Stainless steel heat exchanger tube
What is stainless steel heat exchanger tube?
Tubes for heat exchangers are mounted inside the water heater storage by the inspection flange. The Stainless Steel Heat Exchanger Tubes are used in applications involving high heat and pressure. They avoid all types of welding connections to form a reverse or a bend in various directions.
The finned Stainless Heat Exchanger Tubes helps to transfer heat from the system by using its fins present on the surface of the pipe. The structure of the fins helps to make the whole process of heat transfer more efficient than the ordinary heat exchanger tubes. The SS Heat Exchanger Tubes are available in different sizes, dimensions and material grades, which are customizable as per the client's requirements.

Advantages of SS heat exchanger tubes
- Stainless steel is a durable and reliable material for heat exchangers, and thus, they can last for 50 years and above.
- They show good resistance to corrosion but the level would depend on the grade. Limestone and other material deposits can be avoided by using 316 stainless steel heat exchanger tubes.
- They have a simple design with different characteristics and cost which depend on the material grade. However, in general, they have a low purchase and maintenance cost.
- They have high strength and can withstand its properties in high temperature environments.
- 304 Stainless Steel Heat Exchanger Tubes has high heat transfer rate and can offer optimal performance throughout its service life.
- SS is compatible with different materials and surface treatments can be applied on the tubes to enhance its performance.

Advantages of stainless steel heat exchanger straight tube
The main benefit of SS Straight Tube Heat Exchanger is that they generate a very low pressure loss during the entire operation. Due to the straight design, they can be used in contaminated and viscous media without any issues. The straight ASTM A213 heat exchanger tubes are available in both upright and horizontal designs. They offer better overall performance and enhanced thermal conductivity at a reduced cost.
