Liam Steel, a top-notch manufacturer and supplier located in Manila, Philippines, specializes in high-quality Carbon Steel LSAW Pipes (Longitudinal Submerged Arc Welded). These pipes are crafted for high-pressure, large-diameter, and critical piping needs. Utilizing cutting-edge LSAW welding technology, they boast impressive dimensional accuracy, consistent wall thickness, and outstanding mechanical strength. Perfect for transporting oil, gas, water, and various industrial fluids, Liam Steel’s LSAW pipes guarantee leak-proof performance and a long lifespan. They’re widely trusted in the oil & gas, petrochemical, power generation, and water supply sectors for their durability, corrosion resistance, and reliability in tough industrial settings.
Carbon Steel LSAW Pipes are mainly made up of carbon (0.15–0.30%), manganese (0.60–1.20%), silicon (0.10–0.35%), phosphorus (≤0.05%), and sulfur (≤0.05%). This specific alloy mix gives them high tensile strength, toughness, and ductility. Typically, these pipes have a tensile strength ranging from 415–550 MPa and a yield strength of 250–350 MPa. The LSAW manufacturing process ensures consistent mechanical properties, smooth internal and external surfaces, and strong weld integrity. They also show excellent impact resistance, weldability, and corrosion resistance, making them perfect for high-pressure, long-distance fluid transport and large-scale industrial pipeline projects.
