In piping, there are numerous types of stainless steel used. Stainless Steel Pipe Fittings are the second most commonly used commodity in process industries after carbon steel due to its outstanding corrosion resistance property. Alloy steel with a maximum carbon content of less than 1.20 percent and minimum chromium content of 10.5 percent is stainless steel (SS).
The SS Pipe Fittings have outstanding corrosion resistance and good ductility. Owing to the formation of non-reactive chromium oxide (Cr2O3) film, which adheres tightly to the surface of the metal, stainless steel becomes corrosion resistant. This film serves as a shield against corrosion and protects metal.
Oil and Gas
In the oil and gas industries, technology plays a significantly significant role. Over the past few years, the need for corrosion-resistant piping has grown as the depths we are searching for oil deepens and more strain is put on the stainless steel duplex and super duplex pipes we use. Such harsh conditions can be extremely corrosive and the pipes can quickly break and become unusable for deeper levels if the damage was left unchecked.
Many of the nuclear reactors we use today use heat water to create steam, which is then used to spin turbines that provide us with electricity, and due to the cooling requirements, most of them are located near the coast. As such, all of the water that is pumped in to cool down these reactors is from the sea, and the corrosive nature of seawater needs to be immune.
LNG (liquid natural gas) is gas that for the sake of transportation has been temporarily transformed into a liquid form. To make it simpler and easier to ship, the volume is significantly reduced. In certain cases, it is not feasible or cheap enough to transport natural gas through pipelines to be worth the expense, which is why it is instead transported in liquid form in cryogenic sea vessels and road tankers. As such, to deliver natural gas to parts of the country or world that are difficult to access, it is important to have the right piping that provides secure and economical LNG transport.
The removal of salt and other minerals from a water supply is desalination. This is achieved to turn water into fresh water that is ideal for use or even irrigation by humans. Salt is generated as a by-product in most cases, and desalination is used on many submarines and ships. Desalination is usually spoken about today when seeking to bring fresh drinking water to regions of the globe where it is difficult. In general, saltwater and metals do not mix very well, hence the importance of having piping that is able to withstand the natural corrosive properties of salt water in the desalination industry.
Mining and Minerals
The method of removing minerals from the earth is mining. The materials protected are typically both common and precious in the form of metals, and it’s something that has been done to obtain beneficial resources for thousands of years. The mining industry is one where stainless steel has made it easier to take on larger projects and more profitable. It is used in a number of different applications to provide protection and efficiency, whether it is used in the actual mines themselves where employees and machines dig on the land, or in the bunk beds and mess halls where employees sleep.
