Why explosion-proof tools?

In the manufacturing process of explosion-proof tools, his explosion-proof performance mainly comes from his manufacturing materials. The chemical content of the materials is not less than 99.75, and the slag composition produced cannot be greater than 0.05. Random sampling is required. Qualitative stones are called explosion-proof materials. Tools made of this material are called explosion-proof tools, and the hardness of explosion-proof tools is not less than HRC35 degrees or more, the spark of the tool comes from the manufactured impurities. If the output is more than 0.05, the impurities will produce impact sparks and detonate gas. Such tools are not called explosion-proof tools.

Why use explosion-proof tools in special areas?

As early as 30 years ago, our petrochemical industry, oil refining, especially the flammable and explosive places in transportation, had to use a lot of foreign exchange to import foreign explosion-proof tools due to the frequent occurrence of spark explosion accidents caused by impact, resulting in serious lack of property and lack of personal safety. At that time, the price of foreign explosion-proof tools was 4.5 times that of our present price, After careful market research, evaluation and investigation. According to China's explosion-proof tools, for the production of enterprises, the manufacture of China's explosion-proof tools, after three years of efforts, thousands of experiments, in 1953 to produce a qualified explosion-proof tools, to fill the gap.

What tools are safe?

For safe explosion-proof tools, the manufacturer, trademark, material and explosion-proof grade shall be marked on each tool when sold, and the certificate shall be pasted. Products that cannot provide material report shall not be used. So we see at which level is what level to dare to stick what level, you can choose to use different levels of explosion-proof tools in different places.

Qingdao 112 explosion, November 22, 2013, the oil pipe leak, in the formation of dense space within the scope of the explosion. 62 people were killed, 136 were injured and the economic losses were 0.75 billion. The reason he did not use explosion-proof hydraulic pressure, a spark appeared, detonated the explosive gas. The 728 explosion in Jiangsu was also operating in violation of regulations, causing explosive gas and causing accidents of_property and personal safety. On October 31, 2000 in Tianjin, the discharged gas contained cement slurry and oil, as well as hydrogen sulfide, forming mist, peculiar smell in the air, excessive wellhead pressure, and flammable substances such as hydrogen sulfide in the air, which were difficult to control. The rescue team took decisive measures and adopted explosion-proof safety to avoid disaster accidents. According to the on-site investigation, the explosion-proof tools just used about half a month ago came in handy. If we pay attention to explosion accidents in Qingdao, if explosion-proof tools are used, such accidents will not occur. Japanese industries are using explosion-proof tools. This kind of turn was made by China for him five years ago. Let me talk about the current market situation of explosion-proof tools. The use awareness of explosion-proof tools in our country is very weak, and there is also a fluke mentality. Because we don't understand the concept of explosion-proof tools at all, we often talk about explosion-proof tools as copper tools, which leads to market confusion. This is wrong. Explosion-proof tools and copper tools are two different concepts, and copper tools do not represent explosion-proof tools. At present, there are two kinds of explosion-proof tools in China, one is beryllium bronze explosion-proof tools, and the other is aluminum bronze explosion-proof tools. The material is uneven. Tools made together are called copper tools. Tools made of this material are prone to sparks, have no strength and are easy to break. In 2004, two employees of a certain chemical plant were burned to death on the spot while cleaning up oil tanks. The tool used generated sparks in the friction, which detonated the gas and was burned to death on the spot. After the analysis, it was an explosion-proof tool. It was found that the manufacturer had a joke in the prosecution responsibility. The manufacturer did not admit that it was an explosion-proof tool, but a copper tool, and the seller also indicated that it was a copper tool. So this kind of situation can't happen again.

Explosion-proof tools, also known as safety tools, are mainly used for flammable and explosive, friction does not produce sparks, effectively preventing explosions. If the personnel used such tools at that time,_would not have caused a 1122 explosion. The manufacture of explosion-proof tools starts with his raw materials. Explosion-proof tools are a kind of safety tools that cannot be replaced by tools, that is, to achieve his safety factor, and also to have his stable experience performance. As we all know, sparks in tools are caused by impurities in products, and impurities in materials cannot be more than 0.05, so there should be a complete inspection system for materials,_is your material_should be controlled on the technical index of explosion-proof tools. After a reasonable analysis, to meet his relevant standards. In this way, you go through the high-tech formula accommodation, in the selection of different gases, do performance experiments, do friction experiments,_manufacturing tool materials, is qualified. At present, our explosion-proof tools in China have the corresponding standards in the world. After the tools are formed, all aspects of the tools should be inspected, from material inspection to performance inspection of the made tools, torque, hardness and performance should be inspected.
