Explosion-proof adjustable wrenches are special hand tools designed for flammable and explosive environments. Their core features are as follows:
1. Definition and Applications
Definition: Explosion-proof adjustable wrenches are similar in appearance to ordinary adjustable wrenches, but are made of spark-free materials and are used for pipeline or equipment maintenance in flammable and explosive places such as petroleum, petrochemicals, natural gas, chemicals, and pharmaceuticals.
Explosion-proof principle: Aluminum bronze or beryllium bronze materials are used to avoid sparks generated by friction between tools and metals, reducing the risk of explosion
Non sparking tools is also called safety tools or explosion proof tools.There are two types of materials.
2. Material and explosion-proof performance
Aluminum bronze,Al-Br,aluminum,nickel,manganese,iron and other metals were added to the high purity electrolytic copper as matrix to form copper-based alloy.
Beryllium copper,Be-Cu,the copper base alloy was forming by adding some metals such as beryllium.
The thermal and electrical conductivity of these two materials are very good,beryllium bronze is non-magnetic and can be used in strong magnetic fields.
3. Structure and Design
Functional Design
It has adjustable jaws, and the opening width can be adjusted by rotating the turbine to adapt to nuts or bolts of different specifications.
It is forbidden to use excessive force or apply force by extending the force arm (such as sleeve) to avoid safety accidents caused by tool breakage.
4. Specifications and Models
Common specifications: expressed as length × maximum opening width, such as 100mm×19mm, 450mm×60mm, etc. The total length covers 100-600mm, meeting the needs of diversified operations.
Non sparking wrench is also named non- sparking spanner.
A non-sparking adjustable wrench is a tool designed for use in environments where sparks could potentially ignite flammable gases or vapors. This type of wrench is made from materials that do not produce sparks when struck against other surfaces, reducing the risk of a fire or explosion.
