1, the general customer is the most used 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, you can use carbon steel material, you can also use stainless steel 304 material. If it is heating liquid, if it is water, use stainless steel electric tube, this stainless steel is generally 304 stainless steel material, if oil, you can use carbon steel or 304 stainless steel material. If it has weak acid and alkaline liquid, stainless steel 316 can be used. If there is a strong acid in the liquid, stainless steel 316, polytetrafluoroethylene or even titanium tubes should be used.
2, according to the working environment to determine the power of the tubular electric heater: the power is set, mainly dry heating heat pipe and liquid heating, dry burning, generally a meter length of the tube to do 1KW, heating liquid, generally a meter length of the pipe to do 2-3kW, the maximum is not more than 4KW.
3, according to the customer’s electric heating equipment to choose the shape of the electric heating tube: stainless steel heating tube shape is ever-changing, the simplest is straight rod, U-shaped and then shaped. The specific situation uses the specific shape of the electric heat pipe.
4, according to the use of the customer’s heating tube to determine the wall thickness of the heating tube: generally, the wall thickness of the heating tube is 0.8mm, but according to the working environment of the heating tube, such as large water pressure, it is necessary to use a seamless stainless steel tube with wall thickness to make an electric tube.
5, when buying, ask the manufacturer, the internal material of the heating control: why are many heating pipes similar in appearance, and the price will have a big error? That is the internal material inside, the two most important materials inside are insulation powder and alloy wire. Insulation powder, poor will use quartz sand, good will use insulation modified magnesium oxide powder. In addition, the alloy wire, generally with iron chromium aluminum, according to the requirements and grades of pipe production, nickel chromium alloy wire can be used. As the saying goes, you get what you pay for. It is recommended that our customers do not covet cheap, so as not to buy inferior products.
