A must-see for electrician/petrochemical/coal mining practitioners: Have you chosen the right explosion-proof tool?
May. 09, 2025
The material of the explosion-proof tool is copper alloy, due to the good thermal conductivity of copper and the characteristics of almost no carbon, so that when the tool and the object are rubbed or impacted, the heat generated in a short time is absorbed and conducted, and the other reason is that the copper itself is relatively soft, and there is a good concession when friction and impact, and it is not easy to produce tiny metal particles, and there are almost no sparks, so the explosion-proof tool is also called a non-spark tool. Explosion-proof tools play a vital role in all kinds of industrial sites and flammable and explosive environments.
Common explosion-proof tools
Explosion-proof adjustable wrench is a tool specially designed for flammable and explosive environments, its main feature is that it does not produce sparks when it hits metal machinery or friction, and is suitable for oil, petrochemical, natural gas and other flammable and explosive dangerous places. The opening width of the explosion-proof wrench can be adjusted within a certain range, allowing the tightening and loosening of nuts and bolts of different sizes. Explosion-proof percussion wrench Explosion-proof percussion wrench is a special tool used in flammable and explosive environments, mainly used in petroleum refining, petrochemical industry, coal mines, oil fields and other places. Its main materials include aluminum bronze and beryllium bronze, which have good electrical conductivity and anti-explosion properties. Explosion-proof dual-purpose wrench The design features of the explosion-proof dual-purpose wrench include that both sides can be used to adapt to different work needs, mainly used for operation in a flammable and explosive environment, the material is usually copper alloy, with good thermal conductivity and low hardness, and can not produce sparks when rubbing and impacting, to ensure the safety of operation. Explosion-proof crowbar The main materials of explosion-proof crowbars include aluminum bronze alloy and beryllium bronze alloy, which have good thermal conductivity and low hardness, which can reduce the generation of sparks when working. It is widely used in flammable and explosive places such as petroleum refining plants, coal mines, oil fields, chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, pharmaceutical industry, etc. Explosion-proof pliers The explosion-proof pliers are made of copper alloy, and the good thermal conductivity and almost carbon-free characteristics of copper make it able to quickly absorb and conduct heat during use, avoiding the accumulation of heat generated in a short period of time to form sparks. In addition, the softness of copper gives it good retraction when rubbing and impacting, and it is not easy to produce tiny metal particles, further reducing the risk of sparks. Explosion-proof round head hammer Explosion-proof hammers are usually made of high-quality materials, and the hammer head is made of high-strength copper alloy to ensure that it has strong impact resistance and is not easy to break or fall off, which is widely used in petroleum, petrochemical, chemical, mining, power generation, pharmaceutical and other industries. It is designed to ensure that no sparks are generated during use, thus preventing the explosion of flammable gases due to friction or impact, and protecting the safety of people and property. Explosion-proof octagonal hammer Explosion-proof octagonal hammer is a tool specially designed for flammable and explosive occasions, mainly used to hammer harder objects to avoid mechanical sparks during operation to detonate explosive gases. It is usually made of beryllium bronze alloy and aluminum bronze alloy, and the handle can be a wooden or fiber handle. Explosion-proof chain hoist Explosion-proof chain block is a kind of manual lifting machinery that is easy to use and easy to carry, with aluminum bronze and beryllium bronze as the blank, the chain block shell is made of H62 copper alloy material, and its rotating gear has been heat treated at high temperature and has high wear resistance. It is widely used in petroleum, petrochemical, gas stations, oil depots, gas production, chemical industry, military industry, electric power, mining, electronics, railways and other potential fire and explosion hazardous environments. Precautions for use Ensure that the Non Sparking tools purchased meet the explosion-proof performance requirements, and avoid using them as ordinary steel tools in non-hazardous places, so as not to lose their due explosion-proof performance. Explosion-proof tools should be stored in a dry place, and after use, the surface dirt and accumulation should be wiped off, and storage in humid environments and media should be avoided, so as to avoid tool corrosion affecting the use performance. When using percussion tools, attention should be paid to intermittent use to avoid long-term continuous percussion that causes the tool to heat up. When using explosion-proof tools, they should be reasonably selected according to their needs, and they should not be replaced by small ones. Especially when using live wrenches, pipe wrenches, and dead wrenches, it is necessary to pay attention to the requirements of the direction of force, and do not twist arbitrarily. When using explosion-proof tools, it is necessary to strictly follow the relevant national standards and industry standards, such as the "Ten Regulations on Fire and Explosion Prevention in Oil and Gas Tank Farms" issued by the State Administration of Work Safety, and the "Safety Regulations on Explosion Hazardous Places" issued by the former Ministry of Labor. In addition, the industry standard QB/T 2613 "Explosion-Proof Tools" series provides detailed guidance and specifications. Explosion-proof tools are mainly divided into aluminum-copper alloy (commonly known as aluminum-bronze) explosion-proof tools and beryllium bronze alloy explosion-proof tools. Aluminum-copper alloy tools have excellent thermal and electrical conductivity, and are suitable for use in strong magnetic field environments; Beryllium bronze alloy tools also have excellent thermal and electrical conductivity and are non-magnetic, making them suitable for working in strong magnetic field environments.
