The key features of Stainless Steel 321 Pipes & Tubes include:

  • Corrosion Resistance: Stainless Steel 321 demonstrates outstanding resistance to a wide range of corrosive media, including acids and alkaline solutions.
  • High-Temperature Strength: These pipes and tubes maintain their mechanical properties at elevated temperatures, making them suitable for applications involving heat and thermal processing.
  • Weldability: Stainless Steel 321 is easily weldable, and the pipes and tubes can be seamlessly integrated into complex structures without compromising their integrity.
  • Versatility: These components find applications in diverse industries such as chemical processing, oil and gas, and power generation.

Stainless Steel 321H, an alloy variant of 321, contains higher carbon content, enhancing its high-temperature strength. The SS 321H Pipes are specifically designed to operate in environments with elevated temperatures, making them ideal for applications such as heat exchangers and furnace parts.

Key attributes of Stainless Steel 321H Pipes & Tubes include:

  • Elevated Carbon Content: The increased carbon content in Stainless Steel 321H enhances its ability to withstand high temperatures, making it suitable for demanding applications.
  • Creep Resistance: These pipes and tubes exhibit excellent resistance to creep, ensuring long-term performance in high-temperature conditions.
  • Heat Treatment: Stainless Steel 321H Tubes can be subjected to heat treatment processes, further improving their mechanical properties and ensuring optimal performance in challenging environments.
  • Chemical Stability: Similar to SS 321, SS 321H offers superior chemical stability, making it resistant to various corrosive substances.

Stainless Steel 321 Pipe and Tube Manufacturing Process

Rolling and Welding

Rolling and Welding The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process.

Pipe and Tube Cutting

Length Cutting Rolled pipes and tubes thus manufactured are cut to the required lengths depending upon the industrial demand. We use a variety of methods—sawing, lathe cutting, rotary cutting, supported shear cutting, dual-blade shear cutting, and laser cutting.

Cleaning and Heating Phase

Cleaning and Heating Phase Subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace.

Cold Drawing Process

Cold Drawing Process Required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

Finishing Process

Finishing Process Pipe and tubes are then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine then mark the finished pipes or tubes. Then they marked with grade of material, size, heat number.

Third Party Inspection

Third Party Inspection Finish pipes & tubes then stamp with third party inspection before passing on to exporters. The tubes or pipes thus produced will undergo certain testing and quality checks.
