No, but basic physics indicates that with the same ID, OD, and material the solid will be stronger than the foam core. The question is whether it is still strong enough. Since if is used for at least some buried waste lines it seems to be good enough for some applications.

The conduit version has to pass the same testing as does the solid wall PVC conduit. It is still listed as PVC conduit.

I was referring to the plumbing version before it was mentioned that there is listed electrical foam core.

Also plumbing pipe is measured OD and electrical pipe is measured ID.

I got curious and looked up the Cantex product. Listed to UL651 all right, but the smallest trade size is 2", which may be part of the reason I have not seen it.

Here is the issue with water pipe used for underground electrical.
Contractor is installing a 8" sewer line, there is a 1" pvc water line in the way, we'll cut thru it, route around our line, and reconnect.
Ops there were wires in it!

[ritelec]

Are you going to try & pull conductors thru a plumbing elbow ?

no?

I did for heat tape for flat roof drains.

Cork. Eye hook. Fishing line. Couple buckets of water


Actually. After that. Ran into a job with existing plunging PVC for outside wall lighting
No pitch on the pipe so I used a hose.

:- )

Just throwing that out there.

Also plumbing pipe is measured OD and electrical pipe is measured ID.

Some piping is referenced by OD, some by ID, some by a nominal size that is close to OD or ID but is not the exact dimension.

Schedule 40 and schedule 80 have same OD whether they be plumbing, electrical, or otherwise, and whether they be metallic or non metallic. There are a few other wall thickness or types that also have same OD. All those I just mentioned are nominal sized and very few of them have the exact dimension as they are named for.

Piping is nominal OD, but in plumbing tubing is ID. I don't think our tubing is ID.

 

[GoldDigger]

Piping is nominal OD, but in plumbing tubing is ID. I don't think our tubing is ID.

And just what is the dividing line between pipe and tubing in both fields?
I would guess that EMT is tubing while both RGS and PVC would be pipe?

In the plumbing field it is just what that call it. There is both copper pipe and copper tubing....the pipe goes by the OD and the tubing goes by the ID. Way back when I worked a the local hardware store that made for a lot of confusion and often resulted in multiple trips to the store.

CTS = copper tube size which is the OD. PEX and CPVC are made to CTS.

 

[John120/240]

CTS = copper tube size which is the OD. PEX and CPVC are made to CTS.

That make sense, it allows one to marry copper with PEX via Shark Bite fittings.

For me I guess it would depend on the immediate application. Good question though!

Ah, but Copper Tube Size (CTS) is ID! A 3/4" type K copper pipe is .875" OD. That is not 3/4". The ID of 3/4" type K is .745", that's 3/4" to most people.

However, since there is also type L, and Type M, with the wall thickness being the difference between types, "they" kept the OD the same for all three types, and let the ID change. Type M ID is .811". The OD of CTS pipe/tubing is .125" greater than the size listed. Even for DWV and gas rated copper.

Then "they" made PEX and PB to the same CTS standard OD measurements. So these (CTS pipes/tubing) are all standardized to an OD, but sized by number to close to their ID. My head is spinning....

The only OD sized tubing I know of is in the refrigeration field, ACR (Air-Conditioning and Refrigeration) copper tubing. If you work with that, most of the time you need to visit the HVAC supply store to get fittings.

Now what was the original question?:?

Soft copper tubing standardized by OD is also used for plumbing at times.

The Palace of Westminster (Houses of Parliament) is long overdue a rewire, the specification is for copper conduit. I wonder who will get the job, the electricians or the plumbers?
