propane piping

[mrjigger]

I need to hook up a propane oven/range and heater in my fish house. I plan on doing most of it with the black rubber hose.

But would like to do a couple small sections with rigid piping.

Preferably threaded fittings.

Can I use that black or galvanized looking piping with threaded fittings? If so, what is the best way to seal the fittings?

thanks.

Black pipe would be the preferred type to use. Using the improper galvanized pipe can result in problems caused by flaking of the galvanizing plugging orfices in your propane accessories. Use a good quality of TFE Teflon paste, or a roll of Teflon tape. Pressurize and check connections, especially those that will be inaccessible after the project is finished.

Black iron pipe as stated and use the teflon tape rated for gas lines. It's yellow in color or use regular pipe dope. EZ to do, just use the spray on leak detector to check all your fittings for tightness before use.

How about copper tubing?

"especially those that will be inaccessible after the project is finished"

I wouldn't have any joint or fitting that is not accessible. Fish houses get to much abuse to think the joints will hold forever.

my dads house house is done 100% in soft copper and compression fittings. 3 gas lights and the heater

Sorry but compression fittings are a no-go on gas lines.

You gotta use flare fittings with soft copper.

I hope you mean flared fittings if you have used compresion fittings that are made for water lines I fear for your saftey because they will most likely start to leak especially with the abuse of a fish house I would recommend removing them asap.

Thanks for all the help. I am using flared.

Do you have to use tape on the flared fittings?

The old timer at the hardware store said I didn't have to use it on flared. He said the flare is what seals the fitting.

[Archerysniper]

If you use anything just you pipe dope and only on the threads and try to keep it out of the flared portion. And the old timer is right as usual.

Just use pipe dope not tape. Not needed on flared.

[JeffB]

Another tip is to use a spray bottle of soapy H2O to check for leaks at the fittings. Its a good idea to check everything good at the start of each season.

Troy,

I would think either type of pipe would work. If you want to use soft copper I have some leftover from my garage heater install a few years back if you need some. It is the thicker gas approved stuff. I also have the flaring tool if you need to borrow it. According to my wifes uncle who does gas lines for a living he said not to use any dope or tape on flared. On Black pipe use Harveys pipe dope in the yellow bottle it is far superior to any tape. If you need some help I could buzz over and help ya.

To Clarify Either Threaded Black pipe or flexible copper. Galv. is for water only.

[Archerysniper]

Galvanized pipe is approved and used for gas piping the reason for the galvanizing is to keep the pipe from deteriating/rusting and is code that gas lines run outside be copper type L or K galvanized or black pipe must be painted to prevent corossion.

Though it is approved, the other choices are better.
