Today, we received new customers directly to our company's production workshop, bringing the drawings of W-shaped tubular heating element, which we produce and process. In the exchange, the first choice is to make optional materials. The W-shaped heating element is usually used in two kinds of materials. One is the ordinary carbon steel tube to manufacture the heating element; the other is the stainless steel 304 tube as the material to make the tubular heater. The heating of the pipes of the two materials is basically the same, but the price of the stainless steel pipes is slightly higher than that of the carbon steel pipes. In the communication with our technicians, we know that they are used in corrosive gases, and we also know that the customer's situation will be left unused for a long time. Address the environmental and time issues that customers are talking about. Our company's technicians suggested that if the carbon steel pipe is used in a corrosive environment, it is easy to rust or not used for a long time, and it is easy to cause the heating pipe made of carbon steel to rust, and the heating pipe cannot be used. It is recommended to use a stainless steel 304 tube as a material for the stainless steel heating tubular according to the condition of the household, the use environment, and the long-term life.
Rules for Magnesium Oxide in Electric Heating element:
1. Magnesium oxide powder is located between the heating wire and the pipe wall for insulation between the heating wire and the pipe wall. At the same time, the magnesium oxide powder has good thermal conductivity. However, the magnesium oxide powder has a strong hygroscopic property, so it is subjected to moisture-proof treatment (magnesium oxide powder modification or electric heating tube sealing treatment) during use.
2. Magnesium oxide powder can be divided into low temperature powder and high temperature powder according to the temperature range used. The low temperature powder can only be used below 400 ° C, generally modified magnesium oxide powder.
3. Magnesium oxide powder is granulated, and the magnesia powder used for the electric heating tube is configured by arranging magnesium oxide powder particles of different thickness according to a certain ratio (mesh ratio).
The above is the knowledge of magnesium oxide powder organized by Yancheng Huajiang Power Manager Zhang, especially the knowledge of magnesium oxide powder in the electric heating tube. I hope to give you a deeper understanding of the electric heating tube. It seems simple. In fact, there are still many rules.
