Non sparking safety tools
(1)What is a "non-sparking" tool?
"Non-sparking", "spark reduced", "spark-resistant" or "spark-proof" tools are names given to tools made of metals such as brass, bronze, Monel metal (copper-nickel alloy), copper-aluminum alloys (aluminum bronze), or copper-beryllium alloys (beryllium bronze).
Commonly used hand tools are often manufactured of steel alloys. Preferred "non-sparking" metals have less tensile strength than steels usually used to make tools. A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions. It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently.
2.Application field
These tools can avoid to rise sparking when tools strike,rub or collide with target in explosive atmosphere or flammble vapours and wide used in hazardous environment where flammable and combustible vapors liquids gas dusts are present such as petroleum industry,chemical industry ,power generation ,railroad ,and mining etc.
3.Production method
(1) casting
(2) forging
Solid forging die
Machinery forgings, including freedom of die forgings and precision forging
4.Surface preparation
electrostatic spraying (spray coating)
Essential color (true colors)
Passivation treatment (passivating treatment)
5.material for non sparking safety tools
1. Beryllium bronze explosion-proof tools explosion-proof performance
(a) Standard code: GBEx II C
(b) Hardness: HRC35 above
(c) Tensile strength: 105-120 KGF/mm²
(d) Magnetic: 0
2. Aluminium bronze explosion-proof tools explosion-proof performance
(a) Standard code: GBEx II B
(b) Hardness: HRC25 above
(c) Tensile strength: 75-85 KGF/mm²
3. Different application for different material
1, Materials Al-cu,Be-cu
2, Aluminiumcopper alloy explosionproof tool is synthesis of precious metals, smelting, forging and tool made of the surface yellow. Beryllium copper alloy explosionproof tool for this is a synthesis of military materials and precious metals, made of tool surface is also yellow.
3, Aluminium-copper alloy explosion-proof tool HRC over 25°. Beryllium copper alloy explosion proof tool HRC over 35 °.
4, Tensile strength of aluminiumcopper alloy over 7585kgf/mm.. Beryllium copper alloy tensile strength over 105-120kgf/mm.
5, Aluminiumcopper alloy in ethylene concentration of 7.8% of space, beryllium copper alloy in the hydrogen concentration of 21% of space to ensure safety.
6, Aluminium-copper alloys are more applicable to conditions of pressure equipment and explosion-proof less stringent requirements on the environment (gas stations, small oil depots, etc.). Beryllium copper alloys for refineries to swit.
