Hi-viz poles to allow the chopper to follow the pipeline route easily.

They're not just markers, I'm sure they can actually let off gas.

They are simple makers for the helicopter that checks the pipeline to
follow with its airborne leak checker. One of the high pressure
pipelines runs close to me. They also mark the no dig zone at the
roadside (permission required from the pipeline owner Ineos or Shell).

That seems unfair; after a boring day mashing up roadside culverts and
the occasional fibre duct, a high pressure gas pipeline would be quite

My local council once dug through a gas pipeline in my street. Unfortunately it didn't catch light and blow one of the dimwits to kingdom come, so there was just a smell of gas, some workmen running about hurriedly making phonecalls, and no gas for the afternoon.

What I like is when snowploughs destroy those stupid ****ing bollards on chicanes, as they can't see them in deep snow. I removed one myself once when I had an old Range Rover. They're plastic and smash up easily.

Are you sure? I looked at one once and I'm sure it had some kind of valve in it to let gas out. When I asked someone at the time, I was told that if it had let off pressure and ignited it, the bright orange lid would have been blackened, signifying there had been a problem.

A) I didn't know it was that high a pressure, in fact I thought it might just be the final house pressure.

B) It's better to let it off in a flame (and they're usually on quiet B roads) than to let it build up and cause an explosion.

Yes one round the back of my l
place. They had to fiddle with the pressure though as everyone heard a

Agreed. Perhaps it's some kind of game the government is playing with us, to see if they can get people to be polite and let others go first (like with the single track roads in the NW of Scotland).

But in reality, you get BMW drivers assuming they have a better car so can go first. And people like me who can't stand arseholes with lights on during the day, and assume they must be flashing to let me go first :-)

https://www.sabic.com/en/about/ehss/sabic-uk-pipelines

I did wonder how they could distribute all that gas at 1.1 bar. I guess there's a lot of complicated valves somewhere to change the "voltage" as it were? Do they ever fail and put high pressure into the final piping? I dread to think what would happen if the "insane" pressure got into your boiler.

There are pressure reducing meters at pretty much every point-of-use which
reduce the line pressure to a pressure compatible with standard appliances;
you may notice that some meters have a much smaller inlet pipe than the outlet
pipe (e.g. commercial premises) due to the need to for more volume at the
lower pressure.

So the meter outside my house reduces the pressure? I thought the pressure was lowered for the whole street, like a substation reduces the electricity to 240V.

I had noticed on older houses there's some kind of valve seperate from the meter (often exposed to the outdoor weather!), presumably nowadays it's inside the meter.

Your meter has a regulator that drops from an already lowish pressure to

Wow, 20mbar is damn low, I'm surprised that has the desire to move along the pipe.

How do things like camping stoves work? I assume the pressure inside a butane cannister is much higher than that, and I don't think they have pressure reducers.

How do things like camping stoves work? I assume the pressure inside a
butane cannister is much higher than that, and I don't think they have
pressure reducers.

They do have pressure reducers for the bigger stuff like barbeques.

Your meter has a regulator that drops from an already lowish pressure to
20mbar.

Wow, 20mbar is damn low, I'm surprised that has the desire to move along
the pipe.

I presume that the needle valve and feed to it is sized to be very
restrictive for the simple screw on burners.

The bigger ones fed by hose from a Calor cyclinder or the like have
28mBar regulators for butane or 37 mBar ones for propane. The different
pressures allowing for the different calorific values of the two gases
when using the same size jets, so allowing interchanging bottles
depending upon the ambient temperatures. Butane won't gas off from the
liquid on a cold day.

With high flows, such as a water heater (my parents' one needed a
regulator capable of 4kg of per hour), the boiling off of the gas can
cool the bottle too much and reduce gassing, so even in the summer, they
had to use two butane bottles in parallel or a single propane one.

For example, I have a twin burner (Tilly) stove. It's fed from a butane cannister. Since I could operate one or both burners at different rates, there can't be a limiter anywhere that could work unless it's clever enough to adjust pressure independant of flow rate. Perhaps the pressure is quite high, but the taps to control the burners are what restricts it?

I wasn't aware of that, so I can't use a butane camping stove in winter?

Gasoline isn't a word used in the UK. Oil is refined to petrol. Gas is.... well a gas. Like propane or butane. If I have a car which runs on gas, it means I've converted it to take LPG (propane).

On that note, I heard once (not sure if this is true), that when refining oil to petrol, there's lots and lots of unused propane produced which they just burn off! One of the reasons LPG is so cheap apparently. Mind you I have noticed our local refinery is no longer spouting a huge wasteful flame on top, so perhaps they found a more sensible use for it.

whereas our "petrol" is thought to be short for "refined petroleum".

Which is exactly what it is.

Or a separate restrictors before each valve - probably just the valve
design though.

Basically correct. You may get away with it, but when temperatures are
down to about 4°C, the cylinder cools a little further as the gas is
used and it gets the bottle too cold to boil any more gas off. It is not
actually a sudden cut-off, it is a reduction in the rate of boiling and
so the gas flow is too low for the burners.
