<p><P>PROBLEM TO BE SOLVED: To provide a pipe joint for piping capable of suppressing leakage of refrigerant to a small extent. <P>SOLUTION: A comparatively soft aluminum sealant 50 is nipped between a male side pipe joint 100 and a female side pipe joint 200 to tighten by a bolt 80. Since an annular recessed part 33 and an annular projecting part 42 are provided in a collar part 31 of a pipe 30 of the male side pipe joint 100 and at a tip of a pipe 40 of the female side pipe joint 200, respectively, the annular projecting part 42 bites the sealant 50, and the sealant 50 sticks out from the annular recessed part 33 when fitting and tightening the male side and female side pipe joints to achieve high performance sealing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
