Tricon Steel & Alloys is a Manufacturer, Supplier and Exporter of Duplex Steel S31803 Pipe in Mumbai, India. Our Duplex Steel S31803 Pipes is a high-performance solution in industrial piping, conforming to stringent standards set by the American Society for Testing and Materials (ASTM). These pipes belong to the duplex stainless steel family, characterized by their unique two-phase microstructure, comprising both austenitic and ferritic phases. This dual-phase structure imparts a rare combination of high strength and exceptional corrosion resistance, making Duplex Steel S31803 pipes indispensable for various demanding applications.

A notable attribute of ASTM A790 Duplex Steel, UNS S31803 pipes, is their superior corrosion resistance, which significantly exceeds standard austenitic stainless steels like the 304 and 316 grades. That makes them the material of choice for aggressive environments where corrosion is a critical concern, such as in marine environments, chemical processing industries, and oil and gas exploration and production. The exceptional performance of S31803 Duplex Steel Pipes in such corrosive settings is a testament to their robust composition and advanced metallurgical properties.

Duplex Steel UNS S31803 Seamless Pipes exhibit high mechanical strength, allowing them to withstand high-pressure and high-temperature conditions without experiencing deformation or failure. That makes them ideal for robust and durable piping systems, particularly in challenging applications like offshore oil platforms, desalination plants, and industrial processing facilities. Their ability to maintain structural integrity under extreme conditions makes them a preferred choice in industries that demand reliability and longevity.

Another key advantage of Duplex Steel S31803 Seamless Pipe is its excellent weldability. This property allows for easy fabrication and installation, which is particularly beneficial in constructing complex piping systems and structures. The ease of welding ASTM A790 Duplex Steel S31803 Pipes reduces project timelines and costs, contributing to more efficient and cost-effective engineering solutions.

These pipes also offer remarkable resistance to stress corrosion cracking (SCC) and pitting corrosion, enhancing their suitability for critical applications in harsh environments. The 2205 Duplex Stainless Steel Seamless Pipe, which includes UNS S31803 Pipes, is designed to provide long-term reliability and durability. That reduces maintenance requirements and an extended service life, ensuring systems remain operational with minimal downtime.

ASTM A790 UNS S31803 Pipes find extensive use across various industries due to their outstanding properties. In the oil and gas sector, they are commonly employed for transporting corrosive fluids such as sour gas and crude oil. The exceptional strength and corrosion resistance of the S31803 Pipe makes it ideal for these demanding applications. Additionally, they are widely used in chemical processing plants, where they easily handle corrosive chemicals and acids. The superior performance of Duplex Steel DIN 1.4462 Seamless Pipes in such environments highlights their importance in maintaining operational efficiency and safety.

Duplex Steel S31803 Pipe Manufacturing Process

The Rolling and Welding Stage

To begin our process, we first need to go through the rolling and welding stage. The stainless steel is placed through a checking process and cut at the edges in this stage.

Cleaning and Warming Stage

The rolled stainless steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand.

Cold-Drawing Stage

Sometimes, the required size isn’t obtained when the steel is brought through the mill directly. When using the cold-drawing process, the desired size is achieved when the pipes and tubing are coated with oxalic and soap solution and dragged over die plugs—the oxalic and soap solution help reduce friction when going through the cold cycle.

The Finishing Process

The final process is the finisher. Once the process of manufacturing stainless steel pipes and tubing is completed, you’ll now have to take them to a jet printer.
