Stainless Steel Pipe Production: Technical Processes and Industrial Applications
Stainless steel pipes are indispensable for sectors such as chemistry, food, energy and construction due to their corrosion resistance, high durability and hygienic properties. So how are these pipes produced? What technologies and standards are used? Here are all the details:

Stainless Steel Pipe Types

1. Welded Pipes:

• Also known as welded pipes.
• Area of Use: Low pressure systems, decorative applications.

1. Seamless Pipes:

• It is produced in one piece.
• Area of Use: High pressure, temperature and critical industrial systems.

Stainless Steel Pipe Manufacturing Methods

A. Welded Pipe Production

1. Strip Preparation:

• Stainless steel strips (coils) such as 304, 316L are used.

1. Strip Forming:

• The strip is formed into a cylindrical form.

1. Welding Process:

• TIG Welding: Welding is done under argon gas for high quality seams.
• Laser Source: It is a sensitive and fast method.

1. Stitch Correction:

• The weld area is ground and made smooth.

1. Sizing and Calibration:

• The pipe is drawn to the desired diameter and thickness.

B. Seamless Pipe Production

1. Preparation:

• Stainless steel billets are heated to 1200-1300°C.

1. Drilling:

• A hole is drilled in the center of the log (using a mandrel).

1. Hot Rolling:

• The perforated billet is lengthened on rolling mills and given a pipe form.

1. Cold Drawing:

• Cold drawing method is used for pipes that require high precision.

1. Heat Treatment:

• Internal stresses are eliminated and corrosion resistance is increased by annealing.

Stainless Steel Grades Used

Quality Control and Certification

• Pressure Test: Pipes are subjected to a hydrostatic test to withstand pressures of 500-3000 bar.
• Ultrasonic Testing: Cracks in the welding line are detected in welded pipes.
• Chemical Analysis: Cr, Ni, Mo ratios of the material are checked.
• Certificates: TSE EN 10217-7, ASTM A312, API 5LC.

Stainless Steel Pipe Production in Türkiye

• Local Manufacturers: Erdemir, Tosçelik and private steel factories.
• Export: Annual export of 50,000+ tons to Europe, Middle East and Africa.
• Technology: Investments made in laser welding and automation systems in the last 5 years.

Advantages of Stainless Steel Pipes

✅ Longevity: 50+ years of corrosion-free use.
✅ Hygienic: Bacteria-proof surface in the food and pharmaceutical industry.
✅ Energy efficiency: Minimizes flow loss with smooth inner surface.
✅ Recycle: 0 is recyclable.

Sectoral Use Cases

• Chemical Industry: Acid and base transportation lines.
• Energy: Natural gas pipelines and hydrogen storage systems.
• Construction: Indoor water installations and fire sprinkler systems.
• Food: Milk processing lines and fermentation tanks.

Frequently Asked Questions (FAQ)

Q: Why are stainless steel pipes expensive?
A: Alloying elements such as nickel and chromium and energy-intensive production processes increase costs.

Q: How to choose between welded and seamless pipe?
A: Decide based on pressure and temperature requirements. Seamless pipes are ideal for high pressure.

Q: How to clean stainless steel pipes?
A: Clean with pH neutral detergent and soft cloth. Avoid abrasive chemicals.
