help with reg for r1150

[ruffus]

hey guys i just ordered my tank of R1150 for my cascades i am building and i was woundering what other people use as a regulator on there tanks. now i know that the valve on this tank will be a CGA350. now i was told by praxair that i have to have a certin regulator for it. and they are wanting more for the regulator then what i will be paying for the R1150 as i am paying around $400 for 10 pounds for R1150 and they want a little more then that for the regulator. HELP PLEASE ANY ONE :shrug:

here in austria ethylene hast the same thread as other flamable gases (left handed).

edit: thread is W21,80x1/14-LH

[EvoCarlos]

as godmod said the fitting is the same as the flamables fitting

if you had a co2 or another type of bottle reg it could be adopted to fit the above propain stub :)

But do NOT use a regular propane reg.
Look that you buy one, thats made for 200bar.

i should of put this i ment only to use the brass stub from the propain reg and put it on a hi pressure bottle reg :)

[sjg0]

Praxair wont rent you a regulator?

Oh sry, read that over.:)

[ultralo1]

Use a length of cap tube. Just be sure to turn the bottle off after you charging

[teyber]

what fitting is that ultralo? that looks dangerous lol

[ultralo1]

That is a 125 Lbs tank to 1/4 flare fitting on the tank. A piece of 1/4 flared onto the adapter. 20 feet of 0.031 captube brazed in to the 1/4 inch. Then a 1/4 schrader brazed onto the end of the cap tube so that you can attach your hose to.

Not dangerous at all as long as you remember to shut off the tank valve when you are not charging. If you dont you can over pressure your gauges and blow them. This rig has been in use for over 5 years. I do use brute manifolds though.

[teyber]

do you "pulse" it when you charge?

[wdrzal]

Not dangerous at all as long as you remember to shut off the tank valve.

Thats the problem,you can forget,as many guys fried their load tester because they forgot to turn them off.

On another serious note,taking short cuts can be very expensive ,if not deadly. Like if there is a fire and your Insurance company denies your claim.

That cap tube setup doesn't look UL listed to me. It's down right dangerous ,you should remove that post ultralo. People of all ages and experience levels read these forums. IMO you not being responsible even suggesting that. forgetting to close the tank valve will destroy your manifold,rupture your hoses and cause a fire if there is a ignition source.

insurance companies only insure you if your using the "proper" regulator.. even using a hydrogen regulator with ethylene will not be insured i have been told. new house or $750.... (in my quote for a ethylene regulator) :mad:
neither? :(

They are not that expensive Teyber. And just for fun ask how your mom would feel making a house payment for the next 30 years and all she has is a empty lot because of a risk you took and her fire insurance denied the claim.......


But then again,your not making the payment are you Teyber............

Posting potentially Dangerous methods on a open Internet forum is WRONG.

This is not a shortcut. It is an industry accepted practice. It has been used for years not just by me but others in my industry including the manufacturer of commercial cascades.

This site is full of computers that have no cases with exposed power supplies and wiring, ghetto built coolers, people purging with propane while brazing, using none listed refrigerants, striped down ac units submerged in water, homemade wiring harnesses, cutting holes in there house for geo loops, and you believe that the UL listing of an industry accepted practice needs to be brought up? ;)



you should remove that post ultralo. People of all ages and experience levels read these forums.

I will meet you half way, I removed the pic. I had forgotten that there are people of all ages, experience, and maturity levels on here.



IMO you not being responsible even suggesting that. forgetting to close the tank valve will destroy your manifold,rupture your hoses and cause a fire if there is a ignition source.

As far as being responsible, again this is an industry accepted practice. it is used everyday by manufactuers, factory reps, field techs.

It will not destroy quality tools. Hoses usually have a burst pressure of 1000psi or higher, manifolds are higher than that. The burdan tube in the actual gauge itself is the first to go. What refrigerants are in use that exceed this pressure level at room temp?

