compressed air pipe

[nickyl82]

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!

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

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

Just a few instrument air connections in a lab? Nylon or HDPE tubing and Legris fittings:

No tools needed to assemble, easy to modify/change, and very safe. Just mount the main line with enough clips to the wall to keep it safe from mechanical damage.

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.

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.

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

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