Stainless steel heating tube

Stainless steel heating tubes are electric heating elements with a stainless steel outer shell, internally filled with magnesium oxide sand and encapsulated with spiral electric heating alloy wires (nickel-chromium/iron-chromium alloy), achieving efficient heating through a forced circulation system. Their core features include: Efficient Heating: Heating fluids via forced convection, with a maximum operating temperature of up to 850°C. Safety and Controllability: Supports full automated control and can be connected to computers to adjust parameters such as temperature and pressure. Corrosion Resistance: 316L material is suitable for weak acid-base environments, while 321 material enhances high-temperature corrosion resistance.  Application Scenarios Primarily used for fluid heating in explosion-proof or general environments, such as mold heating, chemical equipment, food processing, and other industrial fields, as well as civilian applications like air curtains and ovens.  It is important to avoid placing flammable materials near high temperatures for extended periods and to regularly descale when heating water to extend service life.
