Differences between seamless black steel pipe and black iron pipe
Black steel pipes are made of steel that has not been coated with a substrate such as zinc or paint. Since it has a dark color surface that is forms by iron oxide during the manufacturing process, it is called black steel pipe.black iron pipe is actually made of a low-grade "mild steel" compound. This gives it much better corrosion resistance than traditional cast iron piping.
Steel pipe will have a very fine feel to it and almost be cool to the touch. It won't scratch as easily as black iron pipe, but that doesn't meant it can't be damaged by a wrench or hammer while working around it. Black iron pipe is course and grainy and will feel the same at room temperature. Black iron pipe will also flake if it is handled a lot.
The main problem with black iron pipe--especially in the home--is leakage at connector spots. It requires a lot of work to fix these leaks, which is why many people no longer use black iron pipes. Steel pipes do not have that problem because it is most often welded.
Steel pipe will usually cost about 20 percent more than black iron pipe, but it does a better job of saving resources in the long run by being more energy efficient. Its durability and cost are part of the reasons that use of steel pipes for large industrial jobs has grown in the United States.
What are black steel pipes used for?
Black steel pipes have a variety of use thanks to their strength and needs for little maintenance. They tend to be used for transporting gas and water to rural areas and urban areas or for conduits that protect electrical wiring and deliver high pressure steam and air. In addition, black steel pipes are also used in oil and petroleum industries for piping large quantities of oil through remote areas.Other uses of black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. However, black steel pipes are never used for transporting potable water due to the fact that they tend to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well.
What are black iron pipes used for?
black iron piping is one of the best options for gas lines that exists. It is strong, easy to install, resists corrosion, and maintains an airtight seal. The black coating helps prevent corrosion.Black iron pipe used to be found in water lines, but has been much more popular for gas since the advent of copper, CPVC, and PEX. It is a great option to gas for two reasons.( 1) It is strong, and (2) it is relatively easy to put together. Just like PVC, black malleable iron uses a system of pipe and fittings that fit together with compounds instead of welding. Despite its name, black iron pipe is actually made of a low-grade "mild steel" compound. This gives it much better corrosion resistance than traditional cast iron piping.
In simple terms,black iron pipe is used to transport natural and propane gas in residential applications. Black steel pipe is manufactured as seamless which makes it a better type for gas transportation and fire sprinkler systems since it can prevent fire better than galvanized pipe.
