API 5L Plate / Sheet / Coil
API 5L Plate, Sheet, and Coil are high-strength carbon steel products manufactured These products are designed for use in the fabrication of oil, gas, water, and petrochemical pipelines, pressure vessels, and structural components requiring excellent strength and toughness.API 5L plates and sheets are widely used in the manufacturing of line pipes, pipe fittings, flanges, outlet fittings, and welded structures for onshore and offshore applications. API 5L coils are commonly used for pipe forming, large-diameter welded pipes, and custom fabrication where uniform mechanical properties and dimensional accuracy are critical.
API 5L plates, sheets, and coils are supplied in PSL1 and PSL2 specifications to meet different service conditions. PSL2 material offers enhanced chemical composition control, improved impact resistance, and stricter mechanical property requirements for demanding pipeline environments.
Commonly supplied grades include API 5L , API 5L X42, API 5L X52, API 5L X56, API 5L X60, API 5L X65, API 5L X70, and API 5L X80. Lower grades are suitable for moderate pressure applications, while higher grades are preferred for long-distance, high-pressure, and high-capacity pipeline projects.
API 5L X65, X70, and X80 plates and coils are extensively used in critical pipeline systems due to their superior yield strength, tensile strength, and resistance to deformation under extreme operating conditions.
Revinox is a reliable supplier of API 5L plates, sheets, and coils in both PSL1 and PSL2 conditions. These materials are available in as-rolled, normalized, TMCP, and customized thickness ranges to meet project-specific fabrication and performance requirements for global oil, gas, and energy infrastructure projects.
