On the other hand, the male thread shape 423 of the seventh connecting portion 421 and the female thread shape 445 of the eighth connecting portion 441 can be connected and fixed to each other. The male screw shape 464 of the tenth connection portion 462 and the female screw shape 445 of the other end of the eighth connection portion 441 can be fitted and connected to each other. On the other hand, the flange can be formed as a polygonal shape so that the operator can easily connect the male screw to the female screw.

As a result, it is possible to prevent warping of the connecting portions of the first PE pipe 10 and the second PE pipe 30. Further, watertightness and airtightness can be enhanced.

17 (a) and 17 (b) are cross-sectional views showing a section of the PE pipe connecting socket 400 of FIG. 17 (a) and 17 (b), the seventh connecting hole 420, the third rubber packing 430, the eighth connecting hole 440, the fourth rubber The packing 450, and the tenth connection port 460 can be confirmed.

17 (a) is an upper section of a vertically cut section of the PE pipe connection socket 400 of FIG. 16, and FIG. 17 (b) is a cross section of a vertically cut section of the PE pipe connection socket 400 of FIG. 17 (a) and 17 (b) can be hollow.

Meanwhile, the PE pipe connecting socket 200 to which the seventh connecting pipe 420, the third rubber packing 430, the eighth connecting pipe 440, the fourth rubber packing 450, and the tenth connecting pipe 460 are coupled 18.

FIG. 18 is a perspective view showing a PE pipe connecting socket combining the configurations of FIG. 16; 18, the PE pipe connecting socket 400 may connect the first PE pipe 10 and the second PE pipe 30.
