compressed air pipe

compressed air pipe

(OP)
Hello, guys,

Can anybody recommend a material for compressed air pipe in a lab?  Let's say the pressure is around 10 bar (not very high).

Thanks!

RE: compressed air pipe

Depending on the type of lab, black steel, stainless steel or copper would work.

RE: compressed air pipe

I see copper or black pipe all the time.  Just make sure it and the connections can handle 10 bar - really a no-brainer...

RE: compressed air pipe

I wouldn't use hdpe in a lab, i'd go for ABS.  Rigid pipe looks better and slopes better and uses bonded connections which are cheaper and easier to pipe than hdpe.

You can do the main runs in galv, black steel will corrode unless you have good drying.  Filter at the terminations, particularly with galv as it flakes into the airstream.   

RE: compressed air pipe

See if you can find a millwright's handbook to show you how to install drip legs and drains at the outlets, to catch the crud and water that _will_ be present.

RE: compressed air pipe

The HDPE I'm talking about is TUBING, not pipe.  Connections are push and lock- can be done without tools.  This assumes a few users, not big enough to justify a line even as large as 1/2" pipe.  If you're above 1/2" pipe size, of course you'd go with black steel pipe or copper.

ASTM A53-B Galvanized  ...use it all the time for instrument air piping

RE: compressed air pipe

I've used rigid abs pipes for a while in our lab and it's working fine.
