Material classification and correct use management methods of explosion-proof tools

all kinds of wrenches of explosion-proof hand tools have different rated strengths. It is strictly forbidden to add casing overload to make all experimental machines reach the accuracy of 0.5 level. There is no problem. It is not allowed to knock with (except for knocking wrenches), so as not to cause overload fracture and deformation, which will affect normal use. All kinds of wrenches of explosion-proof hand tools have different rated strengths. It is strictly forbidden to add casing for overload use (except for percussion wrenches). Percussion is not allowed, so as not to cause overload fracture and deformation, which will affect normal use

explosion proof tools are mainly made of aluminum bronze alloy and beryllium bronze alloy

explosion proof tools made of aluminum bronze alloy:

are national class II class B products, and do not detonate gas when working in an ethylene gas environment with a concentration of 7.8%

Explosion proof tools made of beryllium bronze alloy:

are national class II class C products, and do not detonate gas when working in a hydrogen gas environment with a concentration of 21%. Beryllium bronze explosion-proof tools have no magnetism (magnetism is 0), so they are also ideal tools for operation in magnetic field environment. Foreign customers call them antimagnetic tools

in the process of using explosion-proof tools, their varieties and specifications should be reasonably selected according to needs, and it is not allowed to replace large ones with small ones. It should also be pointed out that when using adjustable wrenches, pipe wrenches and solid wrenches, attention should be paid to the requirements of the direction of force, and no arbitrary reverse force is allowed. When using cutting-edge tools and equipment to regularly carry out protective tools, the hardness of the workpiece itself should be measured first. If the hardness is close to the hardness of the tool, careful operation should be carried out, and it is forbidden to use when the hardness is higher than the hardness of the tool. When the workpiece is mechanically tightened and semi permanent, the data will be provided to predict the results of these innovations, or because of long-term corrosion, and no other measures are taken before using the manual tool, it should be prohibited to use, so as not to damage the tool

management method of explosion-proof tools

after the use of explosion-proof tools, they should be wiped in time. If they are not used for a long time, they should be coated with a layer of oil on the surface of explosion-proof tools or stored in packaging bags or inward with anti-corrosion methods. Some explosion-proof tools are worn and incomplete after use, especially the explosion-proof tools with blades, or seriously damaged after the final acceptance of the equipment, so they should not be used anymore
