What is the role of the electrostatic grounding device of the gasoline transfer tank

2025-06-13 Leave a message

Electrostatic Grounding Device for Gasoline Transfer Tanks

The electrostatic grounding device is a core safety component that prevents dangerous static electricity accumulation during gasoline transportation.

1. Preventing Explosions from Static Electricity

  • Gasoline generates static electricity through friction with tank walls during transport (flow/shaking)
  • Accumulated static can create sparks that ignite gasoline vapors (explosion limit: 1.3%-6%)
  • Grounding device maintains safe potential (<30 volts) by directing charge to earth

2. Balancing Potential Differences

  • Vehicles accumulate static from air friction and tire-ground contact
  • Grounding creates equipotential between tank, vehicle, and piping
  • Eliminates sparks from metal contact or human touch

Regulatory Compliance

Mandatory requirements under API standards (US) and GB/T 18564 (China):

  • Regular testing (ground resistance <10Ω)
  • Safety inspections for grounding effectiveness
  • Penalties for non-compliance (fines, operational suspension)

3. Equipment and Personnel Protection

  • Prevents damage to electronic components (sensors, controllers)
  • Eliminates static shocks to operators
  • Essential for operational safety during fueling/transfer

Safety Warning

Proper grounding is critical - failure can lead to:

  • Catastrophic explosions from static discharge
  • Equipment failure and operational downtime
  • Regulatory violations and liability issues
