Abstract
Provided is a protective cap for a small-diameter thick-walled pipe that does not hinder during bending work or shape inspection of the pipe and it is thus possible to bend the pipe with the protective cap attached, thereby ensuring cleanliness inside the pipe. The protective cap for a small-diameter thick-walled pipe having a connection head at the end of the thick-walled pipe with the small diameter is composed of an inner cap having an integral structure of a plug to be tightly inserted into the connection head of the pipe and a gripping portion for attachment/detachment and an outer cap that includes a covering portion of the connection head and is fitted removably over the inner cap.
