Abstract

An underwater pipe assembly includes first and second pipes each of which has opposite inner and outer circumferential surfaces and an annular end face. An inner coil surrounds the inner circumferential surfaces of the first and second pipes at a junction therebetween. An annular inner cover layer covers the inner coil. An outer coil is sleeved on the outer circumferential surfaces of the first and second pipes at a position corresponding to the inner coil. An annular outer cover layer covers the outer coil. When the inner and outer coils are energized, the end faces of the first and second pipes are melted to fuse together the pipes, and the inner and outer cover layers are melted to radially fuse with the pipes.
