[TheForge] propane lines

[Terry L. Ridder]

hello;

is this a high pressure or low pressure propane gas line?

according to nfpa, if high pressure propane gas line,
it needs to be welded or brazed.

i have high pressure in the shop, 20 psig, the system
to welded. each quick disconnect is required to have
a gas shutoff value, specifically a ball value. 90 degrees
turn to open or shut. my quick disconnects are mounted on
the walls and there are none in the ceiling.

borrow, the lpg gas handbook from your propane dealer. published
by nfpa. there is also nfpa-54 and nfpa-58 which are the
basis for most local codes.

if a propane line through a wall there must be a shutoff
value on each side of the wall. this does make sense in
that you are able to shutoff gas flow if needed from either
area.

also you want an excess flow value installed between the bulk
tank and the shop. if the propane gas flow exceeds the setting
of the excess flow value it shuts off the propane gas flow.
most excess flow values need to be manually reset. the point
is if the propane gas line to ruptured you want the flow of
gas to stop as soon as possible.

i would suggest that you have one of the senior propane
service company techs out for a visit and explain what you
are trying to do. they should know the propane code and the
lpg handbook extremely well if not by heart.
