NY State Plumbing Code clarification?

Table 308.5-Hanger Spacing

It has different spacing for "Copper or copper-alloy pipe" and "Copper or copper-alloy tubing"

What's the difference between pipe and tubing? Is it just the connectors?[/code]

[Rich]

I believe pipe is type M, K, or L (rigid) and Tubing is soft pipe. Would imagine the spacing is greater for pipe?

[giddonah]

12 for pipe, 10 for tubing greater than 1 1/2 and 6 for tubing less than 1 1/4 (feet)

Where do they draw the line for soft pipe, or do they just not make an ambiguous product like that?

[roger g]

Piping comes in lengths and is measured inside diameter and tubing comes in rolls and is measures outside diameter. 5/8 tubing is the same as 1/2 pipe.

Ah, ok. Is there any chance of confusing the two (say, if it's alreay installed)?

[roger g]

I don't know what you mean by confusing. Tubing, because it comes in a roll, even when straightened, never looks as straight as piping. Half inch tubing looks smaller than half inch piping. They are the same colour.
Confusing? not to me.
