Stainless Steel 347 and 347H are chromium-nickel austenitic stainless steel alloys renowned for their exceptional corrosion resistance, high temperature strength, and superior mechanical properties. These alloys are widely used in various industrial applications, and their seamless pipes and tubes play a crucial role in ensuring the integrity of critical processes.

Stainless Steel 347 Pipes & Tubes:
The Stainless Steel 347 pipes and tubes are engineered with precision to meet the demanding requirements of industries such as petrochemical, chemical, and aerospace. These seamless pipes exhibit excellent corrosion resistance against intergranular corrosion and sensitization, making them ideal for applications in high-temperature environments.

The key features of Stainless Steel 347 pipes include:

  • Corrosion Resistance: The alloy's resistance to corrosion, especially in environments with high temperatures and harsh chemicals, makes it a preferred choice for various industrial applications.
  • High Temperature Strength: Stainless Steel 347 pipes maintain their strength and structural integrity even at elevated temperatures, making them suitable for applications involving heat and thermal cycling.
  • Weldability: These pipes are easily weldable, allowing for convenient fabrication and installation processes, reducing downtime in industrial operations.

Stainless Steel 347H Pipes & Tubes:
Stainless Steel 347H is the high-carbon version of the 347 alloy, offering enhanced high-temperature strength and improved creep resistance. The seamless pipes and tubes made from Stainless Steel 347H are designed to withstand extreme conditions and provide superior performance in critical applications.

Key attributes of Stainless Steel 347H pipes include:

  • Elevated Temperature Performance: With a higher carbon content, Stainless Steel 347H pipes excel in applications where prolonged exposure to high temperatures is a concern, maintaining mechanical properties under challenging conditions.
  • Creep Resistance: The alloy's resistance to creep deformation at high temperatures makes it suitable for applications requiring prolonged exposure to elevated temperatures.
  • Versatility: Stainless Steel 347H pipes and tubes find applications in various industries, including power generation, chemical processing, and heat exchangers.

Stainless Steel 347 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.
