Explosion-proof reducer adapter Material: Aluminum bronze, beryllium bronze Aluminum bronze material, working surface hardness above HRC25°, tensile strength not less than δ b 75-85kgf/mm2, national Class IIB product, operates in 7.8% concentration ethylene gas; Beryllium bronze material, working surface hardness above HRC35°, tensile strength δ b>105-120kgf/mm2, national Class IIC product, operates in 21% concentration hydrogen gas without gas; Beryllium copper alloy explosion-proof tools also have special anti-magnetic function, can be used normally in magnetic field working environments. The above two materials of explosion-proof tools can effectively prevent the combustibility generated by friction and impact between the tool and the workpiece, ensuring national property and personal safety! Applicable places: Petroleum, chemical, mining, anti-terrorism, anti-magnetic field, coal mine, gas extraction, oil and gas pipelines, power generation, metallurgy,
