How to choose the material of the heating element?
1. Stainless steel 304 is the most commonly used by general customers. The working environment is generally divided into dry burning and liquid heating. If it is dry burning, for example, it is used in ovens and duct heaters. It can be made of carbon steel or stainless steel 304. If it is heating liquid, if it is water, use stainless steel heating element. 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 has weak acid and alkaline liquids, stainless steel 316 can be used. If there is strong acid in the liquid, stainless steel 316, polytetrafluoroethylene or even titanium pipe should be used.
2. Determine the power of the heating element according to the working environment.
The power setting is mainly for dry heating heating elements and liquid heating. For dry heating, a pipe with a length of one meter is generally used for 1KW, and the heating liquid is generally a pipe with a length of one meter for 2-3KW, and the maximum is not more than 4KW.
3. Choose the shape of the heating element according to the customer's heating equipment.
The shape of the stainless steel heating element is ever-changing, the simplest is the straight rod, the U-shaped and then the special-shaped. Specific conditions use heating elements of specific shapes.
4. Determine the wall thickness of the heating element according to the usage of the customer's heating element. Generally, the wall thickness of the heating element is 0.8mm, but according to the working environment of the heating element, such as the case of high water pressure, the wall thickness is required Thicker seamless stainless steel tubes to make heating elements.
5. Ask the manufacturer about the internal material of the heating element when buying.
Why are many heating elements similar in appearance, but the price will have a big error? That is the internal material inside. The two most important internal materials are insulating powder and alloy wire. Insulating powder, the poor ones will use quartz sand, the good ones will use insulating modified MGO powder. In addition, the alloy wire is generally iron-chromium-aluminum. According to the requirements and grades of pipe production, nickel-chromium alloy wires can be used. As the saying goes, you get what you pay for. It is recommended that customers not be greedy for cheap, so as not to buy inferior products.
