![]() The first use was probably by ancient agriculturalists to divert water from rivers and streams into the fields. Pipes have been used for thousands of years. Steel pipes can also be found in automobiles, refrigeration units, heating and plumbing systems, flagpoles, street lamps, and medicine to name a few. This makes them ideal to be used in the bicycle frame manufacture. What interesting about steel pipes is that they can be both strong and lightweight. They are also employed in construction to protect electrical wires. Since they are strong, they are used underground for transporting water and gas throughout cities and towns. Steel pipes can be found in a range of places. Its versatility makes it the most often used products in the steel industry. The first methods for producing steel pipes were introduced in the early 1800s, and they have steadily evolved into the modern processes today.Įach year, millions of tons of steel pipe are produced. Then it is made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. In both methods, raw steel is first cast into a more workable starting form. Steel pipes are produced by two distinct methods that would eventually result in either a welded or seamless pipe. 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. Other uses of black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. In addition, black steel pipes are also used in oil and petroleum industries for piping large quantities of oil through remote areas. 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. Black steel pipes tend to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well.Black steel pipes have a variety of use thanks to their strength and needs for little maintenance. ![]() In view of this, transport gas by galvanized pipes is dangerous so it is often used in carrying water.īlack steel pipe, on the other hand, is not suitable for water transport. Galvanized pipe has zinc on the surface so the mineral will flack off as time goes by and block the pipe. 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. The main difference between steel pipe and galvanized pipe lies in the surface. Since it has a dark color surface which is formed by iron oxide during the manufacturing process, it is called black steel pipe. Black iron pipe is also most often use in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage. ![]() Black iron pipe is used to transport natural and propane gas in residential applications.īlack 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. Galvanized pipe fittings should not be used with gas applications.īlack pipe fittings (black malleable iron fittings) are used to make connections to black iron pipe. The main advantage of using galvanized fittings is their superior rust resistance when compared to black and copper fittings. While they work best with cold water lines, they may be used with hot water as well. Galvanized pipe and fittings may be used in most applications with the exception of underground lines. Galvanized pipe fittings are used for countless outdoor and industrial applications because of the material's ability to protect against corrosion and salt. Galvanized pipe is mainly used for carrying water to supply home and commercial buildings it may also serve as scaffolding frames because of its rust prevention. Galvanized pipe fittings are covered with a layer of zinc which makes these fittings have higher ability of corrosion protection and help to prevent the accumulation of mineral deposits that will block the pipe. For transportation, black steel pipe tend to erode more easily than galvanized pipe and therefore it is more suitable for transporting gas and galvanized pipe is fit for carrying water instead of gas. As a result galvanized pipe is more durable. Both black steel pipe and galvanized pipe are made of steel, however, galvanized pipe has a zinc coating while black pipe does not. ![]() Black steel pipe fittings and galvanized steel pipe fittings are the two most common kind of pipe applied to transport liquid and gas.
