GNEE manufactures and supplies API 5L B Welded Pipes. With years of experience, GNEE produces high diameter pipes for multiple industries.
Iron is the main material of API 5L B Carbon Steel Pipes followed by alloying elements like 0.30% Carbon, 1.20% Manganese, 0.40% Copper, 0.40% Nickel, 0.40% Chromium, 0.15% Molybdenum. Trace amounts of Phosphorus, Sulfur and Vanadium. The main advantage of API 5L B Grade Straight Seam Carbon Pipes is high crack resistance and can resist sulfide stress cracking due to hydrogen sulfide deposition which allows it to be used in sour services.
API 5L GR.B LSAW Steel Pipes are used in petrochemical industry, open as well as underground and underwater environments and oil and gas. They range in diameter from 1/2 inch to 48 inches.
