Wrenches
Spanners (explosion-proof) are a tool that can safely tighten and remove nuts and bolts even at work sites where there is a danger of open flames. It is made of non-ignitable materials such as aluminum bronze, nickel aluminum copper alloy, etc., so that even if it is subjected to shock or friction, sparks will not dissipate. Therefore, it is suitable for use in chemical factories, paint factories, gas work sites, thermal power plants, etc., which handle explosion hazards, flammable / flammable substances. There are many types of wrenches (explosion-proof), including double-ended wrenches, single-ended wrenches, combination wrenches, etc. Also, due to the large size, it is necessary to select the most appropriate wrench (explosion-proof) for the application.
