What conditions must existing pipelines meet in order to be reused?
Thread Content
Sometimes, some devices have unused pipelines, which is undoubtedly a waste. It is meaningful to be able to reuse them to save resources and make full use of the pipeline installation space. However, existing pipelines are not new pipelines after all; certain requirements must be met in order to reuse them. So what are these requirements? What are the relevant specifications? I hope the experienced teachers can offer some guidance~~
When reusing existing materials, at least one should check whether the intended use, materials, amount of wall thickness reduction, and pressure-bearing capacity meet the design requirements Just like the regular water pipes used in normal applications, the pipes purchased are those severely corroded; after removing the rust, as long as their wall thickness still meets the technical requirements, they can be used ； Don’t use hazardous materials ； There was once a project in South Korea where the pipes brought in were severely rusted inside; it was necessary to use wire brushes to scrub the entire interior in order to remove the rust.
