Explosion proof listening needle

Explosion proof listening needle:

Listening needle,also known as listening stick,is used to diagnose engine malfunctions,boiler leaks,etc.

The listening needle is an ideal tool for checking machine and equipment malfunctions,valve leaks,and underground water seepage sounds in coal mines.By using the principle of conduction,the problem area can be accurately identified.

Tingzhen is an ideal inspection tool for industries such as petroleum,chemical,petrochemical,power generation,metallurgy,mining,coal mining,and machinery.

Listening needle specifications(mm):300,400,500,600,700,800,900,1000,1200,1500.

Tools are divided into beryllium bronze and aluminum bronze.Beryllium bronze alloy and aluminum bronze alloy,due to their material ratio,do not produce sparks during impact or friction,and are suitable for use in explosive,flammable gases,strong magnetic and corrosive environments.The BeA-20C alloy withstands an impact energy of 561IJ in air containing 30%oxygen or 6.5-10%methane oxygen,with 20 impacts without sparking or combustion,thus avoiding the danger of detonation in flammable gas environments.
