Seamless Non-Alloy and Alloy Steel Tubes for Boilers and Pressure Vessels

DIN 17175 Steel Tubes are seamless non-alloy and alloy steel tubes designed for high-temperature applications, such as boiler installations, high-pressure pipelines, and pressure vessel construction. Conforming to the DIN 17175 standard, these tubes are suitable for temperatures up to 600°C, offering excellent corrosion resistance and high-temperature strength in industries like power generation, petrochemical, and chemical processing.

Manufactured through seamless hot-rolled or cold-drawn processes, DIN 17175 Steel Tubes undergo heat treatments like normalizing or annealing to enhance creep resistance and mechanical properties. Available in grades St35.8, St45.8, 15Mo3, 13CrMo44, and 10CrMo910, they range in outer diameters from 10 mm to 610 mm and wall thicknesses from 1 mm to 60 mm. Rigorous testing, including hydrostatic, ultrasonic, and non-destructive tests, ensures compliance with DIN 17175 standards. The alloyed compositions, with elements like molybdenum and chromium, enhance abrasion resistance, making them ideal for seamless alloy steel tubes.

These high-temperature piping solutions support welding methods like arc and gas fusion, with surface treatments such as galvanization or anti-corrosion coatings and end configurations like plain or beveled. Packaged in bundles or wooden crates, they ensure secure delivery. DIN 17175 tubes address challenges like thermal stress and corrosion, making them a reliable choice for boiler tubes and pressure vessel tubes.

DIN 17175 specifies seamless steel tubes made of carbon and alloy (heat-resistant) steels intended for elevated-temperature applications—up to about 600 °C—in boilers, heat exchangers, pipelines, and pressure vessels.

The standard includes non‑alloy grades (e.g., St 35.8, St 45.8) and alloy grades such as 15Mo3, 13CrMo44, 10CrMo910, and even 14MoV63.

- **St 35.8**: C ≤0.17%; Si 0.10–0.35%; Mn 0.40–0.80% - **St 45.8**: C ≤0.21%; Si 0.10–0.35%; Mn 0.40–1.20% - **15Mo3**: C 0.12–0.20%, Mo 0.25–0.35% - **13CrMo44**: C 0.10–0.18%, Cr 0.70–1.10%, Mo 0.45–0.65% - **10CrMo910**: C 0.08–0.15%, Cr 2.0–2.5%, Mo 0.9–1.2%

Typical ranges: - *St 35.8*: Tensile 360–480 MPa, Yield ≥235 MPa, Elongation ≥25% - *St 45.8*: Tensile 410–530 MPa, Yield ≥255 MPa, Elongation ≥21% - *15Mo3*: Tensile 450–600 MPa, Yield ≥270 MPa, Elongation ≥20–22% - *13CrMo44*: Tensile 440–590 MPa, Yield ≥290 MPa, Elongation ≥20–22% - *10CrMo910*: Tensile 450–600 MPa, Yield ≥280 MPa, Elongation ≥18–20%

OD ranges from ~14–711 mm; WT 2–60 mm; lengths typically single or double random (5–12 m), max ~14–18 m. Tolerances vary: OD ±0.6–0.9%, wall thickness ±9–17%.

Production via hot/cold rolling, pressing or drawing; steels are killed and cast; tubes are heat-treated over full length—normalizing, annealing, tempering, or quenching & tempering, depending on grade.

Required tests include tensile, ring flaring/flattening, impact/bending, hardness, non-destructive (e.g., hydrostatic), surface/dimensional inspection, and leakage testing.

Widely used in boilers, superheaters, heat exchangers, pipelines, pressure vessels, and heat-resistant equipment in power plants, petrochemical, and industrial sectors.

Marking includes standard, grade or material number, OD×WT, heat no., and manufacturer ID stamped near ends. Orders should specify standard, grade, dimensions, length, heat treatment, and inspection/test certificates required.

Commonly compared ASTM equivalents include: - St 35.8 ≈ ASTM A179 - St 45.8 ≈ ASTM A210 - 15Mo3 ≈ ASTM A335 P1 - 13CrMo44 ≈ ASTM A335 P12 - 10CrMo910 ≈ ASTM A335 P22
