Tricon Steel & Alloys is proud to offer a premium range of Stainless Steel 347/347H pipes, known for their exceptional corrosion resistance and high-temperature strength. These pipes are manufactured using top-quality raw materials, ensuring durability and reliability in various industrial applications.

Stainless Steel 347 is a stabilized austenitic stainless steel that contains niobium, which provides enhanced intergranular corrosion resistance. This alloy is ideal for applications where exposure to high temperatures is common, such as in the manufacturing of chemical processing equipment, heat exchangers, and boiler components. The addition of niobium also promotes the formation of chromium carbides, preventing sensitization during welding and ensuring the longevity of the material.

The 347H variant is the high-carbon version of 347, offering improved high-temperature strength. With its higher carbon content, Stainless Steel 347H pipes are well-suited for applications in elevated temperature environments, such as in thermal processing units, petrochemical plants, and refineries.

The pipes provided by Tricon Steel & Alloys undergo rigorous quality control measures to meet international standards. The seamless pipes exhibit excellent corrosion resistance, making them suitable for applications in aggressive chemical environments. Welded pipes, on the other hand, are available for applications that require cost-effective solutions without compromising performance.

Stainless Steel 347 / 347H Pipe

Both variants of Stainless Steel 347/347H pipes are highly versatile, providing exceptional performance in a wide range of temperatures and corrosive environments. Their resistance to crevice corrosion and stress corrosion cracking further enhances their suitability for challenging industrial settings.

Tricon Steel & Alloys understands the importance of precision and reliability in the manufacturing process. Their Stainless Steel 347/347H pipes boast smooth surface finishes and tight tolerances, ensuring easy installation and compatibility with various fittings and connectors. The company's commitment to quality makes it a trusted supplier for industries requiring high-performance stainless steel pipes.

347H Stainless Steel 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.
