Steel Propress

bob_50

make steel fittings for propress. They could be made to fit E.M.T. that way nobody would have to make special tubing. With the cost of copper so high it could save lots of bucks. It would be less labor intensive than switching back to threaded sch40.

They already do

The REMS catalog shows steel, brass, copper, stainless steel applications.

I've heard that fitting and tool is used for hydraulic piping, compressed air, various gases potable water, boiler applications, etc.

I think a pressure rated thin walled steel, maybe schedule 10 or 20 would be a good option for hydronic systems.

I've seen sch 20 and lighter roll groved in fire protection work before. I would think the press fitting would perform as well or better?

I imagine it has to do with the cost of listing the system to the many listings required in this country. And the amount of market available to support that cost.

Hot Rod's right !

I have the proof ! Here's a pic of the stainless Propress system . They are using it extensively for medical and food industries in the EU.

P.S. This photo was named over a year ago. Chris

Victaulic makes Pressfit fittings for steel. Not compatable with ProPress though.

This idea's time has come

I love copper, but with prices the way they are we need more options. I was just looking at my code book, and it lists ASTM A 53, and A 106 as standards or steel pipe for use in hydronic systems. Well I guess I will have to look up those ASTM # to find out what minimum Schedule we can use for hydronic pipng...

Fire Truck in the living room

maybe someone still has the thread where a guy was asking how much thermal gain he could be storing in his living room...*~/;) the only noticably variable was the "rolling stock" his entire boiler was done in press stainless. what a beautiful sight

you would have loved the challange Brad:) you could have had two ,...three calculators "smokin"

Rumor has it

Rumor has it that Viega, who already has this stuff in Europe, is contemplating bringing their line of Stainless PP fittings over here. Time frame unknown but I'll bet that a bunch of us requesting these fittings coupled with the price of copper would get them here quicker.

I can see it all in my minds eye right now. Near boiler piping all stainless with PAP or Pex running out to the zones. How sweet would that be. As far as I'm concerned, it cant happen soon enough. Has anyone else noticed the quality of the copper tube these days seems to be diminshing rapidly?

new every day. That's amazing Victaulic has a system for 3/4" to 2" sch 5 steel pipe.

ASTM #'s

Cosmo,

I found this chart handy for quick reference. Not all-inclusive but when the big book is in the office and if anyone could find it.... works in a pinch.

Thanks, Weez

Batteries gave out before I got the answer Would have loved to see that installation! But Hot Rod gave me a preview. That wet dream installation was, well, unbelievable...!

Brad,

That photo was taken at the Attendorn, Viega factory/shipping center.I believe that was in the training center.

On a job site we visited, they were running it in all the hidden spaces (walls)for domestic water, and then had manifolds for each apartment. Very slick, to say the least. Chris

Thanks, Chris

I did not glean that- but it makes sense, although I could see HR do something whimsical with expensive stock, right?

You have to admire the Germans. They wash their windows -the ones on their barns....

pressfit

Yep, victaulic press fit. did quite a little of that back a few years ago. Did a whole school repipe job, among some other smaller things. Gun was heaver than the propress gun. I liked the stuff but it just didnt seam to catch on. Sch 5 pipe & steel fittings.

Was available in SS but i never used it.

fuuny how some "new" things have just come full circle.

It'll Depend...

... on which code applies to the installation, and what kind of joints are being used. I've never seen anything that allows cutting a thread into pipe less than Sch 40. Gouge grooving is counted the same as threading. If roll grooving is being used, then you're not actually removing metal from the pipe wall, and the codes I work with don't require that the depth of groove be counted against you. Welding is the same.

ASTM won't tell you what you can use, or minimum wall thicknesses (or the wall thickness calculations) for the various pipe joints, that'll be the specific code you're working to.

We Ran...

... the steam & condensate lines to a big smokehouse in a meat processing plant 6 or 7 years ago. The smokehouse was manufactured in Germany, and the two factory guys who were doing the final installation & commissioning were using pressed joints on the SS tubing.

Better yet a Curvo with press fittings

This would cut down, or out, the number of 90 and 45 ells used. And a lot of joints. Leaving only tee's and reducing fittings.

Truly a thing of beauty; but still we sweat pipe, (not me)and put in standing pilot water heaters, and rail against the high cost of fuel. In the entire SF bay area(maybe northern cal) there is only one of my suppliers that carries pro-press, so I must carry a full inventory, or get out the torch. Breathtaking shortsightness and stubborness, and hubris. People are still trying to figure out why car plants are closing in Detroit We have met the enemy, and it is us.
