Brass tubes, as distinct from copper ones, have better strength and corrosion-resistant characteristics due to the presence of zinc in their composition.
High mechanical stability occurs in air, in water, in the sea, as well as in carbonic, organic acids or solutions.
Bimetallic ribbed tubes with a supporting brass tube are used in inter-cycle and end air coolers (ВОТ-229, ВОТ-380, ВОТ-2000, etc.) of K-250.. K-7000 compressor units, heating and cooling systems, etc.
