Inox Steel India is a leading manufacturer and exporter of EN 10216-2 Seamless Carbon Steel Pipes in grades P235GH and P265GH, widely used in industrial boilers, pressure vessels, heat exchangers, economizers, refinery piping, superheated steam lines, and thermal power plants.
EN 10216-2 is the European standard for non-alloy pressure steel pipes, designed specifically for high-temperature and high-pressure applications in thermal, chemical, and petrochemical industries. These grades are known for excellent creep resistance, pressure resistance, high-temperature stability, weldability, and dimensional accuracy.
Our seamless boiler tubes are manufactured through hot-finishing (HFS), cold-finishing (CDS), normalizing heat treatment, hardness control, hydro testing, and 100% NDT, ensuring compliance with international boiler safety standards.
P235GH is the standard pressure steel grade, whereas P265GH is the higher-strength boiler quality steel suitable for more demanding steam and pressure applications.
EN 10216-2 covers seamless steel tubes for pressure purposes, intended for use at elevated temperatures. These pipes are designed to withstand:
These pipes are mainly used for:
The GH suffix means “GeHärtet” in German — indicating suitability for high-temperature pressure service.
Pipes are supplied in normalized (+N) condition to handle high-pressure and high-temperature duty cycles safely.
