  • Patent number: 10697568
    Abstract: A refrigerant pipe is provided to be capable of preventing a change in a length by which the refrigerant pipe is inserted after the refrigerant pipe is inserted. The refrigerant pipe includes a heat-exchanger-side pipe having a pipe component insertion flare formed at an end portion of the heat-exchanger-side pipe and at least one protrusion formed on an inner peripheral portion of the pipe component insertion flare, and a pipe component having a smaller outer diameter than an inner diameter of the pipe component insertion flare. A height of the at least one protrusion is greater than a dimension of a clearance defined on the basis of a difference between the inner diameter of the pipe component insertion flare and the outer diameter of the pipe component. The pipe component is inserted into the pipe component insertion flare, and the pipe component has a groove formed by the at least one protrusion.
