Running black iron pipe for propane use may appear to be a difficult process, and you will pay a professional to complete it. The truth is that this is a great do-it-yourself project if you have the necessary tools and some basic pipe fitting knowledge.
What kind of propane pipe is used?
- Black pipes are tough and long-lasting. Black steel pipes, black iron pipes, and black malleable pipes are some of the other names for them.
- Natural and propane gas is transported from the street or a tank to the home using this device.
- It’s available in lengths ranging from 2 inches to 10 feet, with diameters ranging from 1/4 inch to 2 inches.
Is it possible to use black iron for a gas line?
This is where the Universal Product Code (UPC) comes into play.
There are precise guidelines for when black iron gas pipes can and cannot be utilized.
It can constitute a severe safety issue if utilized in the wrong spot.
Simply put, black iron pipes can be utilized for gas under your house, in the crawl space or basement, inside the walls, or in the attic – basically anywhere it isn’t exposed to the elements or the earth (moisture).
This is due to the absence of an anti-corrosion coating.
For gas lines that must be run underground, a specific black pipe coated with a particular plastic compound that keeps moisture out should be used.
This is so that it can be distinguished from underground water lines, as well as because the plastic coating preserves the pipe better than a galvanized coating.
However, make certain that any exposed pipes are covered with pipe-wrap glue and 10mil pipe-wrap tape.
This includes the joints as well as any marks on the coating caused by pipe wrenches or other tools.
The adhesive is necessary because it fills up any small gaps left by the tape operation.
Once the gas pipe (also known as the main line) emerges from the earth (also known as the main line), “It can be wrapped for a while longer, but it must then be galvanized.
I’m not sure why this is the case.
It is also permissible to use black iron if it has been galvanized (which is essentially a special coating) “(“paint”)
When piping in their gas meters, PG&E frequently does this.
Other rules apply to where gas lines may and cannot be run, as well as the minimum sizes required to supply gas to all of your fixtures/appliances and the materials that can be utilized, but those are topics for future articles.
The most important thing you should take away from this post is to ensure that the plumber working on your gas lines is a professional.
What is the most typical material for propane piping in the home?
Many households in the northern half of the country will have to turn on their heating systems at the beginning of October. Natural gas is one of the most cost-effective and efficient fuels for a furnace or boiler. With its benefits come questions about safety and obligations for homeowners. It is your role as a home inspector to assist in the detection of flaws that may jeopardize the safety of residents in natural gas-powered homes. We’ll go through some of the fundamentals of gas piping inspection.
The gas supply line, also known as the building line, is the plumbing that runs throughout the house. Individual appliances are served by branch lines. The branch line finishes in a drop line, which is a vertical pipe that drops down from an overhead branch line to the appliance. If it carries gas up to an appliance from a branch line below the appliance, it’s called a riser.
A sediment trap or dirt pocket, commonly referred to as a drip leg, is normally present at the appliance connection point and consists of a nipple and a cap. This pipe extension, which is normally at least 3 inches long, is designed to catch any water or foreign material that may be present in the gas before it enters the appliance. The solids and liquids fall into the pocket, which is just a gravity mechanism.
The homeowner is normally responsible for the pipework downstream of the gas meter. The gas company is normally responsible for the piping upstream of the gas meter, as well as the meter itself.
Steel, copper, and brass are the most popular materials for gas piping. In some cases, galvanized steel, copper, brass, or CSST (Corrugated Stainless Steel Tubing) can be used, but copper is prohibited by some utilities. Copper is widely used in different parts of the world. You should be aware of what is considered acceptable in your neighborhood. Black steel piping with malleable iron or steel fittings is common. In other cases, galvanized steel is also used.
Flexible connectors are allowed to be used to connect appliances to gas pipelines. A shut-off valve must be installed at the rigid piping connection. This valve must be located in the same area as the appliance.
Accessible and three or six feet long: The flexible connectors cannot pass through walls, floors, or ceilings, and they cannot be hidden. Except for gas stoves and laundry dryers, the flexible connector length is normally limited to 3 feet. 6 feet is usually allowed for these equipment. Using nipples to splice or join connectors is frequently forbidden. Flexible connectors are only allowed in some jurisdictions for gas stoves, dryers, outdoor barbecues, and other semi-portable equipment. Flexible connectors may be prohibited on gas furnaces, water heaters, space heaters, and other similar appliances. Flexible connectors are more likely to be utilized on all appliances in earthquake-prone areas because they give some protection against gas piping leakage or rupture during an earthquake. To find out what is and isn’t permitted in your area, consult your local gas code.
The use of white thread seal tape (often referred to as Teflon tape) as a connecting compound for steel gas piping is not recommended. Cutting oils on the pipe threads from the manufacturing process may hinder the tape from sealing. Yellow thread seal tape is permitted in some regions. Pipe dope is favored and may be the only option available. You might wish to double-check with the gas company. Inquire about whether any piping installations with thread seal tape of any color should be reported as a defect.
