Non-Sparking Tools

See Non-sparking tools EGAMASTER, S.A. Non-Sparking Tools are the best alternative for non-sparking application purposes in potentially explosive enviroments. All tools are forged after casting to achieve the best quality in the market, both in mechanical properties and attractive finishing. We incorporate to our non-sparking tools all our knowledge of decades designing and manufacturing hand tools, making the most ergonomic, easy-to-be-used and nicest design for them.


All EGA Master Tools are manufactured according to the strict control of ISO 9001-200, certified by the most prestigious institution for hand tool manufacturing, TÜV-Rheindland/Germany.

PROPERTIES AND FEATURES

Property

Aplication or Benefits

Non-sparking

Appropiate for explosive potential enviroments .

Non-magnetic safety

Essential for equipments that require complete non-magnetic safety

Corrosion resistant

Specially well suited for applications in corrosive enviroments like encountered in marine works or fire-fighting applications.

Forged after casting

Provides higher mechanical properties and better finishing.

Ergonomic designs

The use of bi-material anti-slippery handles, dipping anti-slippery, totally ergononomic desings make operations easier, more confortable and master.

CAUTION: These tools are not clasified as anti-static because they do conduct electricity. Do not use high copper content tools in direct contact with acetylene due to the possible formation of explosive acetylide, specially in presence of moisture.


DIFFERENCES AND HOW TO MAKE THE CORRECT CHOICE

Concept

Cu-Be

Al- Br

Hardness

35-40HRc

25-30HRc

Magnetism

Non ferrous substance in the composition makes it safer when non-magnetic applications are required.

Minimun ferrous components makes them not 100% non-magnetic, although its low magnetism make it appropiate for non critical non-magnetic applications.

Durability

Much higher due to the higher hardness and tensile strength. hogher efforts can be made.

Not as much as Cu-Be.

Price

Higher price due to the special raw material used

Around 30% lower price.

Tools made of Cu-Be alloy can be used in all groups (I, IIA, IIB, IIC) in a safe way, always respecting the maximun surface temperature allowed, except with acetylene that can create explosive acetylite gases.

Tools made of Al-Bronze alloy can be used in a safe way, allways respecting the maximun surface temperature allowed, except for the IIC group (Hydrogen, gas of water, acetylene, bisulphide of carbon, Ethyl nitrate) .


SAFE WORK IN ACETHYLENE ENVIROMENTS

Items with copper compositions higher than 65% should not be used in acetylene enviroments. Both aluminium-bronze and copper-berylium allows do have higher copper compositions than 65%. Reason is not that copper-berylium can create a spark with the enough energy to create the ignition of acetylene, but that copper can react with acetylene creating highly explosive acetylates. For this reason, copper-beryllium or aluminium-bronze alloys should not be used in acetylene enviroments. EGMASTER, S.A is working in a newly developed non-sparking alloy that may be 100% safe to be employed in acetylene enviroments. If that is your situation, please contact us to be informed about the availability.

INSTRUCTIONS FOR USE AND WARRANTY:

• Non-sparking Tools cannot reach the hardnes of conventional tools. For this reason the use of Non-Sparking Tools has to be carried out with special care, avoiding overstraining, heating, etc

•  To avoid damage being caused to both tool and fastener, it is necessary to always ensure that the correctly sized spanner/wrench/screwdriver is selected.  Due to the reduced strength and wear resistance of Non-Sparking Alloys selecting the correctly sized tool becomes essential to avoid premature wear and early deterioration of the tool.

•  The use of   Non-Sparking Tools must not be the only preventive measure in areas which the items are designed for.  Other items, clothes or present material must also be adequate for non-sparking purposes.
