Stainless steel 304 material is commonly used for electric heating pipes. The working environment is generally divided into dry burning and liquid heating. If it is dry burning, such as oven and air duct heater, it can be carbon steel or stainless steel 304. If it is a heating liquid, if it is water, use a 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 and alkali liquid, it can be made of stainless steel 316. If there is a strong acid in the liquid, stainless steel 316 should be used. PTFE and even titanium tubes.
1. Determine the power of the heating tube according to the working environment.
The power settings are mainly dry-fired electric heating pipes and liquid heating. If dry burning, a meter-long pipe is generally 1KW heating liquid, a meter-long pipe is generally 2-3KW, * large does not exceed 4KW.
2. Select the shape of the heating tube according to the user's electric heating equipment.
The shape of stainless steel heating tube is ever-changing, * simple is straight rod, U-shaped to special-shaped. Specific shapes of electric heating tubes are used.
3. Determine the wall thickness of the heating tube according to the use of the user's 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 pipe with wall thickness to make an electric heating tube.
