What Is Stainless Steel Heat Exchanger Tube?


A stainless steel heat exchanger tube is a module designed to transfer heat amongst two or more sets of fluids. The versatile module is employed in heating and cooling processes. The high-strength tubes are designed with a superior composition of chromium, giving these modules enhanced resistance to corrosive and oxidative media. The shell and tube of the heat exchanger module is a common feature in oil refineries and oil and gas systems where the modules are susceptible to higher temperatures and pressures.


What Are Shell And Tube Heat Exchangers Used For?


Shell and tube heat exchangers are high-strength modules employed in a range of temperature systems. These modules are employed in cooling or heating different volumes of process fluids and gases in different systems. These versatile modules are a feature in chemical processing systems, oil, and gas production systems. They also play a pivotal role in condensing gases, evaporating liquids, and cooling fluids at low temperatures across the systems.

What Are The Advantages Of Stainless Steel Fin Tube Heat Exchanger?
Stainless steel fin tube heat exchangers are cladded grades of modules having brazed fins. The advantage of these flanges is that these fins offer superior contact with the fluid present outside. The simple but effective process helps in fastening the heat exchanger between the liquid in the interior and the exterior parts of the tube. The rate of heat exchange substantially increases when using these modules compared to standard tubes.


How To Find If Stainless Steel Heat Exchanger Is Leaking?


In several instances, stainless steel heat exchangers fail due to small cracks or dislodged gaskets within the piping system. To identify a potential leak in heat exchangers, follow these simple steps.

  • Drain and isolate the pipe allowing for proper examination of the heat exchanger to take place.
  • A water test can be performed on the heat exchanger to check if there is no leakage in the system. The module can be seen whether there is a wet or dry side.
  • Disassemble the tubing as per the manufacturer’s guidelines and observe the plate carefully.

Can A Stainless Steel Heat Exchanger Tubing Be Welded?
Heat exchanger tubing is employed in high pressure and temperature applications. A welded tube is not preferred in heat exchanger tubing as it may be susceptible to breakage due to welds or seams present in the welded configuration. This tubing can be used in the welded configuration when the pressure embedded in the tube is ≤ 6.4 MPa.
