Electric Heating Tube for Steamer

1.Brief introduction of steamer electric heating tube

The steamer electric heating tube is a double-ended heating tube with a metal tube as the protective shell. High quality electric heating alloy wires (nickel chromium, iron chromium alloy heating wires) are evenly distributed along the central axis of the tube, and the gaps are tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation. The ends of the tube mouth are sealed with silicone, and after other processes, it can be made into U-shaped, double U-shaped, m-shaped, flange shaped, and mosquito repellent incense type, Circular and other shapes.

2.Application scenarios of steamer electric heating tube

Electric heating tubes for steamers are often used in heating equipment such as steamers and rice steamers.

3.Main technical parameters of electric heating tube for steamer

①Shell material: stainless steel 304, stainless steel 321, stainless steel 310S, Ingle 800, Ingle 840, etc.

②Heating wire material: 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, Cr20Ni80, etc.

③Insulation filler: medium temperature insulating magnesium oxide powder, high temperature insulating magnesium oxide powder, etc.

④Rated voltage: 110V, 220V, 380V, etc.

⑤Power: The power is determined according to the total length of the heating area of ​​the electric heating tube of the steamer and the use environment.Normally, 3KW power is used in the heating area of ​​one meter. When the heated water has serious scale, it is recommended to use 1.5-2KW.

⑥Pipe diameter: 8mm-30mm

⑦Length: according to customer requirements

⑧Cold state insulation resistance: cold state insulation resistance should not be less than 50MΩ during factory inspection; after sealing test, the insulation resistance after long-term storage or use should not be less than 1MΩ

⑨Cold state leakage current: ≤ 0.5 mA

⑩Cold insulation: 1600v. 1/seg

4.Product advantages of steamer electric heating tube

①Non-standard customization, flexible production, to meet the heating requirements of various equipment.

②Heats up fast.

③Fasteners can be added flexibly.

5.Precautions for electric heating tube of steamer

①If the installation hole has been opened before ordering, the diameter of the electric heating tube of the steamer or the thread diameter of the fastener should be determined according to the installation hole diameter

②The electric heating tube of the steamer must have temperature control, and the temperature should be controlled within the applicable range of the material

6.Instructions for Wiring the Electric Heating Tube of the Steamer

Connect a single tube to the power supply: connect directly according to the voltage, usually 220V, one live wire and one neutral wire; 380V, if there are only 2 binding posts, then just connect 2 live wires.

Multiple tubes connected to the power supply: can be adopted according to the actual situation: parallel connection, series connection, delta connection or Y connection, etc.
