Application
Stainless steel tubes are widely used in heat exchangers due to their excellent thermal conductivity, corrosion resistance, and durability. Heat exchangers are critical components in industries such as chemical processing, oil and gas, power generation, HVAC, and refrigeration. Stainless steel tubes are particularly favored for their ability to withstand high temperatures, pressure, and corrosive environments.
