The Use of Duplex Stainless Steel Tubing in Heat Exchanger Service
Duplex stainless steel tubing is characterised by high chromium (19–28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as “super duplex” due to its higher resistance to corrosion.To improve the performance of your industrial process heat exchanger, we always use duplex stainless steel tubing . Heat exchangers are key components for many industries, particularly in chemical and oil and gas plants where they play a vital role in process control. Industry professionals — from design engineers and fabricators to the in-plant operators who work with the equipment daily — seek new ways to improve heat transfer performance and extend the life of these units in corrosive environments. Many times, improvements are closely related to the tubing specified for use in their heat exchangers. To improve the performance of ...
