Was in the shop shortly after the shop foreman had added onto the air system. PVC After what was considered by the owner and foreman to be enough time for the glue to set up, the system was recharged. About 15 min IIRC after the system was re-pressurized, the freshly added section let loose!!! After changing our shorts we started gathering the pieces of the PVC valve that had blown directly down into the concrete floor. Pieces had deflected in all directions to the extant of the shop.
Fortunately no one was hit by any of the considerable projectiles. One guy was about six feet away from the "explosion". Some time after we started picking up the pieces, the owner came out of his office. Always wondered if he was under his desk with carry piece drawn waiting for some one to come through the door.
Since then I've favored copper. Join Date Aug Location So. I used the same schematic that Michael posted above. One big advantage of copper is that it cools down the air a lot faster than PVC if you're worried about condensation in the air lines for painting. Sata recommends a minimum of 50 feet of copper pipe before the first airline that will be used for a spray gun, 75 feet if using black pipe. I didn't have that much space in my garage, so I built a copper zig-zag coil system with a total length of 35' coming right out of the air compressor, and the thermal differential from the beginning to the end of the run is amazing!
Type M copper water pipe isn't approved for compressed gases. It must be type L or K. Type M is prohibited by code. Also, copper pipe shop air systems must be brazed, not soft soldered. I worked for an Ingersoll Rand dealer as tech for air compressors.
Basicaly if a plant had any type of PVC used for airline, we didn't step inside. The oil from a compressor will work from the inside out, no warning till it lets loose.
The plant was very lucky that the pipe blew on a weekend. Usually a failure will start at one point and then progress down the line like a lit fuse. A normal air filter will not remove enough oil to make PVC safe, it just slows down the time bomb!
A cololesncing sp filter will remove Even if nothing happens for years, it is not worth the risk to use PVC. Any info about PEX as airline? One possibility my tack is to use Stay-Brite 8 solder on the airlines. Step 5. Installation 4" - 6".
Do not overbend. FastPipe can be bent to conform around minor obstacles to a maximum of 15 degrees. Any piping system will expand and contract with temperature changes. Gas must be warmed up to FastPipe temperature range. Use a strain relief attached to the building for any rubber hose drops attached to the piping. DO NOT connect quick couplings for air hoses to reduce elbows or tee fittings. Use the FastPipe Wall Outlet, which can be secured to a wall or post.
Any hoses attached in the ceiling area to a fitting must use a strain relief attached to the building structure. FastPipe is not designed to electrically ground equipment, to be welded, to take violent impacts or for environments of caustic or corrosive chemicals. While MaxLine fittings do not interchange directly with FastPipe, the two systems can be joined through pipe thread adapter fittings.
Check that all fittings are tightened before pressurizing the system for the first time. Then, pressurize slowly to MAX psi. Some settling of components may have occurred. This is not optional. It must be done. Pipe needs no covering and can be exposed.
Keep children away from the system. Happy Customers. Thanks for all the help in setting up my system. Everything works great with no leaks anywhere.
The convenience of having multiple outlets in my workshop is fantastic. Greg Contact options for registered users. Reply to Greg. Ed Angell Contact options for registered users. It's easy, if you sweat the fitting on to at least 12" of pipe, thread the stubs into you plastic stuff.
Wrap a wet rag on the stub near the plastic and sweat the assembly into your system with couplings. Another option would be to put a tee at the place you want the regulator, sweat in a slip to thread adapter, add the regulator after the system is plumbed. Don't forget to put water legs at the compressor inlet to the system and before your regulator.
