1, the most common use of customers is 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, it can be made of carbon steel or stainless steel 304. If it is heated liquid, if it is water, use 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 alkaline liquid, it can be made of stainless steel 316. If there is strong acid in the liquid, stainless steel 316, Teflon or even titanium tube should be used.


2. Determine the power of the heating tube according to the working environment.


The setting of power is mainly to dry the electric heating pipe and the liquid heating. If the dry burning is done, the pipe of one meter length is generally 1KW, and the liquid is heated. Generally, the pipe of one meter length is 2-3KW, and the maximum is more than 4KW.


3. Select the shape of the heating tube according to the customer's electric heating equipment.

The shape of the stainless steel heating tube is ever-changing, the simplest is the straight rod, the U-shaped and then the shaped. The specific case of the electric heating tube of a specific shape is adopted.


4. Determine the wall thickness of the heating pipe according to the customer's use of the heating pipe.


Generally, the wall thickness of the heating pipe is 0.8 mm, but according to the working environment of the heating pipe, for example, in the case of a large water pressure, it is necessary to use a seamless stainless steel pipe having a thick wall thickness to make an electric heating pipe.


5, when you buy, ask the manufacturer, the internal material of the heating tube
