What material of buried pipeline needs to be treated with rust prevention? What kind of material needs to be treated with antiseptic, what kind of material is it made or not?
Cast iron pipes and steel pipes need to be protected from corrosion. The rest are basically not needed, such as concrete pipes, plastic pipes, glass pipes, etc.;
But such as corrosive or too humid environment, such as galvanized steel pipe also need anti-corrosion; there are electrochemical corrosion conditions, such as beaches, concrete, not repair steel pipe also have anti-corrosion measures; and so on.
