Best Gas Pipe – Buyers Guide!

Gas Pipe
Written by Ken Coul

When you want to connect a grill, or perhaps a laboratory device, you automatically require a reliable natural gas pipe. These pipes come in many forms, ranging from an underground gas pipe to a flexible gas pipe. There are many different types, and each one is designed for specific purposes.

More Information

That is why, when you want to connect a gas source to an appliance, you have to factor in three main considerations:

Distance, Pressure and Gas type.

Obviously the further the distance the more pressure you need in the system, and this requires a stronger pipe. Different gas types react to different materials, so you need to stick with industrial standards. Finally, the actual source can be a small tank connected to a grill, or the main gas supply connecting to a large industrial burner. The range of piping is as varied as the different types of gas there are.

In this review, I present to you a list of the top ten flexible pipes that can be used with most standard fuel gasses, including natural gas, and propane. These pipes are all chosen based on their production conformance to standards, and the materials used for safety and reliability.

FAQ

What pipes are used for gas?

There are a number of options to use for gas pipes. However the most popular is the Corrugated Stainless-Steel Tubing(CSST) which use a stainless-steel tubing with a synthetic coating, inside and outside the tubing. In some instances, thick PVC and polyethylene (PE) pipes are used for buried outside pipes. In many cases, you will find older constructions that used iron (black iron), as well as copper, brass, and aluminum. However, those are rigid pipes, while the CSST versions are flexible.

When choosing a pipe, make sure you understand the application, this includes the distance from the gas source to the appliance, the amount of gas needed to supply (PSI), and the number of appliances that might be needed to attach to the main supply source.

In most instances, you will find rigid piping for indoor construction, such as copper and CSST, and flexible piping for outdoor applications as well as some modern housing constructions. Underground applications use PE and PVC tubing, while short applications will use CSST.

What material is commonly used for gas piping in the house?

As I mentioned above, there are a number of materials that are used in gas pipe systems. These all depend on the type of application, whether the requirement is for a fixed system, a large system, as well as for mobile systems. Other indications to decide what material is best used are environments, which include industrial, residential and Medical.

Essentially, today, most gas piping systems are designed according to the amount of gas required for delivery. The larger the amount required, and the distance required to supply this gas will lead them to the use of wider, stronger metals. Rather than go into too much detail, here is a chart showing the pipe size required for different applications based on the required pressure.

  • Steel Pipes

Steel pipes are used above ground when there are no corrosion issues, and due to the environment and Steel pipes and copper pipes are still the most common gas piping materials used inside buildings.

  • Copper Pipes

These pipes need to be either L or K and approved for gas.

  • Yellow Brass Pipes

Yellow brass pipes are used for inside installations.

  • Aluminum Pipes

Aluminum pipes are not allowed for use underground, and in most cases are not approved for use.

  • Ductile Iron

Not usually used anymore, but can still be found in some countries.

  • PVC Pipes

PVC – Polyvinyl Chloride – are usually used outside, and underground.

  • PE Pipes

PE – Polyethylene – like PVC are used outside and underground.

Can you use galvanized pipe for gas lines?

No, galvanized steel is Zinc plated steel, and there are issues with the “galvanic” reaction between the zinc and steel. As such, regular galvanized iron is never used for natural gas lines. The pipe is simply an iron or steel pipe that has been coated with zinc for protection from corrosion, and yes, there will be a dissimilar metal or galvanic reaction between black iron and the galvanized coating.

Is flexible gas line safe?

Yes, if it is made according to standard. Today, most flexible pipes are made of a Corrugated Stainless Steel Tubing (CSST) which is both flexible and strong. Most grill gas lines you see today, both outdoor and indoor are CSST.

These types of tubes are used in many locations and are starting to take over from the conventional rigid pipe system. Laboratories especially prefer CSST to copper and iron.
