Gas Piping Types and Purposes

Most of my neighbors and customers looking for gas pipe repair & installations don’t realize that plumbers do that. In fact, the proper designation for a certified plumber in this region of the country is Master Gas Fitter and Plumber. There’s a wide range of work in our industry related to natural gas and liquid propane. In this blog post I’ll discuss the different pipe materials related to this part of our industry as well as the appliances they serve.

Fall Brings Appliance sales 

Every fall our newspapers are full of sales ads for appliances.This, along with the wonderful weather, gets the creative juices flowing and the home improvements begin. That’s when our customers inundate us with requests for assistance with the following projects:

  • Range conversions from electric to gas
  • Backyard grill conversions from LP to natural gas
  • Water Heater repairs and installations
  • Pool heater installations
  • Fireplace inserts and gas logs
  • Furnace gas leaks

None of these should be installed by the novice plumber. Because of the inherent danger of natural gas and liquid propane, plumbers are specially trained in the sizing, installation and repair of gas piping. It’s not enough to know how to do it. You have to know why it’s done that way. If you don’t you may run across a situation that demands a judgement call. Leave it to the professionals at Advocate Master Plumbing.

 Types of Gas Piping

There are three main types of gas piping that the average home owner will come across.

  • Black Iron Gas Pipe
  • Copper
  • Corrugated Stainless Steel Tubing (CSST)
  • Polyethylene (PE) Gas Piping

First there’s Black iron gas piping. It can be seen in all older homes. It’s the primary gas piping serving your home. It will be black iron from the gas meter to your furnace and water heaters.

Then there’s Copper gas piping. It is seen in many of these same homes. But usually it’s only a branch line supplying a water heater or fireplace. This is due to it’s flexibility.

Next there’s corrugated stainless steel tubing or CSST. It is a newer type of piping. It’s used in new home construction and remodels. It’s flexibility and ease of installation has made it a favorite of home builders and plumbers when making gas pipie repair & installations. You probably have some in your home in the shape of a flexible gas connector for your gas range, gas water heater or furnace. When running this piping for remodel projects it’s important to install the electrically grounded type. Lightening strikes were creating leaks.

Lastly there’s polyethylene gas piping. You’ll probably not see this pipe. It’s used almost exclusively in natural gas underground services.

Differences Between Natural Gas & Propane

If you live in the city you probably have natural gas. If you live in the country you probably have propane. The reason for this is infrastructure. Your local government hasn’t installed any natural gas service mains in your area. For this reason, you have to have the most readily available gas that can be economically stored.

Propane is, like natural gas, odorless and colorless. An agent is added to allow us to smell it. This is for safety purposes. If too much is allowed to build up from a blown out appliance pilot light it could explode.

Many plumbers prefer not to work with propane because it is more dangerous than natural gas. This is because, unlike natural gas, it is heavier than air. If a leak occurs, it will pool up like undetectable water. Once it reaches a flame, such as a water heater pilot light, it will explode. And because it’s been allowed to build up so much the explosion will be spectacular.

Natural gas, on the other hand, is lighter than air. Most leaks are undetected because it will float and dissipate into the atmosphere. But if it’s in a confined space such as a floor joist, it can build up. If you’re working in this space it would be easy to ignite it. But you’d probably smell it. The agent added to natural gas will be almost overwhelming before it reaches the necessary concentration for ignition.
