Causes of tube bursts in electric heating tubes

Causes of tube bursts in electric heating tubes

1. The wall thickness of the pipe is too thin, the material is selected incorrectly or the quality is problematic, and the pipe with seams is used. The thickness of the pipe wall is generally 0.8 units. If it is too thin, it will be easily damaged by external force or use.

2. Stainless steel pipes can be divided into seamed pipes and seamless pipes according to different processing forms. Seamed pipes are a whole pipe that is not easy to be damaged, while seamless pipes are welded by steel bars and are relatively easy to burst. Phenomenon. Generally, if pipe bursts occur frequently, you can consider communicating with the manufacturer to make the pipe wall thicker or choose seamless pipes to ensure normal use and service life.

3. If the magnesium oxide powder inside the electric heating tube is damp, there will be the possibility of tube bursting. In this respect, the manufacturer's production technology is required to be perfect, and the processing technology is excellent.

4. The heating tube power setting is too high, the surface load is too large, and the internal temperature is too high, which will easily cause the internal expansion of the electric heating tube, which will cause the tube to burst.

5. There are many kinds of magnesium oxide powder, the best of which is modified magnesium oxide powder with high temperature resistance. If inferior magnesia powder is used, when the stainless steel heating tube is working, the internal expansion of the stainless steel heating tube will also occur, which will cause the tube to burst.

6. The material of the outer tube of the electric heating tube may be the wall thickness of the tube, or it may be a seam tube, which causes the heating tube to be easy to crack.

7. The water used by the heating tube for heating may mostly be groundwater or tap water, which has many impurities and is easy to form scale. Too much and thick scale will cause the internal temperature of the electric heating tube to fail to diffuse and cause the electric heating tube to burst.
