Xinda Non Sparking Ball Pein Hammers Copper Alloy and Explosion Proof Hand Tools Factory
Non sparking Ball pein Hammers Copper alloy and Explosion proof Hand Tools Factory
The non sparking hammer is specially designed for environments prone to fire and explosion (such as oil, chemical, and mining industries). Its core feature is that it uses copper alloy materials (such as beryllium bronze or aluminum bronze) to prevent mechanical sparks from being generated through friction or impact during operation, thereby preventing explosion accidents.
Material Requirements: According to the national standard (GB 10693-1989), it is mandatory to use beryllium bronze (hardness ≥ HRC 35) or aluminum bronze (hardness ≥ HRC 25), and undergo drop test (21% hydrogen environment) and friction spark-free test.
Explosion-proof Rating: Beryllium bronze is suitable for environment of Class II C (hydrogen concentration ≤ 21%), and aluminum bronze is suitable for environment of Class II B (ethylene concentration ≤ 7.8%).
