We specialize in Grade A, Grade B, and Grade C seamless carbon steel pipes manufactured as per ASTM A106 / ASME SA106, suitable for high-temperature and high-pressure applications in refineries, boilers, power plants, and petrochemical industries. Our seamless pipes are produced using high-grade carbon steel billets, hot-finished or cold-drawn processes, and undergo rigorous testing to ensure structural integrity and performance in harsh operating conditions.
Each pipe manufactured at Inox Steel India undergoes hydro testing, ultrasonic testing, eddy current testing, bend testing, and visual-dimension inspection, ensuring full compliance with ASTM, ASME, IBR, and international standards.
Our A106 Grade A/B/C pipes are widely used in steam lines, boiler tubes, refinery piping, heat exchangers, petrochemical service, fluid conveyance, and high-temperature systems where uninterrupted flow and pressure integrity are critical.
ASTM A106 seamless pipe is a Carbon Steel High-Temperature Seamless Pipe designed for:
It is commonly used in pipelines that operate at temperatures above 425°C and under constant pressure.
This rigorous production ensures that every ASTM A106 pipe from Inox Steel India is fit for extreme temperature and pressure conditions.