For the fire hazard, there is only one way to prevent that, Dont Use flammable refrigerants.
Any leak from a system using R290 or ethylene is a potential fire hazard. It seems like those are a popular gases here, instead of non flamable, because it is cheap, readily available, and you dont need an EPA cert. There are plenty of other refrigerants out there that do not pose a fire hazard that can be used.

I would like to think that most people here trying to build cascades and using flamables have already considered the implications of what they are doing. That there is an inherant safety risk involved and that most of them will take the steps to prevent accidents from happening. I would also like to think that the people here who have already started to play with overclocking have some techinical skill.



Posting potentially Dangerous methods on a open Internet forum is WRONG.

Then most all post on this entire board would have to be deleted if you want to remove POTENTIALLY dangerous activities.

[ultralo1]

Check PM

[sdumper]

Good tip ultralo1..

[wdrzal]

Please show me a page from a ASME,RSES,ASHRAE or any other book that promotes the use of a cap tube instead of a regulators as the "industry accepted practice".

BTW: if O.S.H.A. saw that ,you would be cited & fined and maybe even closed until the problem was fixed.

Ps: Please don't try to deflect the dangerous nature of this by citing other dangerous procedures. Remember when users first come to XS cooling,most have no idea how dangerous pressure & chemical energy are.

A good mentor will teach safe practices and always Error on the side of safety.

I have to side with Walt on this one. I often view his safety concerns in the way I would view a bubble-boy but in this case there's too many things that could go wrong. Just spring for a CGA350 regulator or convert a CGA320 regulator. There are some things you can get away with but high pressure and explosive gases aren't one of them. You can get a CGA320 regulator for $50 to $75 and a CGA350 threaded inlet for $5, much better than worrying if the valve you used is going to explode or if you'll accidentally blow up your gauges.

[ultralo1]

How about the manufactuers service manual and course. Will that suffice?

I get inspected once a year. I have been gigged on not having tanks secured, frayed cords, grinder tool rest to far from wheel (1/8 in btw) but never for this regulation device.



Ps: Please don't try to deflect the dangerous nature of this by citing other dangerous procedures. Remember when users first come to XS cooling,most have no idea how dangerous pressure & chemical energy are.

I am not deflecting anything. I am pointing out that you must mention ALL potenially dangerous activity not cherry pick.

I must say that I take that as a slap in the face. I can only guess by your bolding of this and the previous post that you ment it that way.


So who are you? And why should anyone care what you say?

This site is full of computers that have no cases with exposed power supplies and wiring.

There is a difference between exposed line voltage, and 12/5/3.3 vDC lines. If there are exposed main leads, most people make an effort to insulate them. I don't see any problem with exposed computer parts..


ghetto built coolers, people purging with propane while brazing, using none listed refrigerants

And most of that is looked down upon here, especially purging with propane.

striped down ac units submerged in water, homemade wiring harnesses, cutting holes in there house for geo loops, and you believe that the UL listing of an industry accepted practice needs to be brought up? ;)

How does dipping an AC evaporator in water, or making a home made fully insulated wiring harness, or poking a hole in the side of a house compare to running a high pressure gas through gauges and line set that were not designed for it? And if the gauge blows, and the metal blowing out creates a spark?

For how cheap the regulator is, I don't see why you would NOT buy one.

[Sgrios]

Lead Head;3634082']And if the gauge blows, and the metal blowing out creates a spark?

The main concern being a ignition source, however I don't think that would be one. However, I understand where Ultra is coming from. I'd also assume that he's talking about line voltage.

Hmm, if I look at many load testers, people do not really make an effort to insulate properly :down:

[ruffus]

ok guys thanks for all the help but with me i think the right way is the best way as golmer would know as i spent a day picking his brain so that i would do the right thing and i got the proper reg for r1150 and i ended up getting this for $140 shipped to me here in canada

Now that is a very nice regulator :up: A tad bit expensive but it'll do the job quite well.
