Abstract

PURPOSE: To constitute a joint for thin-walled pipes more easily than by conventional methods by providing an expanded part to the end of the joint body, fitting a packing in its inside annular groove, supporting the expanded part by jigs of a given shape and letting said end part be bitten under pressure into the outside surface of the pipe to be connected.
CONSTITUTION: An expanded part 3 is provided at the center of the pipe-inserting part 2 of the end of a joint body 1 by leaving a straight pipe part 5, and a packing 7 is fitted in the annular groove 4 of its inside surface. The expanded part 3 is then supported by the jigs 8, 8' formed with tapered faces 8a, 8a' on its inside, and the leading end of the straight pipe part 5 is pressed in the axial direction so that the edge 6 on the inside-diameter side is bitten into the outside surface of the pipe 10 to be connected. In this way, the straight pipe part 5 of the joint end deforms into arc form and is prevented from being disengaged from the joint body 1 of the bitten pipe 10. This method may be executed more easily than conventional methods and is suited for connection of thin-walled metal pipes.
