<P>PROBLEM TO BE SOLVED: To provide a pipe joint, and freezing equipment using the pipe joint capable of securing sealing performance of a junction while improving workability in connection of a pipe arrangement by preventing misplacement of a sleeve. <P>SOLUTION: The sleeve 15 is integrally formed with respect to a nut 14 before junction of the pipe arrangement, and it is cut off from the nut 14 and separated by screwing of the nut 14 into a joint body. Since a recessed part 15g is formed on an inner circumference face 15d of the sleeve 15, when the sleeve 15 bites into the pipe arrangement 12, by thrust from an inner side face 14c of the nut 14, deformation of an abutting face 15c is induced such that a contact area A1 of an abutting part between the abutting face 15c and a guide face 13d is enlarged. <P>COPYRIGHT: (C)2007,JPO&INPIT |
