High-temperature Pressure Applications
En 10216-2 p265gh seamless carbon steel tube offers high strength and corrosion resistance for high-temperature pressure applications in boilers, heat exchangers, and power plants.
EN 10216-2 P265GH Seamless Carbon Steel Tube is a high-quality non-alloy steel tube designed for high-temperature and pressure applications, offering excellent corrosion resistance and mechanical strength. Conforming to the EN 10216-2 standard, this seamless steel tube is ideal for boiler tubes, heat exchangers, and pressure vessels in industries such as power generation, oil and gas, and petrochemicals. With a steel number of 1.0425, the P265GH grade features a balanced composition with up to 0.20% carbon and 0.80-1.40% manganese, ensuring reliable performance in elevated temperature environments up to 450°C.
Manufactured through seamless processes, EN 10216-2 P265GH Seamless Carbon Steel Tubes are hot-rolled or cold-finished, followed by heat treatments such as normalizing to optimize their microstructure for strength and toughness. Available in outer diameters from 10.2mm to 711mm and wall thicknesses from 1.6mm to 100mm, with lengths of 5.8m, 6m, 11.8m, or random (5-12m), they meet diverse project requirements. Surface treatments like varnishing, black paint, or 3LPE coatings enhance corrosion resistance, while plain, beveled, or threaded ends ensure compatibility with industrial piping systems.
The Seamless Steel Tube undergoes rigorous testing, including chemical analysis, tensile tests at elevated temperatures, impact tests, and leak-tightness tests (hydrostatic or electromagnetic), to ensure compliance with EN 10216-2 standards for test categories TC1 and TC2. With a tensile strength of 410-570 MPa, a minimum yield strength of 265 MPa, and an elongation of at least 23%, these tubes provide reliable performance under high-pressure and high-temperature conditions. Their robust properties make them suitable for transporting hot liquids and gases in boiler tubes and steam pipelines.
Compatible with fittings and flanges conforming to standards like EN 10253-2 or ASTM A234, EN 10216-2 P265GH Seamless Carbon Steel Tubes integrate seamlessly into complex industrial piping networks. Their ASTM equivalent, ASTM A106 Grade B, shares similar mechanical properties but may differ slightly in chemical composition. These tubes are widely used in power plants, chemical processing, and refineries, where their weldability and durability ensure safety and efficiency.
Engineered to withstand thermal stress and corrosion in high-temperature environments, EN 10216-2 P265GH Seamless Carbon Steel Tubes provide a cost-effective, durable solution for engineers seeking reliable boiler tubes and high-temperature piping. Their seamless construction ensures enhanced pressure-bearing capacity, making them ideal for critical applications in power generation and industrial processes.

Non-alloy steel tubes are manufactured from steel primarily composed of iron and carbon, with little or no significant alloying elements. These tubes are widely used for general-purpose structural and mechanical applications.
The absence of expensive alloying elements makes these steel tubes highly economical, ideal for basic mechanical strength and forming applications.
Low carbon content ensures excellent weldability with minimal preheating, suitable for standard fabrication and construction needs.
