APPARATUS FOR DETECTING PIN-HOLE OF TUBE

摘要

PURPOSE: An apparatus for detecting a pin-hole of a tube is provided to improve workability by continuously performing a process for detecting the pin-hole. CONSTITUTION: An apparatus for detecting a pin-hole of a tube includes a pin-hole detecting unit(50) for detecting gas leakage in the pin-hole by passing the tube through an inner space isolated from an exterior. A detecting unit(65) receives a signal regarding the gas leakage in the tube from the pin-hole detecting unit(50). A marking unit(70) is provided to mark a position of a pin-hole position of the tube detected by the pin-hole detecting unit(50). An aluminum tube is extruded from an extruder(40). The pin-hole detecting unit(50) is positioned between guide rollers(60). The pin-hole detecting unit(50) includes a case having an internal cavity.
