Can I use stainless steel for gas pipe?
Piping materials
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.
PE piping is the only approved plastic piping under NFPA 58, Liquefied Petroleum Gas Code, and is commonly used in the piping of liquefied petroleum gases (vapor LP-Gas).
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.
If you have good soil drainage, use either copper pipe or unwrapped black iron. If you have poor soil drainage, use only copper. If you use wrapped black iron, the tape will eventually permit moisture to creep between the tape and the pipe and will trap that moisture against the pipe. This accelerates rusting.
Argon is the simplest gas for TIG welding stainless steels and nickel alloys. It produces a stable welding arc and is suitable for all grades of stainless steel. However, as the thickness of the material increases, fusion problems can arise, due to the arc being more viscous and more difficult to manipulate.
Never use dissimilar metals when installing the plumbing system, including fasteners, hangers, bolts, screws, etc. Even a screw in a dissimilar metal can cause accelerated corrosion around the screw.
Incompatible Materials: Increased risk of fire and explosion on contact with: oxidizing agents (e.g. peroxides), halogens (e.g. chlorine). Not corrosive to: aluminum alloys, carbon steel. Hazardous Decomposition Products: None known.
Flexible copper is often used for LP gas connections and piping.
Black iron is the most common material used to make gas pipes, both in interiors and exteriors. The material is strong, heat resistant and can fit together to form an airtight seal.
Black steel pipe is uncoated and made without steam, and therefore, it is widely used for transporting gas like propane and natural gas to residential and commercial building.
Can galvanized steel pipe be used for propane?
So, unless your local codes prohibit it, you can use galvanized pipe for gas. Just be sure to mark your gas lines with a yellow paint to distinguish the galvanized water piping from the galvanized gas pipe. That said, black iron pipe is the most preferred pipe for natural gas.
Corrosion is an aggressive form of rusting and rust to a steel propane tank and metallic piping can be fatal. As steel ages it begins to rust. Some rust is superficial and of no serious concern.
Yellow thread seal tape meets all gas company standards for gas lines of all types, be it butane, propane, or natural gas. It's important to use the right thread seal tape for gas, and the yellow variety is the only safe choice.
Generally, the majority of tanks fall under a ten foot rule with regard to buildings and houses.
Expert Reply: Yes, you will want to use some sort of thread sealer like part # LT37482 or pipe tape like part # A05-0265 on the NPT fittings inside of the MB Sturgis Single Stage Propane Regulator part # 108072.
Aesthetically, there is no difference between the two; in fact, the only way to differentiate between them is to test them chemically. The main difference between 304 and 316 stainless steel is 316 SS has the addition of molybdenum.
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
The most popular grades of kitchen and food quality stainless steel are 304 and 316. 304 is usually used for kitchen appliances and equipment and the most highly used stainless steel. 316 is considered to be more surgical grade and used for cutlery with a smoother finish and prevents certain types of corrosion.
The combination of aluminum and stainless steel causes galvanic corrosion. In order to understand why you shouldn't use stainless steel and aluminum together, we first need to understand how galvanic corrosion works. Galvanic corrosion is the transfer of electrons from one material (anode) to another (cathode).
You do not want to use galvanized pipe for gas because of the galvanized coating. Over time pieces of the galvanized steel will flake off and clog your gas regulators and burner units. Never mix galvanized and black iron or where they touch corrosion will be accelerated.
Will stainless steel cause galvanic corrosion?
What Is Galvanic Corrosion? Galvanic corrosion is the reason connecting carbon and stainless steel can lead to problems. Galvanic corrosion is when one metal causes another metal to corrode and break down.
Why Is Propane Harmful? Propane is an asphyxiant, meaning very high concentrations of the gas can cause suffocation. Exposure to high concentrations can also cause cardiac arrest, unconsciousness, or seizures. Sustained contact with the skin can cause frostbite.
Despite the reputation of some tape products, do not try to “patch” a leaky hose in this manner — it will not protect you. You will notice that propane hoses have a 300 psi rating. Duct tape, electrical tape or clear packing tape does not meet this requirement.
- Don't use or store portable propane tanks in basements or living spaces.
- Properly secure portable propane tanks when transporting.
- Do not leave portable propane tanks in cars or closed vehicles.
- Secure temporary tanks when used for building heat, hot water, or cooking.
In contrast, black steel pipes are uncoated and made without steam. Therefore, it is widely used for transporting gas like propane and natural gas to residential and commercial building. Black steel pipes can also be used for fire sprinkler system since it can prevent fire better than galvanized pipes.
If cylinder is laying down and leaks, then liquid propane would come out and liquid propane expands 270 times to vapour. Therefore, you would have 270 times bigger leak.
PEX is a relatively uncommon material for in-home gas lines, but that doesn't mean it can't be used. It is more commonly used for external underground gas lines that deliver large amounts of gas to serve a whole neighborhood.
Copper and copper alloy pipe shall not be used if the gas contains more than an average of 0.3 grains of hydrogen sulfide per 100 standard cubic feet (scf) of gas (0.7 mg/100 L).
copper is safe for LP, but not recommended for natural gas. due to "concerns over corrosion and flaking of copper tubing, copper is not allowed for use on natural gas work in some localities" (see reference)

- Flexible Corrugated Stainless Steel Tubing (CSST): CSST is another popular gas piping option and can be used in tighter spaces because it's more flexible. ...
- Galvanized steel: ...
- High-Density Polyethylene Piping (HDPE):
Can you run propane line above ground?
