Earth clamp for 50mm Earth cable

[Lagentium]

Could anyone recommend a bonding clamp that accepts a 50mm bonding cable please for a 3 inch diameter gas pipe? Welding a flag onto it is sadly not an option, I also have to get a 50mm Earth onto a 40mm water pipe, any idea guys?
Cheers

It is a conductor.

I think the standard 3M range of constant force springs goes above the size you require. CONSTANT FORCE SPRINGS, 3M FORCE SPRINGS, P60, P61, P62, P63, P64, P65 SPRINGS - https://www.cablejoints.co.uk/sub-product-details/3m-scotch-electrical-tapes/constant-force-springs

This kind of clamp may work. There has been a thread on this subject but couldn’t find it!

You can get very large, long adjustable earth clamps. Have some in van somewhere.

If you have a Megger MFT, the IClamp accepts up to 52mm, although isn't great in tight spaces. A Fluke I-Flex may be the answer, available in two sizes.

Presumably, despite the strange replies here, you are looking for a heavy duty bonding clamp or a pipe bonding clamp.
up to 75mm² conductor 3 1/2" pipe
up to 95mm² conductor and 3 1/2" pipe

Note to self to read more thoroughly before replying, was working on earth leakage stuff at the same time and got the wrong end of the stick, or clamp. Haha!

Furse make suitable clamps for lightning conductor connections to large pipes that would serve your purpose nicely.

These are what I have used with 70.0 unfortunately I have no idea where they came from, made by Kleinhuis. The conductor connected is 50.0 Looks very similar to RBs pic.

In my post the upper picture is a link to the niglon version of westward10s clamp, the lower picture is a link to the Furse section of ABB and the range of clamps.

Showing my ignorance again, but those look like big jubilee clips...
I love 'em! Used to use them to clamp the asbestos rope round the exhaust on our powerboat...odd how the rope steamed so much when new and the engine was running! Still, you could happily place your hand on the rope covering and no burning...
not sure how my lungs are though...
