Explosion proof tools: why explosion-proof

1、 Design principles of explosion-proof tools
Explosion proof tool is a special tool, which is mainly used for operation and maintenance in flammable and explosive gas environment. The design principles of explosion-proof tools include the following:
1. Anti static: The material selection of explosion-proof tools should avoid using live materials to prevent sparks and potential hazards.
2. Anti friction: The surface coating of explosion-proof tools should have good anti friction performance to reduce the generation of sparks.
3. Explosion proof housing: The housing of explosion-proof tools should have explosion-proof performance to prevent fragments from splashing during explosion.
4. Corrosion prevention: Explosion proof tools are often used in harsh environments, so they need to have anti-corrosion performance to extend the tool's service life.
2、 Application scope of explosion-proof tools
Explosion proof tools are mainly used for operation and maintenance in flammable and explosive gas environment. These environments include:
1. Petrochemical industry: In industries such as refining, chemical engineering, and natural gas extraction, explosion-proof tools are required due to the handling and transportation of flammable and explosive gases.
2. Coal mining industry: In coal mines, there is a large amount of flammable substances such as coal dust and oil fumes. The use of ordinary tools can generate sparks and cause danger, so explosion-proof tools are needed.
3. Aerospace industry: In the maintenance process of aircraft, rockets, and other aircraft, there are many flammable and explosive gases involved, so explosion-proof tools need to be used.
