Flexible composite pipe product and marking method

The invention relates to a flexible composite pipe product with a transparent outer layer and an inkjet printing marking method. The flexible composite pipe comprises an outer layer pipe and an inner pipe bonded with the outer layer pipe, wherein the outer layer pipe is transparent; and a pipe mark is arranged outside the inner pipe. The marking method for the flexible composite pipe comprises the following steps of: extruding the transparent outer layer pipe which is bonded with the inner pipe by using an outer layer pipe extruder; and performing inkjet printing on the inner pipe by using an inkjet marker which is positioned between the output part of the inner pipe and the outer layer pipe extruder. Compared with the conventional pipes, the flexible composite pipe product comprises the pipe mark which is printed in the pipe, so the protection functions of preventing abrasion and the like can be realized. A production process can be implemented only by regulating the positions of the devices without arrangin
