You may have seen galvanized pipe used for propane in a variety of ways and wondered if it’s safe. It can be confusing to know what type of piping is safe for propane and which ones should be avoided.
Plumbing and other water-supply applications use galvanized pipe, and propane can also be carried by it. There are a few things you need to know before getting started.
This guide will teach you explain why you can use galvanized pipe for propane, from what type of galvanized pipe is best to how to connect it all up.
How can You Use Galvanized Pipe for Propane : Explanation
So, you have some experience using propane around the house, but you’re not quite sure how to get started using a galvanized pipe with propane. Well, before we start, there are some things you should know.
Choosing the right type of galvanized steel pipe is the first step. There are two types of galvanized pipe: black and hot-dip. Black galvanized pipe is less expensive but also less durable. Hot-dip galvanized pipes are more expensive but will last longer. For propane applications, it’s best to use a hot-dip galvanized steel pipe.
Second, you need to make sure the pipe is properly rated for propane. All galvanized pipes are not created equal, and some are not rated for propane use. Make sure to check the rating before purchasing the pipe.
Third, you’ll need to connect the pipe to your propane tank using a pressure regulator and a natural gas line. The pressure regulator will help to keep the pressure in the pipe at a safe level, and the natural gas line will make it easier to attach the pipe to the tank.
Fourth, you need to be aware of the potential for corrosion. Galvanized pipe is more resistant to corrosion than other types of pipe, but it’s still important to take steps to protect the pipe from corrosion. One way to do this is to coat the inside of the pipe with corrosion-resistant paint. This will help extend the pipe’s life and keep it working properly for longer.
Another option is to wrap the outside of the pipe in corrosion-proof tape. This will also help to protect the line from corrosion and extend its life. Finally, you need to check the pipe regularly for signs of corrosion. If you see any signs of corrosion, you’ll need to work on a plan to repair or replace the pipe as soon as possible.
The use of galvanized propane pipe is a great way to save money and extend the lifespan of your propane system. Just be sure to take the time to choose the right pipe and avoid corrosion.
The Advantage and Disadvantages of Using Galvanized Pipe for Propane
While galvanized pipes are a common choice for propane applications, there are both advantages and disadvantages to using this type of pipe. Here are some basics to consider when making your decision.
Advantages:
- Galvanized pipe is corrosion resistant and will not rust over time like other types of propane piping.
- The zinc coating on galvanized pipe protects it from damage by UV rays, making it ideal for exposed piping applications.
- Galvanized pipe is more durable than non-galvanized pipe and will last longer.
- Galvanized pipe is easier to install than non-galvanized pipe, as the zinc coating provides a smooth surface that is less likely to catch on installation tools or clothing.
- Galvanized pipe will not freeze in cold weather since the zinc coating helps to protect against freezing temperatures.
- Galvanized pipes are more fire-resistant than steel pipes because their zinc coating acts as a barrier to fire.
- It is less likely for galvanized pipes to become brittle and crack over time since the zinc coating will prevent corrosion and degradation.
- The pipe is unlikely to warp or deform due to its zinc coating, which helps protect it against corrosion and degradation.
Disadvantages:
- The cost of galvanized pipes is higher than that of other kinds of pipes.
- Some galvanized pipes may not be suitable for high-pressure applications.
- There is a possibility of corrosion and leaks in galvanized pipes.
- Several types of fittings and connections may not be compatible with galvanized pipes.
- There is the potential that galvanized pipe is not suitable for underground usage.
- It may be necessary to follow special installation and handling procedures when installing galvanized pipes.
- The lifespan of galvanized pipes may be shorter than of other pipe types like plastic, steel, and aluminum.
- Pipes made from galvanized steel may not be as aesthetically pleasing as other pipe types.
- Normally, galvanized steel pipe needs to undergo regular maintenance and repair activities.
- Lastly, the galvanized pipe may pose a health hazard if it leaches into the water supply.
Choose the Correct Galvanized Pipe for Propane
When selecting a galvanized pipe for propane, be sure to select the proper type of pipe. There are three types of galvanized pipes: black, hot-dip, and pre-galvanized.
