Duplex Stainless Steel Seamless Pipe related introduction
Duplex Stainless Steel Seamless Pipe is one of the most sought-after forms of stainless steel pipe, constructed using austenitic and ferritic stainless steels combined for corrosion resistance and strength properties. Specifically tailored for use in applications where chlorides or sulfides present such as in the oil and gas industry or highly corrosive environments exist such as chlorides and sulfides, this pipe can provide superior resistance. It's commonly found used for this application due to these qualities.
2205 duplex stainless steel is one of the most frequently used grades of duplex stainless steel, featuring 22% chromium and 5% nickel in its composition. This grade can be found across industries, such as chemical processing, desalination, and water management as well as transportation design & construction sectors. Due to its high yield strength, it allows it to be used in thinner sections which saves money in terms of materials cost. Furthermore, it has a higher resistance to stress corrosion cracking than other grades so can withstand higher pressure environments more readily than other grades of stainless steel, allowing it to be applied more broadly across applications that require stress.
Duplex pipes are commonly utilized in the offshore oil and gas industry for transporting corrosive liquids. Due to their ability to withstand severely corrosive environments such as those containing sulfides, chlorides, and nitric acid, duplex pipes make an ideal choice for use on platforms, pipelines, storage vessels as well as refineries and chemical plants.
Duplex stainless steel pipe is an attractive material choice for use in various industries due to its strength. In particular, it excels when mixing salts and acids that could corrode austenitic stainless steel. Furthermore, duplex pipes can withstand the corrosion caused by flue gas emissions that contain harmful toxins which must be cleaned out before being released back into the atmosphere.
Duplex steel stands out as being particularly strong and resistant to corrosion among stainless steel grades due to its unique composition: ferritic phase provides strength while austenitic lattice provides ductility and stress corrosion cracking resistance. Because of this dual nature, duplex steel makes an attractive choice in many environments due to its strength, weldability, and low weight - two advantages that combine perfectly for long-term applications.
