Steel is one of the most common types of metal used by millions of people worldwide. If you have always wondered how it’s made here is information to guide you though. It’s important that you know that the entire process involves three steps: the conversion of the raw steel to functional form, the formation of the steel in a continuous or semi continuous production line, and the cutting and modification of the steel to fit the needs of the customer.
Conversion of the raw steel
This is also known as the ingot production. Here molten steel is made by heating coke and iron ore in a furnace. Carbon is then removed by pumping a lot of oxygen into the liquid. The molten steel is then poured into thick walled iron molds where it cools into ingots. To form flat products such as plates and sheets, the metals are shaped between large rollers under high pressure.
To produce blooms, ingots are passed through a pair of grooved steel rollers that are usually stacked. Before the blooms are made into pipes, they are processed further. They are converted into billets by being put through more rolling devices that are long and narrow. This process allows sufficient cuts without stopping the manufacturing process. Once they are done, the billets are stacked and eventually become seamless pipes.
Billets and skelp are used to make steel pipes. As the spool of steel is unwound, it’s heated and passed through a series of grooved rollers. As it passes, the rollers cause the edges of the skelp to curl together forming an unwedded pipe. After this, the manufacturing company passes welding electrodes sealing the two ends of the pipes together.
The welded seam is then passed through a high-pressure roller that results in the formation of a tighter weld. The professionals then cut the pipes into different sizes and stacked for further processing.
Here the pipes are put through a straightening machine. It’s also common for them to be fitted with joints connecting two or more pieces of pipes. The pipes can be joined using different types of joints, but the most common is the threading joint. Here tight grooves are cut into the end of the pipe. Once the process if over the pipes are sprayed with a light coating of protective oil.
This is the process of making steel pipes. To get the most from the pipes, you should buy those that are of high quality and made using the best method.
