tube, the tube ports at the two ends are flattened and sealed, the oxidation of the inner wall of the copper tube is effectively avoided, the phenomenon that the cleanness is over the standard is reduced, especially for tubes needing to be conveyed by a long distance, the two ends of the tube are provided with circular-cutting ports, the flattened tube ports can be easily broken off in the use process of the circular-cutting capillary copper tube, the tube wall is not |
