I was looking to order some straight 2.5" alum pipe.

What I have currently is 16ga.

Everything I see says schedule 40? Is that the same, if not whats teh difference?

Thanks

 

wow, the 16g is .065 and the Sch40 is .145. the Sch40 is ALOT thicker

 

Well I know alot of people making manifolds use schedule 10/40/etc. I figured it was alot thicker, but I didn't know by how much.

Thanks.

 

Well, you're trying to compare tube (16ga) to pipe (s/40)... and they are two totally different things.

Tube - Size is based on the OD (outside diameter)
Pipe - Size is based on a theoretical ID (inside diameter).

If you are looking to stick with the 2" OD material then tube is what you're looking for. When you call or look online you need to specify that you are looking for 2" tube and then give them the wall thickness you are looking for (in this case, 16 ga). Calling out pipe is the same and the appropriate sizes and terminology need to be used to ensure that you get the correct material.

The short of it... No, the 16ga and s/40 items are not the same and cannot be compared.

EDIT: The biggest problem I see is fabricators, end users, and even other distributors using incorrect terminology like "piping" to describe tube. Pipe or "piping" should only be used to refer to pipe sized material. "Intercooler piping" should be called tubing because of the material used to make it.

 

Wait- so you're trying to make a header from aluminum?
Failboat?

No, i/c piping, I was just using the comparison I've seen in making manifolds with sch 40 stuff.

Thanks for the help all, I was unaware in the difference between piping & tubing.
