Natural Gas Line

[irregardless]

Quick question hoping someone on here can give me a straight answer.

I've talked to 3 professionals about running natural gas line from a NG well to my house and garage...

We're looking at a hell of a run w/ it. I haven't actually measured but it's 1500' MINIMUM and possibly 2000'.


I'm wondering if a single 1" pipe would be enough to supply both the house and the garage w/ enough gas if we up the pressure (well was at 125+ psi last time I looked at the gauge, so that wouldn't be an issue). The house has geothermal heat, electric water heater, electric stove, and only a gas fireplace currently.

Once in place we'll be using the fireplace for heat as well as adding a second gas heater/fireplace in the basement for the kids. Once the water heater takes a crapp, we'll switch it over to NG as well, same for the stove, clothes dryer, etc, etc...

Garage will only have a NG heater and POSSIBLY a stove for canning and the like in the summer to keep the heat out of the house.



And because no pics, here's of a pic of a pic from FB:

tl;dr=
If running NG line for a house and garage over 1/4 mile can I get by with a single 1" pipe or do I need to run 2x1" pipes?

Size of the pipe will depend on pressure from the well, you would need to have a multi stage regulator setup I would guess, I've never seen a house connected to an onsite gas well around here.

You need somebody who designs the delivery side of nat gas systems to plan this out.

You will need a gas pipeline engineer to help with the design.... But at 125 psi 1" will probably be good.

You will need multiple regulators to reduce the pressure at your point of use (down to ounces of psi) and your design should also include pressure relief valves for over pressure protection... And an oderant injection system so leaks can be detected by smell.

One last point is... Gas from a well has not been processed in a plant, so may contain other products such as ethane, propane, butane, h2s, and other heavy by products. If you don't know... You need to have it analyzed.

I think gas pipe is rated max of 80 psi. I would think you could get by with probably lease then that using 1" pipe. You would have to call a gas fitter to do the calc on a run that long.

Here is a calc.

vonhef has a lot of valid points. being a Hvac tech myself it does not sound feasible w/o a lot of engineering and safety procedures

It sounds like you are going to have a pro do the work and just want a sanity check.

If so the 1" line is good for any sane use (less than 1 psig loss @ 400,000 btus/hour. assume ~ 1000 btu/ft.3 and 125 psig supply regulated at the house).

If you have any specific questions pm me, I have a gas well and did most of the work myself.

But in any case your neighbors are a very good source information, suppliers and installers.

I have a similar set up here. 1" gas line approx. 1/4 mile from the well to the house. You'll need a "field" regulator at the well to reduce the pressure in the line. I also have a dryer before the field regulator. I have a "house" regulator at the garage to reduce it to useable pressure there, and the same at the house. I heat the garage with a 250,000 btu Trane, and my house is total ng heat, water heater, cook stove, clothes dryer. I don't have any special cleaner or scrubber, and the gas company/well tenders take care of the odorizers. I hope this helps.

Exactly. I'm all for DIY on most things, but this is well out of my comfort zone. I may trench the pipe in for the pros, but they can do all of the connections and hook ups.

I like explosions as much as the next guy, but not anywhere near my family.


If anyone has any suggestions for any specific safety equipment, by all means post them.

In the OLD oilfields of Pennsylvania and New York state it was not uncommon to pipe oilfield gas to the house!
Most times it got there at 5 to 10 psi, then regulated down from there.
Most of those old set ups didn't have "odorizers" nor did they blow up!
Houses were not air tight like they are now.
Common Sense was used.

inch upto the house will be ok at that pressure then you will need a multi stage upso opso regulator to bring it down to the correct inches of working pressurefor the appliances , the high pressure wont be allowed inside the building so will have to mount the regulator outside . upso opso = under pressure shut off over pressur shut off

 

[Rookie2]

not a problem, Just find or ask the driller for the names of their well service contractors, they can trench it in in a day plus joint weld .

 

[plumbstupid]

I think you will probaly be installing a regulator at the well to reduce the pressure to 5 psi. Then run a 1" line to the house and install another regulator at the house to get you down to ounces.
