In air heating applications, tubular heating elements are essential, efficiently converting electrical energy into thermal heat. These unpretentious but essential elements are made from two distinguished materials, each with its own distinct appeal—stainless steel (SS) and the esteemed Incoloy 800. These materials possess unique qualities that make them well-suited for various settings and specific uses, especially in air heating. Their perfection ensures that the heat they provide is not only practical but also a monument to the harmonic integration of science and material expertise.
Stainless Steel Tubular Heating Elements
SS tubular heating elements offer unmatched corrosion resistance, affordability, and temperature range. Advantages of SS heating elements include:
Corrosion Resistance
SS tubular heaters withstand oxidation and corrosion well, particularly in humid air. They are appropriate for modest air heating applications in mild operating environments.
Temperature Resistance
SS can endure moderate to high temperatures, however its mechanical qualities may decrease in air heating applications beyond 800°C.
Cost-Effectiveness
SS is cheaper than Incoloy 800, making it a good alternative for air heating applications without exceptional temperature resistance.
Incoloy 800 Tubular Heating Elements
Some features and attributes of Incoloy 800 include:
Superior High-Temperature Performance
Even at 1100°C, Incoloy 800 retains its mechanical qualities and corrosion resistance, making it excellent for air heating applications with intense heat.
Oxidation Resistance
For extended high-temperature air exposure, Incoloy 800 is better than stainless steel at oxidation and scaling resistance due to its high nickel and chromium content.
Longer Lifespan
In demanding applications, Incoloy 800 heating elements endure longer than SS ones because of their high-temperature stress performance.
Comparison of Air Heating Applications
Overall, air heating using SS or Incoloy 800 heating elements relies on application needs:
-
Stainless steel tubular elements are ideal for moderate-temperature air heating due to cost-efficiency and mild environmental conditions.
-
High-temperature air heating in challenging conditions benefits from Incoloy 800's exceptional characteristics and oxidation resistance, guaranteeing long-lasting performance even under stress.
