Handa Carbon Steel Seamless Pipe – 1/8” to 32” OD, Precision Hot/Cold Finished

Handa Carbon Steel Seamless Pipes are produced from solid round steel billets that are expertly heated and pierced to form a hollow tube, followed by hot-rolling, cold-rolling, or cold-drawing to achieve the desired dimensions and mechanical properties. Manufactured in accordance with stringent quality standards, these seamless pipes deliver superior strength, uniformity, and reliability, making them ideal for high-pressure and high-temperature applications.

The production process ensures tight tolerances and consistent wall thickness. Each pipe undergoes advanced dimensional sizing via high-speed rotary cone drills and is cooled, straightened, and thoroughly tested for surface and internal defects. These pipes are crafted from carbon steel—an iron-carbon alloy whose properties such as strength, ductility, and hardness vary depending on carbon content.

Seamless carbon steel pipes are indispensable in critical systems across the oil & gas, petrochemical, power generation, construction, and mechanical manufacturing sectors.
