Boiler Tubes – ASTM A210 / A213 / DIN 17175 Manufacturer in India

High-Temperature · High-Pressure · Seamless Boiler & Superheater Tubes Inox Steel India

Inox Steel India is a leading manufacturer, stockist, and global exporter of Seamless Boiler Tubes conforming to ASTM A210, ASTM A213, and DIN 17175 standards. These tubes are engineered for high-temperature and high-pressure service in boilers, superheaters, reheaters, economizers, heat exchangers, and thermal power generation units.

Our boiler tubes operate reliably under the harshest operating conditions involving:

  • Superheated steam (up to 650°C)
  • Pressure up to 200+ bar
  • Thermal shock & cyclic temperature variations
  • Oxidation, sulphur-bearing flue gases, and corrosive environments
  • High creep, stress rupture, and long service life expectations

With precision manufacturing, strict heat-treatment control, advanced NDT testing, and full certification, Inox Steel India supplies boiler tubes for power plants, refineries, petrochemical units, sugar factories, industrial boilers, HRSG units, and process heating systems across India, GCC, Africa, Europe, USA, South Asia, and South America.

Understanding Boiler Tubes – Why These Standards Matter

Boiler tubes must withstand extreme mechanical and thermal conditions. The materials and standards ensure:

  • High Pressure Strength – The tubes sustain continuous steam pressure, resisting deformation and creep.
  • High Temperature Stability – Mechanical properties remain stable even at 450°C – 650°C.
  • Resistance to Oxidation & Flue Gases – DIN and ASTM alloys handle sulphur oxides, nitrogen oxides, and burnt fuel gases.
  • Dimensional Accuracy – Precise OD/WT ensures proper fitment in tube sheets and headers.
  • Reliability in Continuous Operation – Plants depend on zero failure; tube bursts or leakages cause massive downtime.

Because of these critical needs, industries rely only on globally proven standards like A210, A213 & DIN 17175.

Overview of Boiler Tube Standards

🔹 ASTM A210 – Medium Carbon Steel Boiler TubesUsed for:

  • Fire-tube boilers
  • Economizer tubes
  • Low-to-medium temperature heating systems

Key properties:

  • Good pressure resistance
  • Suitable for high wall thickness
  • Cost-effective for carbon steel boilers

🔹 ASTM A213 – Alloy & Stainless Steel Boiler TubesUsed for:

  • Superheaters
  • Reheaters
  • High-temperature steam lines
  • Chemical and petrochemical heat exchangers

Popular grades:

  • T11, T22 → Ferritic alloy steel (elevated temperature strength)
  • TP304, TP316, TP321 → Austenitic stainless steels

🔹 DIN 17175 – German Standard High-Temperature TubesGlobal favourite for power plant boilers.

Common grades:

  • St35.8 / St45.8 — Standard grade boiler tubes
  • 15Mo3 — Excellent resistance to sulphurous flue gases
  • 13CrMo4-5 / 10CrMo9-10 — High creep strength, ideal for superheaters

How High-Temperature Boiler Tubes Are Manufactured

Inox Steel India uses advanced facilities to produce boiler tubes capable of continuous high-pressure and high-temperature service.

Manufacturing Steps:

  1. Hot Piercing & Hollow Tube Formation: Billets are heated to ~1200°C and pierced to form seamless hollows.
  2. Cold Drawing / Hot Finishing: Depending on grade & requirement: Cold-drawn → tighter tolerances; Hot-finished → thicker walls, heavy-duty strength.
  3. Heat Treatment: Critical for boiler performance: Normalizing, Annealing, Quenching & tempering, Stress-relieving. Each heat treatment cycle is recorded and supplied in the MTC.
  4. Surface Finishing: Pickled, Black surface, Polished (SS grades).
  5. NDT Testing: Mandatory for boiler safety: Eddy current test, Ultrasonic test, Hydrostatic pressure test, Magnetic particle inspection.
  6. Final Processing: Bevelled ends, Deburring, Anti-corrosion oil coating.

Key Advantages of Boiler Tubes from Inox Steel India

  • High strength at elevated temperatures: Boiler tubes maintain structural integrity under continuous steam exposure.
  • Excellent pressure resistance: Engineered for uniform wall thickness & high mechanical strength.
  • Outstanding thermal fatigue performance: Crucial for systems with constant start-stop heat cycles.
  • Superior oxidation and corrosion resistance: Especially in alloy steel & DIN 17175 moly-chrome grades.
  • Long service life & reduced maintenance: Reduces plant downtime and operational cost.
  • International acceptance: Used in EPC projects, Power plant installations, Refinery boiler upgrades, and Overseas turnkey projects.
