propane regulation

Delbert.. When you say 'blocked line pressure' are you referring to a decrease in line diameter at some point coming from the tank???

Blocked line pressure is what the dial reads when no gas is flowing. With mine when I have the shut-off valve closed, reads 7 psi, and when I have it open(using the forge) it reads 5-5 1/2 psi, depending on what I'm doing. Both these numbers are blocked line pressure. I am drawing off 1 1/2 to 2 pounds of pressure.

Regardless of what your forge requires, it is VERY DANGEROUS to run tank pressure into a dwelling, or any confined space for that matter. Keep in mind, at 70 degrees ambient outdoor temperature, your tank pressure is well over 100 lbs. Any competent inspector would have a coronary if he saw you guys at work! Please, please, put a regulator on as close to the tank as possible.
 
Brandon... I'm not sure if you read the entire thread or not, but I had the propane company install the outside components AND and an inspector look at my set up which is what started this whole thread. The installation guy was fine with running without a reg. Good idea? I guess not based on everybody's response. The inspector's opinion was that my set up is safe but local code requires a regulator and he gave me some options. None of the options are running without a regulator on the tank. The purpose of the thread was to find out what kind of regulator or if I simply have to re-think my entire system. The question has pretty much been answered.
 
Unless I read the entire thread in my sleep, there are folks that have posted that THEY are running tank pressure into a confined space. OP or not, it is dangerous and a serious code violation. Blow your house up (not just you Mossanimal, anybody) in a gas related accident, then see what your insurance adjustor says when he sees your unregulated propane going into what is left of your garage.

I do this everyday in a non knife related capacity. Laws and regulations are in place for a reason. More often than not it's a good one.
 
I know little about the requirements for forging, but if you're worried about lower heat levels could a (extra) layer of insulation (firebrick, etc) around your furnace help keep the temperature up?
 
That's why I'm getting a regulator. I've already arranged it. I had a specific question I wanted answered and it was answered... so no need to preach okay... I think the point has already been made. Again... there was no intent to run without one after the inspection. I wanted to know if I could continue running my forge with the changes that are going to happen.
 
Mossanimal, I apologize if I de-railed your thread, or if I offended you in any way. That was certainly not my intent. I will save the DIY advice for the DIY forums.
 
You guys had me worried, so I went and checked my shop tank. I must have had a brain fart, it does have a regulator, a big red one. I remember when the guys installed it (over 10 years ago), saying I would have something less than10 lbs of pressure and I said "oh no I wont" :) So they put in a high pressure reg at the tank and a low pressure reg where it enters the shop at my hot water heater. So, never mind me, my memory sucks...
 
no problem Brandon... it just rubbed me the wrong way having somebody coming in and saying 'don't do that' when there was plenty of good advice already thrown out. Anyway.. I got what I needed and am making the adjustment.
 
I run tank pressure from my 100 gallon tank into my shop. I need to put a 10bar (145 psi) regulator onto it to make it comply with all the regulations though.

For my forced air welding forge I run 2-3 psi. I'm able to heat 1.5"x.1.75"x6" billets with ease so if you switch to forced air you will be fine with even 5 psi.
 
This all has a lot to do with the piping from the tank. Plain black iron cannot handle tank pressure safely. It might (mine did... for months... until the propane company safety guy saw it and explained howcum it is dangerous), and then again, it might not. If it doesn't, somebody will have a problem, a big one, you, if you are still around to have it, but somebody. This is not preaching, not my opinion, not open to anyone's subjective personal decision, just a fact, not aimed at anyone in particular, just contributing what I know from 36 years of running gas lines around my place. I know guys ignore this alla time. ¡Vaya con Dios!
