Can copper pipe be used for gas lines?
Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper. Steel piping typically is black with malleable iron or steel fittings.
What size copper pipe is used for gas?

Natural gas does not [itself actually] corrode anything, including copper. Corrosion is a chemical reaction between metal and oxygen. It is the oxygen in the normal air that is mixed in with the gas that would cause any corrosion. The corrosion may also be accelerated by heat and moisture.
What is best pipe for gas line?
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.
What type of copper pipe is used for natural gas?
Types K and L copper tube (ASTM B 88) and ACR tube (ASTM B 280), up to and including 1-inch outside diameter, have been used in fuel gas systems for many years.
How long do copper gas pipes last?

Can I use PEX for gas line?
PEX is cross-linked polyethylene. It is made of polyethylene that has a stronger bond between the different polymer chains that make up the material. As a result of this improvement, PEX is suitable for hot and cold-water applications. It can also be used in some gas applications, where building code allows it.
Is galvanized steel pipe OK for gas line?
Today using galvanized pipe generally presents no threat. If pipe is in the ground it will tend to corrode faster (depends on the soil conditions). Many areas do not allow galvanized pipe underground for gas piping and factory coated steel pipe must be used.
What is the difference between Type K and Type L copper pipe?
Type K is the heaviest. Type L is medium weight and used most often for water lines in homes. Type M is thinner and is used underground or for light domestic water lines if local codes allow.
Is it hard to run a natural gas line?
Installing a gas line is probably not a task to take on as your first do-it-yourself project. However, experienced do-it-yourselfers can install a gas line as safely as a professional. Despite the narrow margin for error, the individual steps are no more demanding than plumbing or electrical work.

Thicker type L and thickest type K are used for gas service lines. Not recommended for use with natural gas in some areas as sulfur content can cause interior flaking.
Can a soft copper tube be used in plumbing?
However soft copper tube such as this, is not considered a plumbing item but an HVAC item. Heating, ventilation and air conditioning contractors refer to tube by its OD, outside diameter. So two parallel trades refer to the same size tube by two different sizes. This can result in frustration and mis-ordered product.
What kind of pipe to use for natural gas?
A. I was a gas service representative for a few years and was instructed that natural gas in copper pipe over some period of years caused copper sulfites which clogged up the pipe with hard, black crystallization. Reps regularly recommended customers switch to galvanized pipes when feasible and steel flex hose connections to gas shut off valves.
