Principle and place of using explosion-proof wrench
10 Jul,2024
Explosion-proof wrenches are mainly made of copper alloy, because copper has relatively good thermal conductivity and does not have the properties of carbon, which makes heat appear in a relatively short period of time when tools and objects are rubbed or impacted. The heat is absorbed or conducted. In addition, because copper itself is relatively soft, it has very good concessionality during friction and impact, will not easily appear tiny metal particles, so we basically can not see the emergence of sparks, so the explosion-proof wrench will be called non-spark wrench.
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 face is greater than HRC25, the tensile strength δb>75-85kgf/mm, and other technical indexes have reached the higher level of similar foreign 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 petroleum refining and petrochemical, oil fields, coal mines, gas chemistry, chemical fiber, gunpowder, paint, fertilizer, medicine and many other fields. 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.
