At the time of the above-mentioned re-inspection, the gas container, which is the object to be inspected, was manually carried to each work position to perform the work in order, but since the gas container is heavy and has a shape difficult to carry, It required a lot of labor and the work efficiency was poor. In order to solve this, it is also carried out by suspending the gas container on a hanger and carrying it by a chain conveyor, but there is no system for carrying out a series of work continuously while carrying it by the conveyor, and still It was inefficient. In particular, the shot blasting process is performed in a separately provided shot blasting chamber with the gas container lying down, so it takes labor and time to put in and take out the gas container.

The gas container suspended on the conveyer 13 is sent to the shot blasting device 16 to be shot blasted. The shot blasting treatment is a treatment of blowing a shot by centrifugal force to remove rust and old paint on the outer surface of the gas container. The posture is regulated by a regulation guide while the gas container is suspended on the hanger of the conveyor 13. Processing is performed with a gun (shot discharge nozzle) whose position is fixed while rotating the gas container around a vertical axis.
During this time, the movement of the conveyor is stopped. The processing time per container is usually 1 minute or less.
