Hexagonal spiral heating tube wholesale heat conduction tube high power heater fast heating water tank 220V 380V high power
In response to your wholesale demand for "hexagonal spiral heating tubes, high-power heaters, and fast-heating water tanks," these products are widely used in industrial water tanks, boilers, air energy, and heat conduction oil furnaces. Based on the current supply situation in the B2B market, here is a summary of mainstream product specifications, price ranges, and procurement suggestions:
1. Mainstream Specifications and Price Reference
1. Hexagonal Threaded Heating Tube (Commonly Used in Industrial Water Tanks/Boilers)
Common sizes: Common thread specifications include 47mm (about 1.5 inches), 58mm (about 2 inches), and DN40/DN50 female thread interfaces.
Voltage and power: Supports 220V and 380V voltages, with power coverage ranging from 3KW to 18KW.
Material selection: 304 stainless steel is commonly used; for highly corrosive liquids (such as acid and alkali solutions), 316L material can be selected.
Wholesale price: Depending on power and material, the wholesale price per unit typically ranges from 89 yuan to 241 yuan. For example, a 304 material 220V/3KW heating tube is about 89 yuan, while a 380V/18KW high-power tube is about 241 yuan.
2. Small Water Tank Heating Tube (Fast Heating)
Product form: Mostly U-shaped submersible heating tubes or single-head threaded tubes, suitable for small pools, aquaculture, cattle and sheep water troughs, and household water heaters.
Wholesale price: The price is relatively affordable. The wholesale price for conventional 220V/1500W-3000W heating tubes is around 5 yuan to 30 yuan.
2. Core Technology and Customization Parameters
For high-power industrial heaters, manufacturers usually support non-standard customization. When purchasing or contacting manufacturers, you can refer to the following technical indicators:
Structural design: The interior uses spiral electric heating wire, and the gaps are densely filled with crystalline magnesium oxide powder to ensure good thermal conductivity and insulation performance.
Size customization: The tube diameter is typically between Φ6.6-16mm, and the length can be customized within the range of 20-6000mm according to installation requirements.
Anti-corrosion process: If the heating medium is prone to scaling or is corrosive, you can request the manufacturer to add an anti-corrosion coating or anti-scaling coating on the tube surface to extend service life.
Wiring method: 380V high-power heating tubes usually support star connection or delta connection, and are equipped with K-type thermocouples or PT100 temperature sensing elements for precise temperature control.
3. Industrial Belt Distribution and Procurement Suggestions
Source industrial belt: The core production industrial belts for electric heating tubes and explosion-proof heaters in China are mainly concentrated in Jiangsu Province (such as Yancheng, Taizhou, Yangzhou, Xinghua, etc.) as well as Guangdong, Zhejiang, and other places. These areas have dense manufacturers, support processing with drawings and samples, and have obvious cost advantages for wholesale purchasing.
Safety and usage precautions:
Strictly prohibit dry burning: Submersible heating tubes must ensure that the liquid level is higher than the heating area. Dry burning without water will cause the tube body to blacken, expand, or even burn out.
Regular descaling: For media with severe scaling, the tube body needs to be cleaned regularly; otherwise, heat cannot be dissipated, leading to damage to the heating tube.
Installation specifications: When installing with flanges or threads, ensure good end face sealing to prevent water leakage and electric leakage.
If you need large-scale procurement, it is recommended to directly inquire with source manufacturers in Yancheng or Taizhou, Jiangsu (such as electric heating appliance factories that support customized processing), specifying your required voltage, power, thread size, and material. This usually allows you to obtain better tiered wholesale prices.
