A tubular assembly and method for its manufacture is disclosed wherein an internal device is positioned and sealed in-line within a metal tube that is formed by two sections which are spin, inertia, or forge welded together so that the flash produced by the weld flows into the interior tube where the device is placed and the flash seals the device outer wall peripherally to the tube inner wall to form a gas tight seal. In a preferred embodiment the internal device is a gas filter for hydrogen gas.
