Hi Bruce
Here is a link to some information regarding plastic pipe and compressed air.
http://orosha.org/pdf/pubs/fact_sheets/fs44.pdf
http://hydraulicspneumatics.com/200/TechZone/FluidPowerAcces/Article/False/6547/TechZone-FluidPowerAcces
Plastic pipe needs to be enclosed in a protective enclosure, concrete floor or inside a wall. If the pipe is hit and fractured the
escaping air can create flying shrapnel that is dangerous.
Buried in the concrete floor is OK but anything on the surface needs to be metal or plastic approved for compressed air.

Dave,
Thanks for providing those two references, I must apologize, I ASSUMED that the sprinkler tubing sold in the USA and Canada was the
same as what is sold here. I checked Lowe's and evidently it is not. Over there you use PVC, here in Australia they use HDPE.
Reference: http://orosha.org/pdf/pubs/fact_sheets/fs44.pdf
Plastic pipe used for compressed air service must be designed for such service by the manufacturer. Examples of such pipe include
high-density polyethylene (HDPE) and Acrylonitrile Butadiene Styrene (ABS). Compressed air piping systems that use plastic pipe must
also be "project specific" - i.e., suited for a particular application or project - and installed by a competent person.
Reference: http://hydraulicspneumatics.com/200/TechZone/FluidPowerAcces/Article/False/6547/TechZone-FluidPowerAcces
An attractive alternative to PVC
New thermoplastic piping systems -- using high-density polyethylene (HDPE), for example -- overcome the brittleness problems
associated with PVC. They efficiently and reliably deliver compressed air with lower material and installation costs and longer
service life than with metal systems. They offer a margin of safety missing from PVC.
I consider myself to be a competent person and to demonstrate that when I plumbed my shop here's a rough description of the system.
The HDPE leaves the compressor and goes straight up to the height of my mezzanine (12 feet). It traverses the horizontal section of
the mezzanine inside the main "I" beam which protects it from being hit. There are two down drops and a pull out reel that service
the ground floor. The down drops are attached to the walls and stop at 3 feet above the floor. One is next to the pneumatically
raised / lowered motorcycle stand the second up against the wall next to my workbench. The pull out reel is attached to the bottom
of the mezzanine. There is a section of pipe that continues vertically to the bottom of the roof rafters attached inside the main
roof support vertical beam. It has one down drop which stops 3 feet from the floor next to my Smithy machine. When it reaches the
roof rafters it runs inside the main roof support I beam to another pull down hose reel that services the rest of the mezzanine
level.
By the way I got samples of the tubing and fittings sold for compressed air systems here and in ground sprinklers and they were
EXACTLY the same.
This system has been I in service since 2003 and has gone through innumerable pressure cycles (I shut the compressor down when I
leave the shop) without incident.
Regards,
Rob M.

Bruce,
The Murray Mansion is coming along nicely. Your coach is in such nice shape that I'm not sure what work you'll do on it in there other than changing the oil and polishing it.
The plans showed some steel columns in axis with the main beam between the bays. I can't see them in the pictures. Are they in there or have they been omitted?

Hi
Ipex Inc. in Mississauga sells the HDPE-Al-HDPE tubing in 100 foot rolls. It is ASME, ASTM, CSA, and OSHA approved. I have no idea
who all those people are but it sounds impressive.

http://www.ipexinc.com/Content/Products/Product.aspx?IsDownload=true&FileId=967
They also have the nice looking fittings, looks expensive but maybe worthwhile when one is sparing no expense to provide a warm
secure home for ones GMC.

Since we come up so many ideas with our coaches we could develop the
ultimate garage. Gmc man cave. Gmc shelter. Gmc ramp for sloped properties
like I did.

I've had air lines built in in all my shops and used copper before but if I were doing it today I would be using PEX. I never even considered it before my plumber friend used it in his shop about 10 years ago. It's inexpensive, VERY easy to install and durable. He used about a 24" piece of copper before the terminations and it works great. Of course he used an expansion tool and fittings which IMHO are the best method to install PEX.
Anyway, just another idea.

Richard,
I'm not sure what the exact issue was, but the roof truss engineer found an issue with that beam and posts just as the footings were being dug.
Between all those with letters behind their names, an adjustment was made to the footings and 2x6 x 4pcs posts along with a mega laminate beam was used instead.
|
Bruce,
I'd mentioned that the posts and beam needed to be detailed. There were some odd things about it. I didn't understand the location or purpose of those steel columns at all. I'm glad they figured out their error before it was built. The LVL is also a much better beam for the reasons I mentioned.
The stub walls along the central beam axis will be called on as shear walls in high winds, and the sheathing on those walls should probably be nailed on a shear wall schedule. I haven't done any calculations, but that should be adequate. Another option would be to sheath both sides of those stub walls with plywood/OSB. Little precautions can make a big difference.

Do yourself a favor and put the compressor in another enclosure on the outside of your shop ( back). Not having to listen to / yell over it is nice.

Pre-finished pegboard for at least the upper 1/2 of the interior walls. As
your memory fails, it will be much easier to find things hanging on the
wall than hidden in cabinets. Trust the voice of experience. :-)