Black pipe is uncoated and made from steel that has been heated during its manufacture. Hot-dip galvanized pipe is dipped into a vat of molten zinc, which gives it a thick outer coating of zinc. The pre-galvanized pipe is steel that is coated with a layer of zinc during its manufacture.
The kind of galvanized pipe that you select will depend on the intended use. If you need a pipe exposed to the elements, such as for outdoor propane tanks, you will need to choose a galvanized copper pipe. If the pipe is used indoors, you can choose either a black or pre-galvanized pipe.
For galvanized propane pipes, it is also important to consider the size of the pipe. The pipe diameter should be large enough to accommodate the amount of propane that you will be using. If you are not sure about the size of pipe that you need, then you can consult with a propane supplier or a plumber.
Tips for Maintaining a Galvanized Pipe Propane System
Galvanized pipe was once a popular option for propane systems, but it is no longer allowed by most codes.
If you have an existing galvanized pipe system, there are several things you can do to maintain it.
- Keep the area around the tank clean and free of debris.
- Check the condition of the pipes regularly, looking for any signs of rust or corrosion.
- When connecting or disconnecting the propane tank, always use a wrench to avoid damage to the pipe threads.
- Never use a torch or other open flame to thaw frozen pipes.
- If you must make repairs to the system, always consult a qualified technician. Attempting to repair the system yourself could be dangerous.
- Have the system inspected by a qualified technician at least once per year.
By following these tips, you can help prolong the life of your galvanized pipe propane installation.
It is important to remember that this type of system has a limited lifespan and will eventually need to be replaced. When the time comes, get in touch with a professional to discuss your options.
FAQs:
2. How long does galvanized pipe last?
The answer depends on a number of factors, including the thickness of the zinc coating, the quality of the iron pipe, and the environment in which the pipe is used.
In general, the galvanized pipe can last for decades. The zinc coating protects the iron pipe from rust and corrosion, and the iron pipe itself is quite strong.
If the zinc coating is damaged or if the iron pipe corrodes, the galvanized pipe will need to be fixed. With proper care and maintenance, galvanized pipes will be able to provide many years of service.
4. Can I use a black pipe for propane?
While you can technically connect propane to a black pipe, it is not the best idea. This is because the pipe is made of steel, and its inside is coated with galvanizing to prevent rust.
Over time, this galvanizing can flake off, and if enough flakes end up in your propane tank, it can cause problems with your appliances.
The galvanizing can give your propane a metallic taste. For these reasons, it is better to use a different type of pipe for your propane line.
Can I replace galvanized pipe myself?
While it is possible to replace galvanized pipe yourself, it is generally not recommended. The process is fairly complex, and there is a risk of causing damage to your home if the replacement is not done correctly.
Galvanized pipe is also notoriously difficult to remove, so unless you have significant experience with plumbing, it is best to leave the job to a professional.
If you do decide to replace the pipe yourself, be sure to follow all instructions carefully and turn off the water to your home before beginning work.
Can galvanized steel make you sick?
Galvanized steel is covered in a thin layer of zinc to protect it from corrosion. However, when welders work with galvanized steel, the heat of the welding process can vaporize the zinc coating, resulting in the release of zinc oxide fumes.
These fumes can be harmful if inhaled and may cause metal fume fever, a condition that causes flu-like symptoms, including fever, chills, and chest pain. In severe cases, metal fume fever can lead to pneumonia or kidney damage.
Therefore, it is important for welders to take precautions to avoid inhaling zinc oxide fumes when working with galvanized steel.
Final Thoughts
So, can you use galvanized pipe for propane? The answer is yes, but with a few caveats. Galvanized piping should not be used in areas where there is high moisture or corrosive elements, as this will damage the coating and eventually lead to leaks.
Because galvanizing creates a non-conductive barrier, it’s important to make sure that any electrical wiring passing through the piping is properly insulated.
If you’re still unsure whether the galvanized pipe is right for your propane system, consult with a qualified professional.
At the end of the day, using galvanized pipe for propane can be a cost-effective way to keep your home warm during cold winters.
Just make sure you take all the necessary precautions. We hope you found this information helpful. Thanks for reading.
