Hydrogen transportation pipe and hydrogen transportation pipeline

Abstract

Embodiments of the present application provide a hydrogen transportation pipe and a hydrogen transportation pipeline. A steel pipe body of the hydrogen transportation pipe has a pipe cavity with a round cross section; an inner wall of the pipe cavity of the steel pipe body is provided with a nano-composite coating used for preventing hydrogen atoms from diffusing into the steel pipe body; and an outer diameter of the steel pipe body is not more than 100 millimeters and a diameter of the pipe cavity of the steel pipe body is not more than 90 millimeters. According to the present application, a hydrogen embrittlement phenomenon can be prevented from occurring in the steel pipe body, and the transportation cost of hydrogen can be effectively reduced and the large-scale commercial application of the hydrogen energy can be further accelerated.
