In heating systems, various types of pipelines are used. Basically, pipes are made of steel, non -ferrous metals (copper, aluminum) and polymers.
In apartments, steel pipes are most common, due to their relatively low cost. The main disadvantage is very low corrosion resistance. There are several ways to protect against the formation of corrosion, one of them is zinc. But in the galvanizing system it is contraindicated to use antifreeze. Among other things, another drawback is a complex and expensive installation.
