At Esha Steel, we proudly supply premium API 5L Grade L320 Pipes to industries across Kolkata and nationwide. Manufactured according to API 5L standards, these pipes are designed for medium-pressure applications in oil, gas, and water pipeline systems. Esha Steel ensures precise dimensions, strict quality control, and superior mechanical performance. Trusted by petrochemical, energy, and industrial sectors, L320 pipes offer excellent weldability, strength, and corrosion resistance, making them ideal for safe, durable, and efficient operation in medium-pressure pipeline networks and industrial fluid transport systems.
API 5L Grade L320 Pipes are made from carbon-manganese steel with carefully controlled carbon, manganese, phosphorus, sulfur, and silicon content. This composition provides high strength, ductility, and toughness suitable for medium-pressure pipeline systems. Mechanically, L320 pipes provide a minimum yield strength of 320 MPa and tensile strength of 420–550 MPa, along with good elongation and impact resistance. Their uniform microstructure ensures excellent weldability, dimensional stability, and ease of fabrication. These properties make L320 pipes suitable for oil, gas, and water transport applications that require reliable performance, durability, and long-term service life.
