If usability of the pipe is no issue, and you have the safety equipment, I suppose you could clean it off with soap, and then rinse it with HCl, and then scrape at it for a while. Alternatively, you could use liquid nitrogen to flash freeze it, and then strike it with a hammer. I have never personally tried either method, would use extreme caution in whatever manner you choose. This is purely theoretical, any damage you inflict is your own fault, do not attempt the above.
Carbon Steel pipe is stronger than stainless steel pipe as there is more iron in the carbon steel. However, the application depends on the purpose the pipe is being installed. Stainless is of course capable of being sanitized and therefore can be used for food and pharmaceutical uses. Carbon Steel (black pipe) is stronger and cheaper but not sanitary.
There are instances when corrosion occurs at the junction of a carbon steel pipe and a brass valve. This is often the result of a pipe threading failure.
Adding sulphur to steel makes it easier to machine but only in controlled amounts. Too much sulphur and it become brittle and can crumble.
Iron ore is purified with Carbon dioxide and it creates the harder substance steel
There are several instructional videos on YouTube that show how to make a glass pipe out of blown glass. It is very dangerous to do without the proper safety equipment.
more brittle
Illinois makes steel pipe and tubes
California makes steel pipe and tubes
Because hard steel would be brittle and break.
brittle
it is ductile. For hardened stainless steel it gets less ductile, but not brittle.
China is a large country to export steel pipe, if you want to buy steel pipe, you can import from China.
Yes
It will be lowered with the result that the steel becomes more brittle.
Mexico exports steel pipe and tubes
Australia makes steel pipe and tubes
Brazil makes steel pipe and tubes
