Liam Steel, a top-notch manufacturer and supplier located in Manila, Philippines, specializes in high-quality Carbon Steel JIS G3445 Pipes. These pipes are designed for strength, reliability, and a long lifespan in industrial piping systems. Crafted in line with the Japanese Industrial Standard (JIS G3445), they boast impressive dimensional accuracy, a smooth surface finish, and outstanding mechanical performance. Commonly found in the oil & gas, petrochemical, power generation, and water supply sectors, JIS G3445 pipes are perfect for both medium- and high-pressure applications. With rigorous quality control and precision manufacturing, Liam Steel ensures these pipes are well-suited for critical fluid transport in demanding industrial settings.
Carbon Steel JIS G3445 Pipes are mainly made up of carbon (0.15–0.30%), manganese (0.30–0.90%), phosphorus (≤0.05%), sulfur (≤0.05%), and silicon (0.10–0.35%). This blend strikes a great balance between tensile strength, ductility, and toughness. Typically, these pipes deliver a tensile strength of 410–550 MPa and a yield strength of 250–350 MPa. Their excellent weldability, impact resistance, and dimensional stability make them suitable for both seamless and welded constructions. JIS G3445 pipes are perfect for transporting fluids under high or medium pressure while ensuring mechanical integrity and long-lasting reliability.
