Carbon Steel API 5L 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 API 5L 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.
API 5L Grade B pipes comply with the API 5L standard, which governs the specifications for seamless and welded steel line pipes. In addition, IBR certification ensures that these pipes meet the stringent safety requirements for boilers, pressure vessels, and steam lines in India. This dual certification guarantees the pipes’ suitability for high-pressure and high-temperature service in industrial applications.
The chemical composition of Carbon Steel API 5L Gr.B IBR pipes typically includes Carbon (0.30% max), Manganese (1.20% max), Phosphorus (0.05% max), Sulfur (0.045% max), and Silicon (0.10% min). This carefully controlled alloy composition ensures optimal strength, ductility, and weldability. Low carbon content improves formability, while manganese and silicon enhance toughness and high-temperature performance.

Available in a wide range of sizes and thicknesses, Carbon Steel API 5L 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 API 5L 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.
API 5L Gr.B IBR pipes exhibit excellent mechanical performance, offering a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa. These pipes maintain dimensional stability and toughness under high-pressure and high-temperature conditions. Their excellent impact resistance ensures safety and reliability in oil, gas, and steam pipelines.
These pipes are manufactured using seamless hot-forming or electric resistance welded (ERW) techniques. Seamless pipes are made by hot extrusion and finishing, while welded pipes are produced by forming and joining steel coils or plates. The manufacturing process includes hydrostatic testing, nondestructive inspections, and heat treatment to ensure high-quality performance in IBR-certified applications.