Exterior piping may be either buried or installed aboveground and shall be well supported and protected against mechanical damage. Underground piping shall be buried not less than 18 inches below the surface of the ground unless otherwise protected.
Polyethylene gas piping systems are specifically engineered and certified for the underground environment.
Standard rubber vacuum or heater hose should never be used in fuel applications.
Can I use SharkBite fittings for anything other than potable water and radiant heating (e.g, air, gas, oil, etc.) applications? No. SharkBite fittings are only certified for potable water & radiant heating installations.
For any part of a propane gas service line, only use approved materials and fitters. Using materials such as PVC, rubber hose and flex lines for the gas service line are all illegal.
The 20-pound cylinders are made from a specific type of manufactured carbon steel, with grain structures that can be seen under a microscope.
Since LP gas is stored under pressure in a liquified state, even a small leak can create the possibility of significant gas explosion and fire.
- Propane produces fewer BTUs per gallon than oil heating.
- Propane-burning equipment often costs more to purchase than heating oil-based systems.
- Propane is combustible in air, so precautions are needed to operate the equipment safely.
However, LP gas or natural gas can become dangerous if the gas leaks out of a tank or supply line. If enough gas builds up inside a building, it can cause a powerful explosion if the gas is ignited.
The correct type of Teflon tape for gas fittings has a yellow color and is identified in the packaging as manufactured specifically for gas pipes and connecting gas lines. This type of tape is known as gas-rated Teflon tape. It is designed to accommodate all gas lines, including natural gas, propane and butane.
What do you use to seal propane fittings?
PTFE (Teflon) tape/pipe dope is only necessary on pipe thread fittings. This is because pipe threads are tapered - as you tighten the fitting, the threads bind together and deform slightly to create a seal. The pipe tape/dope helps lubricate the threads and make a better seal.
Propane Line Depth Requirements
Depths range from 12 to 18 inches underground, depending on vehicular traffic. The reason for this depth requirement is simple - the earth, dirt, sand or whatever is covering the line needs to adequately protect the underground gas line from damage.
100-pound propane tanks
Still, when placing a 100-pound propane tank on your property, you must adhere to the following requirements: The minimum distance from the opening of a building is 3 feet. The minimum distance from any source of ignition is 5 feet.
Please Note: We do not recommend having a hose above 20 feet in length as it might cause a decrease in pressure.
Use whatever you want but rest assured white ptfe is approved for gas and other flammable liquids as a thread sealant.
Consider insulating your tank – Insulating your tank with an approved propane tank heating blanket can also prevent pressure problems and keep your tank from freezing. Never use a space heater, hot water, or a blowtorch to heat your propane tank!
Bonding directly connects the propane tubing to your home's grounding electrode. In the event of a lighting strike, bonding reduces the risk of an arc forming between your propane tubing and other metal objects. Such an arc could cause a gas leak by creating a pinhole in the CSST.
Steel pipes can be used above ground as long as corrosion due to the environment and the conveying gas is of no problem. Steel pipes and copper pipes are the most common materials used inside buildings.
Steels are not subject to significant corrosion in natural gas environments, regardless of the concentrations of other contaminants, unless liquid water is present.
CSST Pipe. 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.
Can you use stainless steel on a gas grill?
Don't use it on a grill (or in a microwave). Most stainless-steel pots and pans are meant to be used at moderate heat and technically can withstand up to 500 or 600 degrees Fahrenheit. A grill has the potential to get much hotter, which can damage and warp the metal.
PVC pipes will work well for natural gas lines and water supply. They are generally available in sizes of 10 feet and 20 feet and come in varying diameters. The size ranges from ½ inch to 6 inches to choose one depending upon the purpose.
Benefits and applications of stainless steel
The main pipes used in the offshore Oil and Gas Industry are Duplex 2205 (22% Chromium, 5% Nickel) and 2507 (25% Chromium, 7% Nickel); and Super Duplex 2507 which has higher corrosion resistance.
Common causes of stainless steel corrosion include chlorides, hydrochloric acids, sulfuric acids, iron or carbon steel contact, and high temperatures. There are over 150 grades of stainless steel, and some are more prone to corrosion than others.
Studies show that some of the ions which are released from stainless steel devices are able to destroy or damage enzymes and proteins, in addition to causing allergic reactions. Stainless steel alloys can contain nickel, chromium, molybdenum, iron, carbon and various other metals.
Black steel pipe is uncoated and made without steam, and therefore, it is widely used for transporting gas like propane and natural gas to residential and commercial building.
So, unless your local codes prohibit it, you can use galvanized pipe for gas. Just be sure to mark your gas lines with a yellow paint to distinguish the galvanized water piping from the galvanized gas pipe. That said, black iron pipe is the most preferred pipe for natural gas.
PEX and PE are flexible and rated for much higher pressure than most gas lines, so they meet those basic requirements. However, they are made of a soft material that nails, rodents, and other things could potentially damage. This is why either may not be approved for residential gas line usage in your area.
Corrosion is an aggressive form of rusting and rust to a steel propane tank and metallic piping can be fatal. As steel ages it begins to rust. Some rust is superficial and of no serious concern.
Thick cuts of meat do well on both cast iron and stainless steel. Chicken is easy to grill on either type of grate. However, if you're grilling a thinner, more delicate cut of meat, you might need some direct contact with the cooking surface to give it more flavor.
Does stainless steel rust?
Some types of stainless steel are more prone to corrosion than others, depending on the chromium content. The higher the chromium content, the less likely the metal will rust. But, over time and if not maintained correctly, rust can and will develop on stainless steel.
