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.

Incoloy 800 Pipes: Incoloy 800 is a basic grade with a composition of nickel, chromium, and iron. It exhibits excellent resistance to oxidation, carburization, and sulfidation. Incoloy 800 Pipe maintains its stability and mechanical properties at high temperatures, making it suitable for applications in heat-treating equipment and chemical processing.
Incoloy 800H Pipes: Incoloy 800H is a modified version with higher carbon content for enhanced creep resistance. The higher carbon content minimizes the risk of sensitization during prolonged exposure to elevated temperatures. Incoloy 800H Pipe is commonly used in industrial furnaces, petrochemical plants, and power generation facilities.
Incoloy 800HT Pipes: Incoloy 800HT offers further improvements in creep and rupture strength compared to Incoloy 800H. It is designed for applications where extended service at temperatures above 1000°F (538°C) is required. Applications include nitric acid processing, heat exchangers, and industrial gas turbines.
