APPARATUS FOR INSPECTING LEAKAGE

摘要

Disclosed is a leakage inspecting device. According to an embodiment of the present invention, the leakage inspecting device is capable of inspecting a leakage of a primary barrier of a liquefied natural gas hold and includes a probe absorbing gas for inspection while moving along a welding line extended in an X-axis direction, which is vertical to a colocation of the primary barrier; a trolley moving the probe in the X-axis direction; an Z-axis transfer part installed in the trolley and moving the probe in a Z-axis direction, which is vertical to a plane part of the primary barrier; a T-axis rotating part rotating the probe around a T-axis, which is vertical to an XZ plane formed of X and Z axes; and a gap maintaining part maintaining a constant gap between an inlet of the probe and the welding line.
