How to choose the electric heating tube
1, the general use is more stainless steel 304 material. The working environment is generally divided into dry and liquid heating, if it is dry, such as used for oven, air duct heater, can use carbon steel material, can also use stainless steel 304 material. If it is heating liquid, if it is water, use stainless steel electric heating tube, this stainless steel is generally stainless steel 304 material, if it is oil, can use carbon steel or stainless steel 304 material. If it is with a weak acid alkaline liquid, can use stainless steel 316 material. If there is a strong acid in the liquid, stainless steel 316, PTFE and even titanium tube should be used.
2. Determine the power of the heating tube according to the working environment.
The power setting is mainly for dry-burning electric heating tubes and liquid heating. If it is dry-burning, the pipe with a length of one meter is generally 1KW and the liquid is heated. Generally, a one-meter-length pipe is used for 2-3KW, not more than 4KW.
3. Choose the shape of the heating tube according to the customer's electric heating equipment.
The shape of the stainless steel heating tube is ever-changing, among which the simple is straight rod, U-shaped and then to the special shape. The specific shape of the electric heating tube is used.
4. Determine the wall thickness of the heating tube according to the use of the customer's heating tube
Generally, the wall thickness of the heating pipe is 0.8mm, but according to the working environment of the heating pipe, such as the case of high water pressure, it is necessary to use the wall thickness of the seamless stainless steel pipe to make the electric heating tube.
5. When buying, ask the manufacturer, the internal material of the heating tube.
Why are many heating tubes similar in appearance, but the prices vary greatly? Is the inside of the internal material, is important to the 2 kinds of material is the insulating powder and alloy wire. Insulation powder, the poor will use quartz sand, good will use insulation modified magnesium oxide powder. In addition, alloy wire, generally use iron-chromium aluminum, according to the requirements and grade of tube production, can use nickel-chromium alloy wire. As the saying is, a penny, a penny. It is recommended that customers do not covet cheap, so as not to buy inferior products.
