[0026] It should be noted that the hydrogen pipeline is a pipeline system specially designed for transporting hydrogen. In order to improve the performance of the hydrogen pipeline and ensure the safety and reliability of the pipeline during the hydrogen transportation process, the hydrogen pipeline needs to be processed and heat-treated. First, turn the paddle and move the paddle to the first locking block so that the paddle is out of the locking state of the second locking block. Then flip the baffle 2 outward to make room for the hydrogen pipeline to be placed. Then, pass the hydrogen pipeline through the partition 4 and place it on the placement plate 6.
