MC-9 LP Gas Piping Installation

I guess you know what your talking about but I have never saw sch 20 (.125) used for any threaded gas pipe it's always been sch 40 seamless you thread a piece of .125 wall there is hardly any pipe left JMO

Dear Cliff,

It was a copy and paste from the website. I believe you are right... I think Black Pipe has a thicker wall.

I've worn many hats, but never the one for a plumber. I'm learning as I go.

Here is some more information and quite frankly, something I totally forgot.

Scenario... A Coach is parked at a campsite. A nearby tree is struck by lightning. The resultant magnetic field produced by the strike induces an electrical surge in the electrical and piping systems of the nearby Coach and causes significant damage.

From: http://csstsafety.com/CSST-solution.html

"Nearby lightning strikes can also result in an electrical surge and can potentially puncture a hole in the CSST."

An AM Radio Station Tower has guy lines that have been deliberately cut to irregular lengths to eliminate any possibly of harmonic resonance. If the Tower is 50,000 watts hot, a nearby wire that is at a resonant length is also 50,000 watts hot. The reason is resonance. Even the cyclone fencing that surrounds the tuning houses is calculated.

"The real problem: CSST is so thin-walled that it creates a significant fire hazard anywhere it is installed.

CSST gas line is extremely thin, with walls typically around 0.008" in thickness. Black iron gas pipe is typically 0.12" in thickness.
Put another way, the walls of black iron pipe are 15 times thicker than the walls of CSST tubing. When this is considered,
perhaps it is not surprising that the amount of electrical energy needed to defeat traditional black iron pipe is about 15 times more
than the energy needed to defeat the much thinner walls of CSST tubing."

.008 is really thin; its not even on the fraction to decimal chart; it is 1/128".  I thought it was at least .035 which is thin also.

Black Pipe is .125 which is an 1/8" wall.

If this doesn't give you cause for pause, I guess nothing will.

If you ever consider going back to black pipe, I have all of the tools and I will help you for free.


Sincerely,
Mike

Thanks for the offer, Mike. I have no reason to change to black pipe. My LP system is installed and functional. I have no reason to believe it is unsafe.

The two examples you cited relate to CSST in homes. As for the first one, I'm sure you know what a Faraday Cage is, from your special effects and other
experiences. If not, look it up online and learn about it. You've probably heard that you are safe in a vehicle during a lightening storm, and probably
you heard that it's because the vehicle is insulated on rubber tires. That's not the real reason. An automobile, and also as bus, is a very large Faraday Cage.
I am not concerned about lightening strikes in the least. I actually was in a campground in Montana in 2005 when lightning took out 2/3 of the campground,
including the site we were hooked up to. Initially I thought my inverter had fried, but it just shut down because when the power went out, it tried to take
over the full load which included 2 a/c compressors and an electric element in the water heater which overloaded it's capacity. No holes in the gas line.

And while the thinness of the CSST walls could potentially be a concern, proper installation is the key to alleviating any problems. It must be supported properly, and
it must be protected from chaffing, as in alluded to earlier. That's as simple as drilling or punching properly sized holes and inserting rubber grommets and
feeding the CSST tubing through the grommets. Run support is handled effectively by placing rubber faced stainless hanger straps at appropriate distances.

Again, black pipe is a tried and true means of handling LP distribution. It, too, has some down sides but if assembled properly, it will give you years and years of
good service.
