They are mainly used in hazardous environment where flammable and combustible vapors liquilds gas dusts are present, such as petroleum industy,chemical industry, power generation,railroad,and mining ects.These tools can avoid to rise sparking when tools strike,rub or collide with target in explosive atmosphere. There is two kinds of material, Beryllium Copper alloy and Aluminium Bronze. Special tools. 45# steel, 40Cr. Non-magnetic tools. Material Stainless steel 304 1)Good resistance to acids and alkalis corrosion 2) Mainly used in medical apparatus and instruments, food industry ect. 3) Weakness: Low strength, low hardness. HRC<10° Terrace Measuring Tools. 1. Machinery production 2. Installation of the machine 3. Lineation , marking out and measuring 4. Welding 5. Surface plates 1.What is a "non-sparking" tool? "Nonsparking", "spark reduced", "sparkresistant" or "sparkproof" tools are names given to tools made of metals such as brass, bronze, Monel metal (coppernickel alloy), copperaluminum alloys (aluminum bronze), or copper-beryllium alloys (beryllium bronze).
Commonly used hand tools are often manufactured of steel alloys. Preferred "nonsparking" 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.Explosion-proof tools technology parameters 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 switch gas stations, gas production plants, drilling crew and so on.
