Principle and place of using explosion-proof wrench
Explosion-proof live wrench is mainly made of beryllium bronze and filtered aluminum bronze alloy, because copper has relatively good thermal conductivity and does not have the property of carbon at the same time, so that when tools and objects rub or impact, heat will appear in a relatively short time, and the heat will be absorbed or conducted. In addition, because copper itself is relatively soft, it has very good concessions during friction and impact, tiny metal particles will not easily appear, so we can basically not see the appearance of sparks. The explosion-proof wrench made of
aluminum-copper alloy is made of rare metal synthesis, smelting and forging. After the tool is made, the appearance is yellow, the hardness of the working surface is greater than HRC25, and the tensile strength δb>75-85kgf/mm, other technical indicators have reached the level of foreign similar products. Continuous use in the relatively easy-to-burn gas ethylene (concentration 7.8) space ensures safety, and no spark will cause explosion due to impact (collision), friction and drop hammer.
Explosion-proof wrench can be used in many fields such as petroleum refining, petrochemical, oil field, coal mine, gas chemistry, chemical fiber, gunpowder, paint, fertilizer, medicine, etc. Oil wheels and LPG vehicles, aircraft, warehouses dealing in flammable and explosive materials, electrolysis workshops, communication machine assembly workshops, wear-resistant and anti-magnetic places, etc.
