Abstract:
To provide a resin-made pipe joint which can prevent an adverse effect exerted to the circulation of fluid resulting from tapered internal flow passages whose flow passage cross section areas are gradually increased as processing toward welded end parts.SOLUTION: Resin-made pipe joints 1, 11 and 21 have tubular joint main body parts 2, 12 and 22 having internal flow passages P for making fluids circulate, and two or more welded end parts 3a to 3c, 13a, 13b, 23a and 23b which are arranged at two or mor opening portions of the internal flow passages P, made to abut on end parts of resin-made tube members for piping, or end parts of the other resin-made pipe joints, and welded thereto. Flow passage cross section areas of the internal flow passages P of the joint main body parts 2, 12 and 22 become constant at portions at least whose outside diameters adjoining the welded end parts 3a to 3c, 13a, 13b, 23a and 23b are straight.SELECTED DRAWING: Figure 1
