As shown in fig. 1 to 4, the utility model provides a hydrofluoric acid resistant cylinder, which comprises a cylinder body 10, wherein flanges 20 are arranged at two ends of the cylinder body 10. The flange 20 is detachably connected with the cylinder 10, and a sealing groove 21 extending inwards is formed in the inner end surface of the flange 20. A sealing ring 1120 is fixedly arranged on the corresponding end surface of the cylinder body 10, and the sealing ring 1120 is matched with the sealing groove 21.

In the present utility model, the cylinder 10 is detachably connected to the flange 20. During transportation, a worker can detach the flange 20 from the cylinder 10 and then stack the cylinder 10 together, and the flange 20 is stacked together, thereby reducing the occupied space.
