The characteristics of W type stainless steel heating tube

Product features:

1 small volume, big power: the inside of the electric heater mainly uses the cluster type tubular heating element, each cluster type tubular electric heating element maximum power up to 5000KW.

2 fast thermal response, high precision of temperature control, high comprehensive heat efficiency.

3 wide application range, strong adaptability: the circulating heater can be applied to the anti explosion orordinary occasions, explosion-proof grade up to B grade and C grade of it, its voltage up to 20Mpa. According to user needs and cylinder body adopts a vertical or horizontal installation.

4 high heating temperature: the heater design maximum working temperature of 850 DEG C, the heat exchanger is generally not available.

5 fully automatic control: through the heater circuit design, automatic control parameters can be conveniently realized outlet temperature, pressure, flow, and can be connected with the computer network, the realization of human-computer dialogue.

6 long life, high reliability: the heater adopts special manufacturing electric materials, plus the design of powerload is more reasonable, the heater adopts multiple protection, so that the heater safety and the service life is greatly increased.

7 stainless steel electric heating tube is a metal tube shell, along the inside of the tube center shaft to uniform spiral electric heating wire (Cr, Fe Cr alloy) the gap filling compaction with good insulation thermal conductivity properties of magnesia, silica gel or ceramic pipe ends are sealed, the metal sheathed heating element can be heated air, mold and all kinds of liquid metal. ] uniform distribution of high temperature resistance wire in high temperature resistant stainless steel seamless tube, the gap part densely filled with thermal properties and crystallization of magnesium oxide insulation performance are good, the structure is not only advanced, high thermal efficiency, and uniform heating, when the high temperature resistance wire of electric current in thepass out of date, the heat generated by the surface diffusion into the metal tube the crystallization ofmagnesium oxide powder, and then transferred to the heated part or the air, achieve the purpose of heating.
