Carbon Steel A106 Gr.B IBR Pipes and Tubes are manufactured to meet stringent industrial standards and IBR (Indian Boiler Regulations) requirements. These pipes are designed for high-temperature and high-pressure applications, making them suitable for boilers, refineries, and power plants.
The seamless construction of A106 Gr.B IBR pipes ensures excellent mechanical strength, uniformity, and durability. These pipes are capable of withstanding extreme operating conditions without deformation or failure, ensuring reliable performance over long service life.
ASTM A106 Grade B IBR pipes conform to the international standard ASTM A106 and meet all requirements specified by the Indian Boiler Regulations, ensuring their suitability for boiler and pressure vessel applications in India. The IBR certification guarantees that the pipes have been inspected and approved for use in steam-generating systems, maintaining safety and reliability under critical conditions.
The chemical composition of Carbon Steel A106 Gr. B pipes includes Carbon (0.30% max), Manganese (1.20% max), Phosphorus (0.035% max), Sulfur (0.035% max), and Silicon (0.10% min). This well-balanced alloy composition ensures optimum mechanical strength, hardness, and heat resistance, making it ideal for high-pressure service and seamless piping systems that transport steam, oil, gas, and other fluids.

Available in a wide range of sizes and thicknesses, Carbon Steel A106 Gr.B IBR Pipes offer flexibility for various industrial applications. They are ideal for transporting steam, water, gas, and oil, providing safety and efficiency in high-pressure systems.
The chemical composition of A106 Gr.B IBR Pipes includes carbon, manganese, phosphorus, sulfur, and silicon, carefully balanced to enhance strength and corrosion resistance. This ensures that the pipes maintain their integrity under demanding operational conditions while meeting industry standards.
A106 Grade B IBR pipes exhibit outstanding mechanical properties, offering a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa. These pipes maintain excellent performance even under high temperature and pressure, providing superior ductility and impact resistance. Their mechanical stability makes them a preferred choice for thermal power plants, refineries, and steam pipelines.
The pipes are manufactured using the seamless hot finishing process, followed by cold drawing when required to achieve precise dimensions and surface finish. After forming, each pipe undergoes normalizing or heat treatment to enhance its mechanical strength and grain structure. IBR inspectors verify every stage of production, ensuring compliance with Indian Boiler Regulation standards before approval.
