Heat-exchanger tubes are used for shell & tube heat exchangers, plate & frame heat exchangers, cooling towers, air coolers, and others.
The main industries for heat-exchangers involve several critical applications that require high corrosion resistance materials and adherence to the highest quality standards.
Some of these applications include condensers, coolers, evaporators, heaters in refinery, petrochemical, chemical, oil/gas, organic and inorganic acids, hydrometallurgy, power generation, and desalination.
