How to select electric Heat pipe
Jun 26, 2017

1, the most commonly used customers are stainless steel 304 material. Working environment is generally divided into dry and liquid heating, if it is dry burning, such as for oven, duct-type heaters, you can use carbon steel quality, can also use stainless steel 304 material. If the liquid is heated, if water, stainless steel electric tube, this stainless steel is generally 304 stainless steel material, if oil, you can use carbon steel or stainless steel 304 material. If you have a weak acid alkaline liquid, you can use stainless steel 316 material. If the liquid has strong acid, it should be stainless steel 316, PTFE or even titanium tube.

2, according to the working environment to determine the power of the heating pipe.

The power of the setting, mainly is the dry-burning electric tube and liquid heating, dry, generally a meters length of pipe 1KW, heating liquid, is generally a meters length of the pipe to do 2-3kw, the largest not more than 4KW.

3, according to the customer's heating equipment selection of the shape of the heating tube.

The shape of stainless steel heating tube is ever-changing, the simplest is straight rod, U-shaped and then to special. Specific situation of the use of specific shape of the electric tube.

4, according to the customer's use of heating pipe to determine the wall thickness of the heating pipe

The wall thickness of the general heating pipe is 0.8mm, however, according to the working environment of the heat pipe, for example, under the condition of large hydraulic pressure, we need to use seamless stainless steel pipe with thick wall to make the electric heating pipe.

5, the purchase time to ask the manufacturer, heating pipe production of internal materials

Why do the heating tubes look similar to each other, and the price will have great error? That is, inside the internal material, the most important 2 kinds of materials are insulating powder and alloy wire. Insulating powder, the difference will use quartz sand, good will use the insulation modified Magnesia powder. In addition, alloy wire, the general use of iron chrome aluminum, according to the requirements of the pipe production and grade, you can use Ni-cr alloy wire. The so-called, a penny, a penny. Advised the broad masses of customers, do not covet cheap, so as not to buy inferior products.
