API 5L Grade L290 Pipe, often called X42, is made up of carbon (up to 0.26%), manganese (up to 1.2%), phosphorus (max 0.03%), and sulfur (max 0.03%), along with some trace elements that enhance its properties. It boasts a minimum yield strength of 290 MPa (42,000 psi) and a tensile strength ranging from 415 to 490 MPa (60,200 to 71,000 psi). This pipe is well-regarded for its excellent weldability, resistance to corrosion, and durability under high pressure, making it ideal for various demanding pipeline applications in the oil, gas, and water transmission sectors, whether onshore or offshore.
API 5L Grade L290 Pipe is widely utilized for transporting oil, gas, and water in both high-pressure and high-temperature settings. You’ll often find it in natural gas and petroleum pipelines, offshore platforms, refineries, and petrochemical facilities. Thanks to its strong mechanical properties and resistance to corrosion, it’s perfect for sour service and critical infrastructure projects, including deep well drilling, water treatment systems, and structural foundations. L290 pipe is also used in construction, pile driving, and tunneling operations, where reliable performance and long-lasting durability are crucial under heavy loads and varying environmental conditions.
