At about 08:30 on July 22, the workshop staff of Guizhou Yihua Chemical Co., Ltd., located in Maling Township, Xingyi City, discovered that there was a leakage in the pipeline of the conversion section. At 0845 hours, gas leaks from the pipeline began to catch fire and exploded. A total of 5 people were killed in the explosion and 6 were injured.

Obviously, the occurrence of this chemical plant accident is caused by the leakage of the pipeline. The leakage of the pipeline is caused by the leakage of the sealing surface of the pipeline. The reasons for the leakage of the sealing surface of the pipeline are: damage to the sealing surface, such as indentation, abrasion, and the middle There is a broken wire, there is dirt attached between the sealing surfaces, or the sealing ring is not well connected.

Coincidentally, on the morning of August 4, Jiangsu Changzhou Hubin Pharmaceutical Raw Materials Co., Ltd. deflagrated the chlorobenzoic acid production plant, two workers who were on duty at night were severely burned, and neighboring residents shattered windows and doors. According to investigations, the explosion was caused by the leakage of the reactor in the production process of p-chlorobenzoic acid, causing instant detonation.

Afterwards, it was learned that the cause of the accident was not that there was a failure in the main production equipment, but that an inconspicuous sealing gasket on the mixer was damaged, and that flammable and explosive materials were caused by the leakage at the damaged part. The gaskets are damaged, either due to quality defects or due to the lack of timely updates resulting in aging of the gasket.

The two accidents caused by leakage have sounded the alarm for the safe production of enterprises. As an important policy of our country, social and enterprise management is one of the important contents. Safety production refers to the personal safety of enterprises and institutions in the labor production process, equipment and product safety, and transportation safety. It not only relates to the smooth progress of production activities, but more importantly relates to the safety and health of workers, the particularity of the safety issues involved in the accident, and even the environmental issues on which future generations depend.

From the above many accidents, we can see that our protection of production safety is not to ignore, but not enough attention, or that we do not focus on the details of security issues. What is the security issue in detail? It is not the main production device, but the security protection at the sealing link.

Preventing leaks and sealing leaks is a specialized discipline. There are widespread leakage problems in the machinery and equipment used in the process industry. Hu Guozheng, chief engineer of Aizhi Industrial Technology Group, a well-known domestic sealing company, stated that “sealing makes the plant safer. Leakage is not only a cleaning problem, but also causes more serious safety hazards. Leaking flammable media is a potential fire hazard; leaked Toxic substances are harmful to the human body; even if water is leaked, they need to be promptly removed.” Many of the safety issues we read in the newspapers were not caused by leaks, but a considerable part of them were caused by seal failures. It is the original wrong operation, but it can be avoided if it is sealed. One of the most famous examples is the explosion of the Challenger spacecraft. Analyzed to analyze the failure of a small O-ring. How much does this O-ring account for the cost of the space shuttle? It may be less than one hundred millionth, but it is 100% on safety issues. Once again, sealing improves the continuity and reliability of production. People engaged in factory production know that modern production is a continuous process. Each process, each piece of equipment, and every worker is not run independently, but one after the other. When a problem occurs in one section, the loss caused by the loss is often the largest part because the following process will be stopped due to the interruption of this section. If you visit a car factory and visit a power plant, you can understand the concept of the “line”. Continuous operation is the basis of modern production. If the failure of a seal on the main process can cause a process to stop. How many sealing points in a factory may result in production stoppages? Thousands and thousands of very unremarkable places. Therefore, although the seal is small, the reliability of the seal is very important. The above adds up to how to improve the overall efficiency of modern production by improving the reliability of the seal and reduce the analysis of the overall energy consumption. As the leading company in the sealing industry, AiZhi seal has positioned "diligent, safer, and more stable modern production" as the basic problem that the sealing technology should solve for users from the very beginning, and has always taken this as the development of the enterprise. mission.

Hu Guotao, chief engineer of Aizhi Industrial Technology Group Corporation, believes that in order to prevent similar leak accidents from happening again and ensure the production safety of enterprises, it is necessary to increase technical and capital investment to ensure the safety of equipment operation and transportation, eliminate equipment failures, and eliminate Potential safety hazards; more importantly, we should pay attention to ideological considerations. We must not ignore sealing because it is a small thing, and realize the important role of sealing in the entire process of industrial production, such as energy saving, emission reduction, coherent fluency, and security assurance. This tragedy was once again staged.
