摘要： A method of manufacturing a double pipe includes a step of inserting a straight inner pipe into a straight outer pipe such that the inner pipe and the outer pipe are positioned at a predetermined relative position, a step of fixing a first end portion of the outer pipe to the inner pipe so as to form a first fixing portion, a step of bending the outer pipe and the inner pipe at the same time at a predetermined portion so as to form at least one bending portion after the fixing step of the first end portion, and a step of fixing a second end portion of the outer pipe to the inner pipe so as to form a second end portion after the bending.

摘要： A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be radially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.

摘要： A method of manufacturing a grooved pipe includes a pressing step and a longitudinally displacing step. The pressing step presses a grooving tool toward an outer surface of a wall of a pipe in a radially inward direction of the pipe at a location, which is separated by a predetermined distance from an end portion of the pipe. The longitudinally displacing is performed by longitudinally displacing at least one of the grooving tool and the pipe relatively in a longitudinal direction of the pipe while pressing the grooving tool toward the outer surface of the wall of the pipe to form a groove portion, which is recessed from the outer surface of the wall of the pipe. The method is suitably used for forming an inner pipe of a double-wall pipe.

摘要： A pipe joint has a joint main body, a union nut connected to the joint main body, and a lock ring. The lock ring has a tubular wall, and a first axial end and a second axial end of the tubular wall are deformable by inner walls of tapered hole portion of the joint main body and the union nut. The lock ring has a first tapered opening portion providing a first groove for receiving a first end of a first pipe member and a second tapered opening portion providing a second groove for receiving a second end of a second pipe member, in a radial inside of the tubular wall. A radial outer surface of the first tapered opening portion and a radial outer surface of the second tapered opening portion are tapered such that the first groove and the second groove are narrowed toward its ends, respectively.
