Abstract
In a weldless joint 13, screwing a fastening member 13 into a joint body allows two pipes to move closer to each other in an axial direction without rotating. The two pipes can be thus connected without welded. Packings and disposed in the joint body prevent the leakage of gas through the contact surfaces of the pipes and, further, the leakage of gas from the inside of the joint body to the outside thereof. Accordingly, no packing or sealing element is needed on the periphery of the fastening member.
