Gas supply lines

[William M. Corbett]

O.K. Show of hands.
Scenario... Copper gas supply line passes through block wall, no insulating sleeve.
I know many of the Northerner's do not allow soft copper for gas, but for all others, how many of the HI's would write it up and why?

That's funny....we protect all of our (soft copper) oil lines with a coating of mortar here in Massachusetts.

Please tell me more....

We used to be able to do that up here, countless installations of soft copper buried in the basement concrete floor. But Charlie is right, the lines will corrode and leak over time. We are not allowed to install this way any more, all lines must be above ground.

Hmmm...We still do it everyday on new construction.

Must be a location thing.

Is the line protected in any way? If not this is bound to happen:



Note the leak in line at mid point.

Like I already stated, we cover every oil line with a complete coat of mortar.

That is right Charlie, the lime in any and all masonry reacts with copper and causes little pins holes (sometimes in wall cavities). Get the right fuel to air mixture, unplug the vacuum and then ! So for those of you who have jurisdictions that allow this, please write it up. </IMG></IMG>

Is There A Problem With Embedding Copper Tube In Concrete?

[William M. Corbett]

Any type of pretective sleeve where in contact with concrete, brick, block et cetera will be sufficient, at least in this neck of the woods.

Thanks Mike.

David,

You're welcome. It's a great site for all things copper.

Interesting, but I have seen them after the leaking has occured. As with buried oil tanks, it is a huge cost to clean up.
