Water and gas require pipes to supply residential homes and businesses. Gas supplies power to stoves, water heaters, furnaces and other devices. Water is essential and obvious. The two most common types of steel pipe used to carry water and gas are black pipe and galvanized pipe. So, what is the difference between black pipe & galvanized pipe. Confusion is common among home owners, and even some professionals, as to where to use these steel pipes and under what circumstances.

Galvanized Pipe
Galvanized steel pipe is covered with a zinc material to make the steel pipe more resistant to corrosion. The primary use of galvanized pipe is to supply water to homes and buildings. The zinc also prevents the buildup of mineral deposits that can clog the water line.
Black Pipe
Black steel pipe is different from galvanized pipe because it is uncoated. The dark color comes from the iron-oxide formed on its surface during manufacturing. The primary purpose of black steel pipe is to carry natural gas into homes and businesses. The pipe is manufactured without a seam, making it a stronger and safer pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.
In brief:
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.

It is obvious that changes in the current patent system, introducing clearer criteria for protection, in the broad scope of bringing to court on dubious patents describing obvious or already powerful technologies, harm. 'This reform is good for business and good for the inventor,' says Levant. Vladimir Meshcheryakov, adviser to Gorodissky & Partners, in turn, believes that the changes for domestic applicants are very procedural in nature and will not significantly affect the protection system in the United States. The innovation, in his opinion, harmonizes US legislation with regard to other countries and acquisitions, especially for foreign companies diversity in patent law. Previously, when wishing to file a patent for an invention in the US, they were faced with the protection that was obtained in that only the author of the invention could apply, not the company. To no lesser extent, this change has political significance, since it changes the accession enshrined in the US Constitution, which already at the frequency of frequencies suspends the power of the US from establishing this innovation.
Also, an increase of 10% on import steel pipe will be in effect Monday, 3/21. Please call your Merfish United representative for more information or to place orders now.
Competition for raw materials, like steel, is increasing from the OCTG sector and other finished goods manufacturers. Increased consumer demand and a decreasing global supply of critical materials like nickel, zinc, and iron ore drive rising input costs. These conditions mainly stem from supply chain disruptions out of Ukraine and Russia, where steel and oil exports are either stopped due to sanctions or unable to operate because of wartime conditions.
European steelmakers are cutting back operations as energy prices skyrocket, despite steel trading at near-record levels. There are new limitations on gas imports from Russia that fuel electrical power stations, which power electrical furnaces that produce steel. The high cost of energy is causing producers in Europe to scale back or stop production, sending ripple effects through an already tight global supply due to the loss of steel output from Ukraine.
As the market adjusts, steel supply slack may be picked up by China for certain manufacturers outside of the U.S., in India, and by new facilities are coming online here in the country but will take time to catch up.
Also, due to the loss of Russian oil and gas in the market, oil production in the U.S. market is picking up and may see an even more significant increase soon. Oil country tubular goods are milled using the same rolled-steel coil that plumbing pipe and other tubular products use, and the increased competition for these raw materials may mean longer lead times from mills.
Gas prices are rising, which increases shipping and freight costs, including trains, trucks, ships, and barges.
For now, global supply is becoming more limited as the demand for remaining hot-roll coils and raw materials increases. Manufacturers of finished goods, including steel pipe mills, will continue to see a rise in input costs.
