In industrial production, almost all single headed pipes need to be fixed. So, how to fix single headed pipes correctly in practical applications?
1. U-shaped single head tubes, it can be said that basic single head electric heating tubes can be installed using fasteners.
2. The single head tube does not need to be fixed during the common mold heating process, it is directly installed in the heating hole for heat transfer.
3. The flange type single head pipe is characterized by its easy installation. The flange installation method is generally divided into flat flange installation and threaded flange installation. Flat flange installation requires the female flange to be welded to the box, and then tightly fitted with the flange on the flat flange single head double spring electric heating pipe; The installation of threaded flange involves tapping on the fixing plate and then directly screwing the threaded flange onto it. A fixed single head pipe needs to be installed, and the general method is to weld an installation thread on the basis of the single head pipe, which is usually 6 inches, 1 inch, etc.
The outermost edge of a single head heating tube is a metal sheath, and the material of the sheath can be selected according to different usage environments and temperatures.
Then, insert the corresponding thickness of resistance wire calculated based on the resistance value into the metal sleeve. Generally, the materials of resistance wire include iron chromium aluminum wire and nickel chromium wire.
Then, a modified magnesium oxide powder with excellent thermal conductivity and insulation should be tightly filled around the resistance wire. The magnesium oxide powder should not be mixed with impurities such as grass dust, nor should it contain water. This will cause uneven heating or even conductivity on the surface of the heating tube. Generally, there are carbon steel, stainless steel 201, stainless steel 304, and stainless steel.
To ensure the best performance of the electric heating tube, correct fixation is a prerequisite. Have you mastered the fixation method? In addition, there are many details that can affect the effectiveness of using electric heating tubes.
The temperature resistance of materials such as stainless steel 310S varies from low to high. A single head heating rod is used to heat corrosive liquids or gases, and the material of the metal sheath should be stainless steel 316L, PTFE coating, and other materials. The above are the correct fixing methods for single headed pipes.
Finally, use a shrinking machine to shrink the metal casing to the required diameter.
