About this part

Cold-drawn seamless carbon steel pressure tubes manufactured strictly to international boiler codes (ASTM A192 / ASME SA192 / DIN 17175 St35.8). Subjected to full-body ultrasonic flaw testing, hydrostatic pressure testing, and precision eddy-current inspection. Engineered for high heat transfer rates, superior ductility for expanding and bending, and high creep rupture strength under continuous thermal stress.

Key features

  • 100% seamless cold-drawn steel with smooth internal and external surface finish
  • High tensile and yield strength with optimal ductility for tube sheet expanding and welding
  • Strictly tested via hydrostatic pressure and non-destructive eddy current testing
  • Uniform wall thickness tolerance preventing premature hot spots and tube wall thinning
  • Available in standard lengths and custom cut-to-size specifications

Typical applications and wear

Fire tube boilers (smoke tubes), water tube boilers (risers/downcomers), superheaters, economizer bundles, and air preheaters. Wear stems from flue gas ash erosion, waterside oxygen pitting, and sulfur corrosion.

Compliance

Mill test certificates (such as EN 10204 3.1) and documentation can be supplied when specified; local retubing approval depends on the exact material, records, and jurisdiction.
