The thickness of the bottom of the heating kettle was detected to be thin and spotty.

According to the situation you described, the bottom of the heating kettle has local thickness thinning and spots, and the material is asphalt. This is likely to be cavitation. Cavitation refers to the damage caused by fluid or gas in the medium to the metal surface when it flows at high speed, resulting in pits, bulges and other phenomena on the surface. In high temperature and high pressure environments, asphalt may react with gases to produce corrosive substances, causing cavitation damage to metal surfaces. It is recommended to conduct further inspection and maintenance on the bottom of the kettle to avoid exacerbating the problem and causing safety accidents. -

The kettle is under normal pressure, how to effectively avoid it?

If you wish to avoid the atmospheric pressure of your kettle, here are some tips that may be helpful: 1. Regular inspection and maintenance: To ensure that the valves, pipes and other parts of the kettle are in normal working condition, regular inspection and maintenance are required. 2. Set safety thresholds: Set up equipment or procedures for the kettle to maintain a safe condition. For example, alarms or automatic shutdown procedures can be set up to ensure that the kettle never reaches excessive pressure. 3. Periodic detection: Regularly check the sealing and safety of the kettle, especially check whether there are leaks in pipes and connections. 4. Train employees: Provide detailed training on kettle operation and safety requirements and ensure all employees comply with safety regulations. 5. Use professional equipment: Choosing high-quality, reliable equipment and using and maintaining it according to the manufacturer's recommendations will help ensure that the kettle remains in a safe condition. In short, the normal pressure issue of the kettle is very important and should be paid enough attention to. Through effective methods such as regular inspections, setting safety thresholds, periodic testing, employee training and the use of professional equipment, the atmospheric pressure risk of the kettle can be minimized. -

The material asphalt is 360 degrees and flows into the first kettle by gravity. The bottom of the kettle is heated by radiation and then enters the next process kettle. The next process kettle is also heated by radiation and then enters the next process kettle. It is difficult to understand why the first heating kettle produces such a situation? There is no similar situation in the post-process kettle.

It is difficult to judge without actual pictures. It is recommended to observe for a period of time to find out the problem.

The physical drilling is actually the same thickness in comparison.

There are excessive substances in the materials, such as sulfur, phosphorus, chloride, etc. Our unit uses 15CrMoR material.

Can this be analyzed with a sample, or what instrument can be used to analyze it?
