The invention discloses a seamless steel pipe cap with a label. The seamless steel pipe cap comprises a steel pipe cap body and is characterized in that a bulge is arranged in the center of the steel pipe cap body; the bulge is connected with one end of a thread; the label is hung at the other end of the thread; the gravity center of the label is close to the lower part of the label and in the direction of the thread; the label can do swing motion through the thread and the bulge. According to the seamless steel pipe cap, the gravity center of the label is close to the lower part of the label and in the direction of the thread, and the label can do swing motion through the thread and the bulge, so that the label keeps facing down at all time. Therefore, no matter how the position of a seamless steel pipe is changed, the information of the seamless steel pipe can be read conveniently.
