How to add protective sleeves for large-diameter buried pipes
Thread Content
It is a buried pipe with a diameter of 1000 mm, located 500 m above the ground surface; it passes through roads within the factory area and requires protection using sleeves. Question: How to add a protective sleeve? How to choose the size? It is now determined that the pipeline is below the permafrost layer.
Why can’t it be deeper? A protective tube is simply a sleeve. What about the natural dispersion force of the backfill soil underground? This cannot be ignored.
I have to figure it out myself; please help. It’s best to include the calculation formula. Or providing the corresponding standards is also acceptable.
I don’t know what type of medium is used in the pipes mentioned by the poster; for most process media, there is a minimum required thickness of soil cover
Alkaline solution, PH=7-8
For alkaline solutions, it is recommended to use trenching; this will increase costs, but it is beneficial for future operation, management, and maintenance
What material is the pipe made of? If it is carbon steel, in accordance with the specifications, it can be coated with epoxy coal tar pitch coating, interpenetrating network anti-corrosion coating, or other anti-corrosion coatings.
