PROBLEM TO BE SOLVED: To provide a pipe cap and a piping that while being attached to an end of a pipe, can prevent connection of a pipe connection member such as an elbow for example, thereto.SOLUTION: A pipe cap and a piping constitute integrally: a pipe cap 10 attachable to and detachable from a pipe end 1a of a pipe 1 allowing a pipe connection member to be externally fitted to an outer peripheral surface thereof; an insertion portion 12 formed like an approximate cylinder shape corresponding to an inner peripheral surface of the pipe end 1a in the piping 1; and a cap main body 11 that contacts with an end face of the pipe end 1a to close the pipe end 1a. In at least a part in a peripheral direction of the cap main body 11 is arranged the pipe cap 10 that protrudes in an outside diameter direction from an outer peripheral surface 1b of the piping 1 and has a length H from center of the cap main body at a protruding end 13a longer than an inside radius of the externally fitted portion in the pipe connection member. |
