Explosion-proof arched scraper is a copper alloy non sparking hand tool designed for flammable and explosive environments.The scraper is for rust removal.
1. Core features of the non sparking scraper
Explosion-proof principle
Made of beryllium bronze (Be-Cu) or aluminum bronze (Al-Cu), the high thermal conductivity and low friction characteristics of the material prevent sparks during operation and have corrosion resistance.
Beryllium bronze products have anti-magnetic properties and are suitable for strong magnetic fields or chemical corrosion environments. Beryllium bronze has a higher explosion-proof grade
Applicable places
Repair and maintenance of explosive and high-risk areas such as petrochemical plants, natural gas filling stations, coal mines, and flammable gas transport vehicle maintenance stations.
2. Specifications of the non sparking scraper are shown in the table above.
3. Structural design of the non sparking scraper
Arched shovel: The shovel head is arc-shaped, which is convenient for cleaning rust on curved surfaces.
Double-head scraper: Different blade shapes (flat/pointed) at both ends to meet a variety of rust removal needs.
Handle-mounted type: The wooden handle or fiberglass handle can be replaced to enhance operational flexibility.
️ IV. Use and Maintenance of the non sparking scraper
Operation Taboo: Overload scraping or hammering (non-special striking tools) is prohibited.
Regular inspection: Severely worn scraper blades need to be replaced in time to avoid brute force operation.
Non-sparking scraper can be also used in marine enginerring,the material is aluminum bronze or beryllium copper.
Performance
