Filed: 2019-03-19
Abstract: To suppress swelling of lap at the start and end positions of overlay welding.SOLUTION: A seismic joint pipe has a configuration that, one end of a cylindrical straight part having a constant inner and outer diameter becomes a receiving port and the other end becomes an insertion port 2, a lock ring is loaded on the inner surface of the receiving port, and protrusions are formed on the outer peripheral surface of the insertion port. A seismic joint pipe structure is so configured that the protrusions are engaged with the lock ring so as to prevent the insertion port 2 of one pipe P from being detached from the receiving port of the other pipe. When forming the protrusions of the insertion port of the cast iron pipe, overlay welding is performed over the entire outer surface of the cast iron pipe, and the overlay welding is repeated a plurality of times to form the protrusions made of a plurality of weld beads. At that time, the wrap parts s1, s2, and s3 by overlay welding of each of beads a1, a2, and a3 are set to different positions in the outer peripheral direction of the cast iron pipe. Since the wrap parts of the weld beads are shifted, the swelling of the wrap parts by the overlay welding is suppressed, thus a good weld bead layer is obtained, resulting in easiness in finishing process on the swelling section.SELECTED DRAWING: Figure 1
