Figures 1 to 3 show an example of the embodiment of the present invention in which a groove for storing the packing is formed in the flange member. Figure 1 is a cross-sectional view of the flange member,
The figure is a cross-sectional view of the end of a cast iron straight pipe, Figure 3 is a cross-sectional view of the flange member of Figure 1 screwed onto the straight pipe of Figure 2, and Figures 4 to 6 show the formation of the packing storage space. This shows an example in which a flange member and a straight pipe are both formed. Fig. 4 is a sectional view of the flange member, Fig. 5 is a sectional view of the end of the cast iron straight pipe, and Fig. 6 is the straight pipe of Fig. 5. 4 is a cross-sectional view of the flange member shown in FIG. 4 screwed together. Note that all the cross-sectional views in the drawings are longitudinal cross-sectional views. Fig. 7 shows an embodiment of the present invention in which a sealant is applied to the threaded part in Fig. 3, and Fig. 8 shows an embodiment of the invention in which a sealant is applied to the threaded part in Fig. 6. An example is shown in FIG. 9, which is a chart showing the amount of deflection of the central portion and the change in internal water pressure when a bending moment is applied to the flange portion of the present invention. 1: Flange member, 6: Tapered male thread, 2:
Tapered female thread, 7: Unthreaded part (straight pipe side), 3
