Superior Propane covers all your gas needs including piping. Whether
you need the underground line from the tank to your home or business or interior
piping Superior is who to call. We follow all building codes and only use
the highest quality materials. All piping is installed by a certified
propane technician and pressure tested to twice the needed pressure to ensure
safety.

To the left are the components that create
the underground line that supplies propane gas to your home or business.
The yellow pipe is Polyethylene Pipe. The common size is 1/2 inch
inside diameter. It is flexible and does not need to be buried using
any special material. Polyethylene Pipe is for underground use only.
The Gray pipes are Risers used to come out the ground at the tank and the
building. These connect to the polyethylene underground.
The red disk is a High Pressure Regulator, this takes the pressure in
the tank and lowers it to 10 Lbs for delivery through the polyethylene.
The green Regulators are the Low Pressure Regulators, these lower the
pressure once again from 10 Lbs in the underground line to 1/2 Lb for
delivery to the appliances. |

Stainless Steel Tubing, or CSST, seen at right, is used for interior
piping. This Type of pipe is far superior to iron piping, seen
below. CSST can be bent and shaped around corners, and does not need
to be passed through wall studs in a straight line. CSST uses special
fittings, the black disk is a termination, these are at every end of CSST,
on the outside of the building and at every appliance. The T fitting
is just that, a T, used to take the CSST in two directions. The last
fitting is a Pipe To Flex used to go from CSST to iron pipe when
necessary. |

Pictured here are
various lengths of Iron Pipe. With the pipe are the common fittings.
The most common size used for propane gas is 3/4 inch inside diameter.
In the center of the picture are ball valves. The yellow handle is a
Main Shutoff used outside the building to shutoff the gas flow. The
red handled valve is an Appliance Shutoff used to stop the flow of gas to
individual appliances. Every appliance must have a shutoff.
Shutoffs are required by Arizona codes.
The final fitting is Dielectric Union, it is insulated to stop the flow
of electricity should a lightning strike occur or something similar.
This fitting is required by Arizona building codes. |
