Buying Guide
What to check before buying a gas line grounding clamp
Material matters for conductivity and corrosion resistance. Copper alloy and bronze clamps offer good conductivity; bronze and silicon bronze hardware boost durability in outdoor or direct-bury settings.
Pipe compatibility is essential. Most clamps cover 1/2″ to 1″ or 1-1/4″ to 2″ pipes. Confirm your pipe diameter and whether your system uses copper, steel, or another metal.
Wire range compatibility matters too. Ensure the clamp accepts the grounding conductor size you plan to use (commonly #10 to #2 copper or #8 to #2 aluminum).
Installation considerations include included screws, mounting hardware, and whether the clamp is designed for direct burial or surface mounting. Over-tightening can deform pipes; follow manufacturer guidance.
Regulatory alignment helps avoid inspections delays. Look for listings and clear reference to electrical codes or direct-burial suitability.
Material choices at a glance
- Copper alloy clamps: strong conductivity, versatile for copper wires and various pipes.
- Bronze/silicon bronze: excellent corrosion resistance for outdoor or buried applications.
- Bronze hardware: robust for direct burial and long-term durability.
Application scenarios
- Residential: small-diameter gas lines, often 1/2″ to 1″ pipes, ideal for quick, reliable bonding.
- Outdoor or buried systems: clamps rated for direct burial improve safety in soil environments.
- Industrial: bulk packs and bulk clamps help with multiple points of grounding on larger systems.
