So the meter outside my house reduces the pressure? I thought the

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
20mbar.

http://www.gasinfo.uk.com/distribution_page.htm

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.

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


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?


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

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.


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


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.


I didn't know that. I've never used a stove in cold temperatures. So anyone camping in winter uses propane?

Strangely, I find the common sense I was born with answers that question
pretty conclusively. There could be no circumstances in which excess
gas needed to be discharged randomly in the middle of the countryside.
If it were necessary it would be done at the origin or termination of
the line, and it is equally unlikely that any leak of gas would be
deliberately ignited. There can be no doubt about this.

Well that's what I thought, and was made clear in my original post.

But.... I've seen them. They are not poles with a bright orange marker on top, they have a mechanism inside, they clearly do something with the gas.

You lack perspective. I hesitate to suggest that you are quite mad, but
it fits the facts. "Hardly anything worse in the world" than people who
encourage trolls on Usenet.[1] What a pampered life you lead! It

Yeah, the pipeline company never bothers to measure how much product
enters and leaves the pipeline, so they'd never notice such a crime.

I'm surprised they don't say on them they're restricted to warm days. Cold days are when you're more likely to use them!

I could understand them not mentioning it if the limit was below -20C or something. But someone said even 6C causes problems.

The main pipelines run at some insane pressures & they don't vent. The
estimate for the SPL at 100m if our pipeline was breached is 140dB.

The high pressure network represents a significant proportion of the
country's stored gas.

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).

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.


The main pipelines run at some insane pressures & they don't vent. The
estimate for the SPL at 100m if our pipeline was breached is 140dB.

The high pressure network represents a significant proportion of the
country's stored gas.


But is it usable? Say the input failed for a while, could we use up what's in the high pressure pipes? Could they transfer it all to low pressure at the normal rate?

Why do you think gasometers have nearly all disappeared? Our reserves are
now stored in the pipeline.

I thought it was piped in from the north sea, Russia, whatever.

P.S. why did they always stink? Well the ones on Dock Street, Dundee did anyway.

Our reserves are now stored in the pipeline.


So presumably this pipeline is variable pressure?

https://www.nationalgridgas.com/balancing/nts-linepack

" Methodology

We determine NTS linepack by calculating the volume of gas within
the NTS pipelines, using a network model and instantaneous
measurements. The model contains a database of NTS pipeline
diameters and lengths, updated as required to accommodate changes
to the network.

The NTS is divided into pipeline sections, and the volume of gas
within each section is determined by multiplication of the pipe
free volume by the ratio of the gas density at actual conditions
to the gas density at standard temperature and pressure.

The actual gas density is computed from a standard equation of
state applying pressure, temperature and specific gravity data.
The pressure is derived from telemetered measurements at the
beginning and end of the pipeline section, and an average network
gas temperature is applied. The specific gravity is determined
from telemetered measurements at NTS entry and exit points
according to a fixed mapping arrangement. The network model then
summates the calculated volume of gas for each pipeline section
to compute total NTS linepack.

The opening NTS linepack for a gas day, which is equivalent to
the closing NTS linepack for the preceding gas day, will be the
volume calculated by the network model as close to the start of
the gas day as possible."

Why did we used to need gasometers? Surely a high pressure pipeline isn't something really technologically advanced?

Because of the way gas was generated then, locally, instead
coming out of the ground hundreds of miles away.

Surely a high pressure pipeline isn't something really technologically
advanced?


Correct. bit not necessary when the gas is generated locally.
