Outdoor weather-resistant anti-corrosive pipeline

Abstract

The invention discloses an outdoor weather-resistant anti-corrosive pipeline and belongs to the field of anti-corrosive pipelines. The outdoor weather-resistant anti-corrosive pipeline comprises two pipe bodies. The sides, close to each other, of the two pipe bodies are both fixedly connected with connecting flanges. The two connecting flanges are fixedly connected through screws. The tops and thebottoms of the two connecting flanges are sleeved with arc-shaped clamp rings. The surfaces of the arc-shaped clamp rings are provided with external threads. The surfaces of the two pipe bodies are both sleeved with thread sleeves. The thread sleeves are in threaded connection with the arc-shaped clamp rings through the external threads. The sides, far away from each other, of the two thread sleeves are both rotatably connected with rotary pipes located on the surfaces of the pipe bodies. Through the outdoor weather-resistant anti-corrosive pipeline, the problems that the joints of most of pipelines are exposed outside, are likely to get rusty and get leaked through long-time washing of rainwater and other things, the service life of the pipelines is shortened and the pipelines cannot adapt to the weather like the winter and the summer with too large external temperature difference are solved.

Description

technical field [0001] The invention relates to the field of anti-corrosion pipelines, in particular to a weather-resistant anti-corrosion pipeline for outdoor use. Background technique [0002] Anti-corrosion pipelines are pipelines that adopt pipeline anti-corrosion measures. Pipeline anti-corrosion measures refer to measures to slow down or prevent pipelines from being corroded and deteriorated under the chemical and electrochemical effects of internal and external media or microbial metabolic activities. [0003] Existing anti-corrosion pipelines generally use an anti-corrosion layer on the outer wall of the pipeline to realize the anti-corrosion of the pipeline. At present, there are many kinds of pipeline connections used outdoors, such as screw connection, flange connection, groove connection, etc., but using this Most of the connections of these pipes are directly exposed to the outside; after a long time of rainwater, etc., it is easy to cause rust on the connection...
