CSST is much less expensive to install
than black iron gas pi
pe, and as a result,
CSST has been installed in millions upon millions of homes across the U.S.
– 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. Pu
t 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 el
ectrical 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.
When electrical energy from lightning is
conducted through CSST tubing, electrical
arcing can be created between the CSST and any grounded metallic object, as the lightning
energy seeks a ground source. This arcing can instantaneously burn a small hole, ranging from
the size of a pin-head to a pencil eraser, right th
rough the very thin wall of the CSST. The arcing
event can easily ignite the escaping gas being ca
rried by the CSST, which can then serve as a
blow-torch with an endless gas fuel source more than sufficient to ignite nearly any type of
