I would like to bury the heating insulation pipe directly underground. How should I do that? ?
Then dig a trench, lay 200 mm of sand at the bottom of the trench and 500 mm at the top, and compact it in layers
Isn’t it enough to ensure good insulation?
Is there such a convenient standard? ? ? ?
To change the design, switch to buried pipes. Buried pipes are different from above-ground insulated pipes, so they need to be purchased anew. At the same time, the feasibility of buried pipe construction must be considered; different construction methods such as jacking, pulling, and direct burial require different designs and pipe types.
By the way, geophysical surveys are also necessary for pipeline routing; it’s important to fully understand the conditions underground, otherwise problems are likely to arise.
What is the construction method for directly buried F? ?
The trench is a good option; the pipes should be insulated
