The present invention relates to an internal printing apparatus for pipes.

In general, a pipe refers to a hollow thin tube, also called a tube or tube. The cross section of the pipe is usually circular, but there are other shapes. It is widely used in daily life such as water pipes and gas pipes and in various industrial facilities.

The pipe is mainly used for transporting a fluid (gas, liquid) or powder. It is also used for the protection of electric wires and cables when wiring in the ground or indoors. A passage of a fluid constituted by a pipe is referred to as a pipe route, and a pipe is reasonably installed in consideration of the flow rate, physical property value, frictional resistance, and the like of the fluid.

Such long pipes use pipe coupling to change the direction of the pipe in the middle of the pipe or to connect the pipe to the pipe when a pipe having a different thickness is used. In addition, since pipes are stronger against bending than rods of the same weight, they are widely used as constituent materials for machines and structures.

The pipe is divided into a metal tube and a non-metallic tube according to its material, and the metal tube includes a steel tube, a cast iron tube, a copper tube, a brass tube, an aluminum tube, a tube tube, and the like, and a non-metal tube includes a vinyl tube, reinforced concrete tube, Asbestos cement pipes, conduits, pipes, rubber pipes, wood pipes, and the like.
