Why can’t oil and gas pipelines pass under drainage bridges and culverts?
Thread Content
When I was abroad, I saw that foreigners used a pipeline running across the road, employing culverts from seasonal rivers; however, this is not allowed in my country. I don’t know why it’s prohibited
Can you confirm whether the pipeline through which the foreigner was found crossing a road drainage bridge abroad is an oil and gas pipeline?
Sure, because they plan to lay another one parallel to this one, and there are still some pipes that protrude above the surface
Who can guarantee that pipelines won’t break and leak? It seems that last year there was a leak in a pipeline in Huangdao into a drainage ditch, which led to an accident; one could look into that incident further.
In addition to the aforementioned leakage issues, there is another reason: generally, culverts are designed for drainage purposes, and their size is determined based on parameters related to rainwater or floods. If pipes are installed inside a culvert, this theoretically reduces the cross-sectional area of the culvert’s opening, resulting in an increased flow rate of rainwater. This can cause damage to the roadbed and the culvert itself, and it is also likely to damage the pipes installed within the culvert.
