Pumping through the transmission lines Once it’s processed, natural gas pipeline operators ship the natural gas through large transmission pipelines to the people who need it. Compressor stations are loed along the pipeline route every 65 to 160 km. Large compressors similar to jet engines (with up to 36,000 horsepower) move natural gas through the pipeline at around 40 km an hour.
Corrosion Control in Oil & Gas Pipeline Chemical Injections Corrosion inhibitor: Basically meant for CS pipelines, forms a layer of film on the surface and protects the core pipe from corrosion attack. Batch injection or continuous Scale Inhibitor: Prevents scale formation in the pipelines by
Metallic pipe installed underground requires additional and costly materials to protect the pipe. Polyethylene gas piping systems are specifically engineered and certified for the underground environment. To provide a true underground gas piping solution, Gastite
15/6/2016 Biogas and natural gas are both produced by the breakdown of organic material by bacteria that metabolize the organics into primarily methane and carbon dioxide. Biogas and natural gas can include impurities such as hydrogen sulfide, mercaptans, and others (alkanes, nitrogen, oxygen and trace amounts of other gases such as helium).
Plastic Gas Pipe 1. Do not use plastic gas pipe and tubing in or under buildings or within slabs. Use plastic pipe, tubing, and fittings only underground. 2. You may use plastic gas pipe under patio, walkways, and driveways if the pipe is buried deep enough. See
Polyethylene (PE) gas piping is the most widely used plastic piping material for the distribution of natural gas. PE has a well documented inertness to both the external soil environment and to natural gas. Extensive testing and over 45 years of successful field
HDPE natural gas pipes have the following advanPE100 ISO9001es: Corrosion resistance: HDPE is an inert material that is resistant to various chemical media. No leakage: HDPE pipe is connected by electro fusion and its interface strength is higher than that of the pipe itself. Puhui Pipe manufacturer in China
The material of choice for most above ground installations of natural gas piping is ASTM A53/A53M, black HDPE, Schedule 40, Type E or S, Grade B. carbon HDPE pipe. HDPE piping is used for systems operating in excess of 1,000 psig (6,900 kPa) and delivering natural gas to loions in excess of 300 miles from the last compressor station.
In my admittedly limited experience working with pluers, natural gas pipes are typically made from galvanized HDPE for interior work, or from black HDPE pipe for underground. Last leg fittings and tubes which connect the stub outs to various appliances are sometimes made from copper and brass.
MDPE, being more flexible, is the material of choice for the underground gas piping appliions, and it is the type we sell at PexUniverse. HDPE pipe is less common is the gas industry and usually is intended for non residential appliions with high pressures (up to 125 psi).
Gastite provides corrugated stainless HDPE gas piping for propane and natural gas in commercial and residential appliions. Gastite flexible gas piping cuts labor cost when
9/9/2010 For natural gas, the pipe of choice and code, in most cases is schedule 40 black HDPE pipe, that has been used for about 100 years. The underground black pipe of today has a factory applied plastic coating to stop corrosion. Don''t fall out of the saddle on that

The 3/4 in. IPS size Yellow Poly Gas Pipe Transition Fitting allows you to transition from MDPE Yellow Poly Gas Pipe to metal pipe. One end of this Transition Fitting is plain 3/4 in. IPS poly gas pipe that will connect to your run of poly pipe using one of the 3/4 in. HOME FLEX Underground fittings such as the Coupler, Tee or Elbow.
Underground natural gas pipelines present a different set of hurdles for technicians. Even on bridge utility projects, certain lengths of a pipeline eventually go underground at the base of the bridge. For underground appliions, HDPE is the industry standard.
26/3/2015 Black pipe will disintegrate over period of time when used underground thus leaking gas. You must use pipes that are certified for underground use ( mostly plastic or coated ) Maymybonneliveforever wrote: ↑ I''m also thinking of doing this project, what about using black iron underground and painting it yellow.
Decomposition produces methane, (CH4), and when trapped underground we call it natural gas. Natural gas is odorless, so a trace of mercaptan, (CH4S) is added to make it detectable. Reacting natural gas with steam separates the hydrogen and a second reaction, this time with air, results in
However, for single underground gas line appliions where the new gas line is starting directly from the gas meter, this simple chart provided by NW Natural can be used as a good resource. Hot Tip: When it comes to Firepits, always err on the high side when sizing the underground gas line!
natural gas pipe. Made of high quality PVC and synthetic materials, it is soft and elastic, safe and reliable, with good pressure resistance, good weather resistance and excellent sealing. High quality raw materials produce no odor, strong bending ability and strong durability.
1/12/2013 I''m converting a portable generator to run on natural gas. I need to tap into my gas line in my home, run the line through the basement wall and then underground for about 25 feet. From there, the line will need to go vertical and rise above the ground level to around 16 to 24 inches where I plan on installing a secondary valve and an elbow with a simple pipe plug.
