Reasons for frequent damage of dry heating heating pipes

1. There is a problem with the quality of the heating tube: the tube wall is too thin, the material grade is too low, and there are seam tubes;

2. There is a problem with the quality of using magnesium oxide: there are too many impurities in it, or there are metal objects such as iron filings;

3. The electric heating tube has a leakage problem: the tube is not well sealed, the heating wire inside is unevenly arranged, and the resistance wire is not located in the middle of the tube.
