How to choose electric heating pipe is a technical activity. There are many types of electric heating pipes, which can be used in different environments.
1, the most commonly used is the stainless steel 304 material.
The working environment is generally divided into dry burning and liquid heating. If it is dry burning, such as for oven, air duct heater, it can be made of carbon steel or stainless steel 304. If it is heated liquid, if it is water, use stainless steel electric heating tube. This stainless steel is generally made of stainless steel 304. If it is oil, it can be made of carbon steel or stainless steel 304. If it is a weak acid alkaline liquid, it can be made of stainless steel 316. If there is strong acid in the liquid, stainless steel 316, Teflon or even titanium tube should be used.
2. Determine the power of the heating tube according to the working environment.
Power setting, mainly dry burning electric heating pipe and liquid heating, dry burning, generally one meter length of pipe to do 1KW, heating liquid, generally one meter length of pipe to do 2-3KW, the maximum does not exceed 4KW.
3. Select 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, the simplest is the straight rod, the U-shaped and then the shaped. The specific case of the electric heating tube of a specific shape is adopted.
4. According to the customer's use of the heating pipe to determine the wall thickness of the heating pipe. The performance curve of the heating pipe is generally 0.8mm, but according to the working environment of the heating pipe, such as large water pressure In this case, it is necessary to use a seamless stainless steel tube with a thick wall thickness to make an electric heating tube.
5, when buying, ask the manufacturer, why the internal material heating tube made by electric heating tube is similar in appearance, and the price will have a big error? That is the internal material inside, the most important two kinds of materials inside are insulating powder And alloy wire. Insulating powder, quartz sand will be used poorly, and insulating modified magnesia powder will be used. In addition, the alloy wire, generally iron chrome aluminum, according to the requirements and grades of pipe production, nickel-chromium alloy wire can be used.
