In recent years, because of the improper planning, manufacturing, use, and maintenance of cement pipes, natural gas leaks from pipelines, and the explosions caused by them increase year by year, posing a huge threat to people's lives. The detection of the defects of cement pipes must always be carried out. Let me introduce to you the shortcomings that are simply present in the cement pipe, and then prescribe the right medicine to eliminate the potential safety hazards. According to the enlightenment brought by the professional rules of pipeline operators and relevant departments and the frequent occurrence of accidents, the following shortcomings are summarized:
1. The general disadvantage is corrosion. Firstly, there are two types of corrosion and erosion. These two types of corrosion are slow and cannot be easily detected by inspectors. The other is stress corrosion cracking, which is a pipe cracking phenomenon caused by corrosion, tension and stress, which is very harmful.
2. Mechanical damage is also a shortcoming of the cement pipe. It mainly includes circular chisels and dents with circular chisels. These are usually caused by mechanical loss.
3. The shortcomings of the external cracks are attributed to the plane defects of the cement pipeline. They were simply found. The cracks were attributed to severe wear and tear, and the perforations would form cracks or leaks.
Therefore, it is necessary to test the cement pipe in a timely manner, and once the defects are found, the corresponding correction method is adopted immediately to eliminate the hidden dangers and ensure safety.
