Earth bond clamp for oil pipe

[suffolkspark]

I still di t get why an earth clamp wont fit? Take a pic im intrigued, ps dont forget to affix bonding label to your clamp

Hi Suffolk
Standard clamps I have seen either have a sort of box section bit in the clamp which would wobble about on top of the pipe or have a 'U' shaped but with the clamp which is too big and straddles the pipe and band can't go tight enough. Honest. I've tried. ...

wind a bit of bare 6.0mm round the pipe. solder in place. sleeve the tail after .

Now that is a bloody good idea
Hats off to you

Some care required if you are planning to solder a heating oil supply line. From memory, soldering needs about 200C and the auto ignition point of heating oil is about that too. Just saying ...

1.do it when there's no oil in the pipe

2. clamp heat sinks on pipe to prevent the oil overheating. it needs to vaporise to ignite.

The oil will not ignite unless it reaches temperature where it vaporizes allowing it to mix with oxygen, liquids do not burn it will however act as a heat sink removing the temperature from the pipe.

That's right, these fuels won't burn without air. It's my understanding the vapour point of heating oil is significantly below the melting point of solder. Again, just saying ...

maybe an experiment.... a whole new concept of the bang test.

The flash point of heating oil depending on the type will be approximately half 200°C.

but how can it vaporise when it's confined in the tube?

It can expand but even if it did manage to reach flash point and vaporize it would still need a sufficient heat source to ignite. Highly unlikely but most things are possible especially if it started spraying from a joint due to the expansion. I personally would not try it.

I'm not saying death and destruction will ensue, but I would "prudently avoid the known risk" of applying heat to a fuel line.

I've tried. Just too big for this one.

I've never had an issue getting standard earth clamps to fit a 10mm oil pipe.

I've used a length of 1.0mm bare copper before. Bind it in tight turns around the pipe and back on itself if necessary. Clamp over that, done right it'll fit tight.
