Should gas pipes be insulated?
They are typically either copper or plastic PEX material. While PEX is less at risk of freezing than copper (plastic doesn’t conduct cold the way metal does), both types of pipes need to be protected if they’re exposed to the weather. You don’t, however, have to insulate gas pipes.
Can outside gas pipes freeze?
The simple answer is no, it is highly unlikely that your gas pipes can freeze over. This is because gas is delivered to homes highly pressurised and very dry, meaning even the coldest of temperatures will not affect it. The only way a gas pipe could freeze is if it was installed or repaired incorrectly.
What pipe should be used for gas?
CSST tubing, or corrugated stainless steel tubing, is good for installing gas appliances. These corrugated pipes can bend around corners reducing the number of joints and fittings. Easier to work with than steel pipe and weighs a lot less.
At what temperature does a natural gas line freeze?
Mains supply pipes are highly pressured and so they are made to be resilient. A pipe containing natural gas would have to get extremely cold to freeze – actually about 296.7° degrees Fahrenheit – and would need to be struck with a sledgehammer before there would be any possibility of it breaking.
Should I insulate my gas meter?
Gutters and overhangs accumulate ice, which could break off and damage a meter—or melt during the day and freeze in regulator vents at night. Never box in or wrap your meter with insulation, blankets or plastic—gas meters require open air around them!
What type of pipe insulation is best?
For many residential plumbing applications a PE pipe insulation product like Tubolit® and Tundra® is the perfect option. Economical and easy to install, PE foam insulation will prevent pipes from freezing and keep hot pipes hot and cold pipes cold.

At what point does natural gas freeze?
-297 degrees Fahrenheit
Natural gas is mostly methane, a molecule so resistant to reaching liquid form that it requires massive industrial plants to chill it into liquefied natural gas (LNG). It takes temperatures below -297 degrees Fahrenheit to freeze natural gas — temperatures more likely found in outer space than on Earth.
Why is black iron pipe used for gas lines?
The dark color comes from the iron-oxide formed on its surface during manufacturing. The primary purpose of black steel pipe is to carry natural gas into homes and businesses. The pipe is manufactured without a seam, making it a stronger and safer pipe to carry gas.
