    摘要: In order to maintain airtightness by a ferrule even by use of a general-purpose tool and to be capable of releasing airtightness by the ferrule if necessary, a pipe joint (Ja) includes a ferrule (33) receiving an axial pressing force from a fixing member (66a) screwed in a clamping direction thereby to airtightly seal a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P) when the fixing member (66a) is rotated in a clamping direction to be screwed in, a loosening male thread (68) formed on an outer periphery of the fixing member (66a) and threaded in a direction opposed to a direction in which the joint body (16) and the fixing member (66a) are threaded, a loosening tool (130) screwable into the loosening male thread (68), and a pressure receiving portion (39) abutting against the loosening tool (130) thereby to prevent further screw-in when the loosening tool (130) is screwed into the loosening male thread (68) and rotated in the direction opposed to the clamping direction of the fixing member (66a).

    摘要: In order to improve the reliability of sealing performance, a pipe joint (Ja) includes a cylindrical clamping member (32) screwed into a joint body (16), a ferrule (33) receiving an axial pressing force from the clamping member (32) screwed in a clamping direction, thereby airtightly sealing a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P), a cylindrical fixing member (66a) constructing the clamping member (32) and abutting against the ferrule (33) to apply a pressing force to the ferrule (33), a clamping nut (36) constructing the clamping member (32) and having an outer periphery formed with a non-circular fitting portion (48) and receiving a screw-in force in the clamping direction, thereby imparting to the fixing member (66a) a pressing force to the ferrule (33) side, and a locking unit (41) preventing the fixing member (66a) from displacement in a direction such that the ferrule (33) is released from the pressing force applied by the fixing member (66a).
