Sources for 1.5" 316 Stainless

[AndrewA2]

Have my parts list of solar arch. Looking for suppliers for the stainless and fittings.
Found https://www.markstaar.com/ but cant find much info on how reliable they are.
So want to check around before committing my order.
Only other place i can find is www.buyrailings.com but they doesn't have all the parts i need.
Open to recommendations and/or suggestions.
Im on the Mississippi coast if that matters (assume i would get parts shipped but hey, if its local all the better )

Thanks !

Not the cheapest but Onlinemetals.com has 1-1/2” 316ss tubing.

I would check Fazios out of NJ. I believe they will ship.

But are you looking for tube or fittings?

Most arches I see are welded.

Good questions!!!
I need both tube and fittings.
I'm not going to weld!!! I'm going to try something new. SSF-6 silver. Basically sweating the joints with this stuff that has a 70,000lbs rating....
I'll take a chance and let you all know how it works out. Especially as I live in a hurricane region!!!!

What I hear you saying is you are going to do slip joints, an inner sleeve under the butt. ????

In that case you need to watch closely the ID and OD.

In the case you do not know:
TUBE gives the exact OD and the ID shrinks as the wall thickness increases.
PIPE gives the approximate ID and the OD increases as the wall thickness increases.

Therefore you may want to carefully select a bit if pipe that just fits within hour tube for reinforcing the butt welds.

If I understand you correctly.

Also, you may want to consider using electrical conduit - pipe.

If you do then you can buy pre-made elbows for the 90s.

I made my arch out of 1-1/4” steel, I used elbows and couplings. The couplings were not stiff enough so I ended up welding the in place.

If I were to do it again I would use aluminum conduit. But I would either again weld the couplings or do butt welds with some internal coupling.

That’s not the case pipe od is fixed by a standard. The id changes according to the wall thickness.
The nominal size of a pipe equates to a historical id but od is alway fixed according to Ansi standards in US.
Tubing is detailed by its od
Ie 1” tube is always 1” od a 1” pipe is always 1.315 od regardless of id.

This is where I get most of my metal from.

Paul,

You are simply adding a detail.

1” TUBE is 1” OD by measure
1” PIPE is NOT 1” by measure, you need to go to some source to look up the actual dimensions, or measure yourself.

From the pipe example below:
1” schedule 40 is 1.312”
1” schedule 80 is 1.32”

The important point for the OP to know is that he may be able to find a size of pipe that will slip snugly inside his tube if he looks.

[Manateeman]

This is a common size used in food processing, pharmaceutical and breweries.
All sorts of pre-made bends, tees and other fittings end up in the scrap yard.
Try to find a scrap yard. Long lengths are difficult and the tubes are thin.
You could reinforce the structure but high strength joints are usually done with TIG and the interior filled with argon.
It’s a whole lot easier to build in aluminum. There are some great tuna tower builders near you who could whip this out for a reasonable price in anodized or polished aluminum. I’m not sure why you want to use stainless.
Happy trails to you.

Manateeman,

I built my arch for under $300 out of electrical conduit. The advantage was cheap and strong.

If I were to do it again I would do as you advise. Aluminum.

[Steel sails]

Well I can assure you online metals is wrong.

I have been in the pipe manufacturing business for over 40 years.
We are ISO and AS9100 certified
See www.Ippgrp.com

For the correct sizes of pipe od you can google ANSI B36.10

Respectfully
Paul

My arch is 15' long, 6' wide, with 7-8' deep supports... think stainless is the key here!
Going 1.5" OD 316 stainless

Its for a 4 full sized panels extending the flybridge on my catamaran

Paul,

I stand corrected. I see now that my source (Engineering notebook) was rounding to 2 decimal places in some tables and 3 decimals on others. Thus 1.315” rounds to 1.32”. Rather annoying that a single source produces two tables with different tolerances; 2 and 3 decimal places.

Thanks for politely correcting me.

PS: I have done some old work where I was exposed to the IPS measurement system and that stuck in my head. None the less for anything remotely modern your point stands.

We had a Hunter 50? a while ago with a much smaller arch than what you are considering. Maybe 12' across, similar height and width was 2 feet. It was super wobbly and it was welded SS. Aluminum or SS I think you need more diameter and really have to figure out how you're going to attach it securely. It didn't have many cross braces and that would have helped a lot
