Precautions for the design and use of medical electric heating tubes

(1) Try to reduce the gap between the outer diameter of the single-head electric heating tube of the mold and its insertion hole diameter. Usually, the gap between the two is less than 0.1-0.2mm. .

(2) The coaxiality and size tolerance of the mounting hole should be effectively guaranteed during processing. For example, a reamer and other tools should be used to trim the processing.

(3) Before the installation of the heating pipe, the residue left in the processing should be cleaned up. If there is any residue such as oil, it will be carbonized after heating, thus affecting the ability of heat conduction.

(4) The solar electric heating tube adopts the design of low power density and adopts a special anti-scaling treatment method, which greatly enhances the service life of the solar electric heating tube. Generally, it is made of stainless steel 316 or above, which is very corrosion-resistant and can be cleaned. Increase service life.