Although certain exceptions exist, most appliances should have a shut-off valve nearby.
The use of gas piping as a grounding mechanism for the electrical service is prohibited by most authorities. In many countries, however, bonding the gas piping to the electrical grounding system is required. This is often accomplished by connecting the gas pipe to the supply water piping (assuming it is grounded) near the water heater. We want to keep the gas piping at zero electrical potential by attaching it to the grounding system to prevent an electrical potential building within it that could lead to arcing, which could ignite gas.
All of these issues have the potential to result in gas leaks and explosions.

Is galvanized pipe suitable for use with propane?
YES… sort of… perhaps.
The National Fuel Gas Code does not ban galvanized piping in gas installations, unless a current edition has amended this.
Yes, zinc flaking is a worry, but it’s no more so than copper sulphite resulting from reactions between contaminants in the fuel and copper in the system.
This is why each appliance requires a properly placed sediment trap (also known as a drip leg).
Why are gas lines made of black pipe?
Pipes are needed to supply water and gas to houses and businesses. Stoves, water heaters, furnaces, and other appliances run on gas. Water is both necessary and obvious. Black pipe and galvanized pipe are the two most prevalent types of steel pipe used to transport water and gas. Homeowners and even some professionals are often perplexed as to where and when to use these steel pipes.
Galvanized steel pipe has a zinc coating applied to it to make it more corrosion resistant. Galvanized pipe is mostly used to bring water to homes and structures. The zinc also helps to prevent mineral deposits from clogging the water line.
Because it is uncoated, black steel pipe differs from galvanized pipe. The black color is due to the iron oxide that formed on the surface during production. Black steel pipe’s principal function is to transport natural gas into homes and businesses. The pipe has no seams, making it a stronger and safer pipe for transporting gas. Because black steel pipe is more fire resistant than galvanized pipe, it is also utilized for fire sprinkler systems.
Because of the galvanized coating, you should not use galvanized pipe for gas. Galvanized steel bits will flake off over time and block your gas regulators and burner units.
If you mix galvanized and black iron, corrosion will be accelerated where they come into contact.
What is the purpose of black pipe?
40th Schedule Galvanized or black steel pipes are widely used for gas and water lines, but they can be utilized for a variety of other applications as well. Do you have a creative streak? Find out more about galvanized pipes, black steel pipes, and DIY steel pipe projects.
What is Schedule 40 Pipe?
Pipe wall thicknesses for various uses have been specified by the American National Standards Institute. Schedule 10, Schedule 40, Schedule 80, and Schedule 160 are among them. The most common pipe thickness used in construction is Schedule 40. This standard strikes the perfect combination between affordability, strength, and installation convenience.
Schedule 80 or Schedule 160 pipes may be necessary if the pipes are exposed or if high-temperature or high-pressure water or gas must be transported. Light-duty applications are assigned to Schedule 10.
What is Galvanized Pipe?
Galvanized pipe is a zinc-coated steel pipe. The addition of zinc to the pipe improves its resistance to corrosion and mineral deposits, extending its life. For more than 30 years, galvanized pipe has been used as a water supply line material in houses and businesses. It’s also a good choice for sewer piping.
Aside from water and sewer lines, galvanized pipe is used for fences, railings, scaffolding, and farm irrigation systems. It’s best used in huge construction projects and has a 40-year lifespan.
Galvanized pipe corrodes faster than copper and PVC pipe, despite the zinc covering. Because the zinc clogs the line as it starts to flake, it can’t be utilized for gas lines. A galvanized steel water pipe can also explode due to flaking zinc. Lead is also present in this substance, which can contaminate drinking water. Galvanized pipe is more expensive than standard black steel pipe because of the zinc added to it.
What is Black Steel Pipe?
Water and natural gas are transported from their sources to homes and businesses using black steel pipe. Because of its high heat resistance, black pipe is often utilized in fire sprinkler systems. Black pipe can also be seen in heat exchangers, where it transfers heating and cooling water. Drain lines and heating pipes are two other applications that come to mind. Because black steel pipe rusts fast, it is not ideal for transporting drinking water.

Is black pipe made of iron or steel?
We started selling a selection of black iron pipe and fittings on our website earlier this year. Since then, we’ve discovered that many customers are unaware of the benefits of this fantastic material. Simply said, black iron piping is one of the greatest gas line solutions available. It’s sturdy, simple to install, corrosion-resistant, and maintains an airtight seal. Corrosion is slowed by the black coating.
Black iron pipe was once common in water lines, but since the introduction of copper, CPVC, and PEX, it has become much more common in gas lines. It’s a fantastic alternative to gas for two reasons. 1) It is sturdy, and 2) it is pretty simple to assemble. Black malleable iron, like PVC, uses a system of tubing and fittings that are joined with compounds rather than welding. Black iron pipe is really built of a low-grade “mild steel” composite, despite its name. This makes it significantly more resistant to corrosion than ordinary cast iron piping.
