Improved steel lining anti-corrosion pipeline

Abstract

The invention relates to an improved steel lining anti-corrosion pipeline. The improved steel lining anti-corrosion pipeline comprises a pipe body internally provided with an anti-corrosion channel. The pipe body is internally provided with compensation spaces communicating with the anti-corrosion channel. The compensation spaces are arranged at intervals. A reserved channel is arranged outside the pipe body. An alarm line is arranged in the reserved channel. Alarm devices are arranged on the alarm line at intervals. The alarm line is provided with alarm triggering lines extending into the compensation spaces. The spacing distance between the alarm devices is equal to the spacing distance between the compensation spaces. The pipe body is further provided with pre-repairing cavities with the spacing distance the same as the spacing distance between the compensation spaces. The improved steel lining anti-corrosion pipeline has the beneficial effects that the problem about pressure expansion of anti-corrosion materials forming the anti-corrosion channel can be effectively relieved through the compensation spaces, the alarm triggering lines in the compensation spaces can conduct the test on the pressure in the compensation spaces and the anti-corrosion channel, and after the pressure value breaks through one section, the alarm line and the alarm devices can be triggered to give an alarm, and a worker can know the anti-corrosion situation in the anti-corrosion channel in time and conduct timely checking and repairing.

Description

technical field [0001] The invention relates to the field of anticorrosion pipelines, in particular to an improved steel-lined anticorrosion pipeline. Background technique [0002] As people pay more and more attention to the internal and external corrosion of pipelines, various organic and inorganic high-efficiency anti-corrosion coatings are more and more widely used in pipeline anti-corrosion construction, various anti-corrosion technologies are also becoming more and more perfect, and significant anti-corrosion has been achieved. Effect, especially the external anti-corrosion construction of pipelines, such as coal tar pitch paint, epoxy paint, adhesive tape, yellow jacket, etc. However, the anti-corrosion construction of the inner wall of the pipeline has not been completely solved due to the anti-corrosion problem of the inner surface of the pipeline near the weld, that is, the problem of internal jointing, which seriously hinders the application of various high-effici...
