Causes of quartz heating tube burst

What are the causes of quartz heating tube bursts? Let's take a brief look:

1. Poor raw material quality. While quality quartz heating tubes are typically made from high-quality dehydroxylated quartz, many manufacturers use undehydroxylated quartz tubes to save costs, leading to bursts during use.

2. Poor manufacturing process. If the sealing process is not done with the right technique, slow leaks can occur, causing bursts within seconds.

3. Incorrect model selection. Selecting a 220V heating tube for a 380V voltage and then incorrectly wiring it causes the tube to overheat and burst.

4. The quartz heating tube manufacturer's design does not meet standards, with excessive power per meter. This causes the internal temperature of the tube to expand and burst.

5. The shielding gas does not meet process requirements, resulting in heat accumulation and burst.

6. The wall thickness of the infrared quartz heating tube is too thin, not meeting production requirements.

7. The user mixes infrared heating tubes, using heating elements originally designed for mold heating directly for air dry heating, or using heating elements designed for liquid heating for air dry heating. This can cause tube bursts.

8. Quartz heating tubes are damaged by external impact or sudden shock during use.

9. When heating media such as water or thermal oil, the quartz heating tubes contain a high concentration of impurities, which rapidly form scale or carbon deposits. Failure to clean the tube surface can lead to a buildup of contaminants. This prevents the surface of the heating tube from dissipating heat, causing heat accumulation and excessive internal temperatures, leading to cracking and bursting.

10. Failure to temperature-control the quartz heating tubes, causing them to operate at extreme temperatures for extended periods.

11. Using a delta connection instead of a star connection is incorrect.
