Abstract
The present invention relates to a flexible wire (100), which is inserted in a pipe and rotated in a high speed to remove scale produced in a pipe by striking. A flexible wire (100) for removing pipe scales comprising: a main wire (110) having plural wires twisted in a spiral direction as one body, wherein the main wire (110) has an overall straight shape; and an auxiliary wire (120) having plural wires twisted in a spiral direction as one body, of which a diameter is substantially smaller than a diameter of the main wire (110), wherein the auxiliary wire (120) is secured to the main wire (110) and has an overall repeated S-shape.
Claims5
A flexible wire for removing pipe scales comprising:
- a main wire having plural wires twisted in a spiral direction as one body, wherein the main wire has an overall straight shape, the main wire forming a central axis of rotation;
- and
- an auxiliary wire having plural wires twisted in a spiral direction as one body, of which a diameter is substantially smaller than a diameter of the main wire,
- wherein the auxiliary wire is secured to the main wire and has an overall repeated S-shape curving along a plane parallel to a longitudinal axial plane of the main wire.
