Stainless steel heating pipe can be installed in the pipeline or other static hair, flowing air heating applications; in metal stamping, machinery manufacturing, automotive, textile, food, household appliances and other industries, particularly in the air curtain air conditioner industry, heating pipes as hot stamping industry elements are widely used, a common shape structure: I type (straight tube), U-type, W-type (M type), O-type (ring) and the like. Stainless steel heating tube is a metal tube for the shell, along the tube axis within the central uniform spiral heating alloy wire (nickel-chromium, iron-chromium alloy) compacted fill their voids with good thermal insulation properties of magnesium oxide, silica gel or both ends of the nozzle ceramic sealing, high degree of mechanization electric stainless steel tube, in accordance with the requirements of customers in various shapes bent, lightweight, easy disassembly. Features: Electric heating tube structure is simple, less material, cheap cost, and long service life, heat conversion rate, while the energy saving. In the high temperature stainless steel seamless pipe evenly distributed within the high temperature heating wire, in densely populated part of the gap thermal conductivity and good insulating properties of crystalline magnesium oxide powder were well insulated, so when energized surface heat insulation is not charged, the use of safety . This structure is not only advanced, high thermal efficiency, and even heating, high temperature resistance wire when there is a current, the heat generated by the crystalline magnesium oxide powder to the metal tube surface diffusion, and then passed to the heating element or the air is going to achieve heating purposes. This metal tubular heating elements can heat the air, metal molds and various liquids. Stainless steel heating pipe material selection factors affect the quality of stainless steel heating pipe, the quality of materials account for a very important reason. Reasonable choice of electric heating raw materials, is to ensure the quality of the premise of heating pipe. Material choices include the following for reference: 1, selection principles pipe: temperature, corrosion-resistant. 2, resistance wire selection. 3, use magnesium oxide powder. 4, sealing material selection. Stainless steel heating pipe technology features: 1. electric tube end-use conditions: air burning. 2. Heater pipe: stainless steel SUS304, SUS321, SUS310S, INOC800, INCO840. 3. electric tube diameter: Φ2.0 ~ 20.0 (mm). The electric heating pipe sealing Style: EPOXY (epoxy) seal, GLASS (glass) seal. 5. Heater electrical performance: more than a year between cold place insulation value greater than 10000MΩ, leakage current is less than 0.5mA.
