API 5L X46 Pipes are high-strength carbon steel line pipes manufactured in accordance with API Specification 5L, designed for the safe and efficient transportation of oil, gas, water, and other fluids in pipeline systems. The X46 grade indicates a minimum yield strength of 46,000 psi (317 MPa), offering higher strength compared to lower API 5L grades while maintaining good ductility and toughness.
Metal Tubular Products is a trusted stockist and global supplier of API 5L X46 Pipes, supplying a comprehensive range of sizes, wall thicknesses, and specifications to meet diverse project requirements. Pipes are available in both PSL 1 and PSL 2 supply conditions, allowing customers to select products based on required mechanical properties, testing levels, and quality controls.
API 5L X46 Pipes supplied by Metal Tubular Products are manufactured in various forms, including Seamless (SMLS), ERW, LSAW, and SSAW. This variety enables their use in small-diameter pipelines, long-distance transmission lines, and large-diameter onshore and offshore pipeline projects..
Known for their excellent strength-to-weight ratio, weldability, and resistance to internal pressure, API 5L X46 Pipes are widely used in oil and gas transmission, water pipelines, refinery piping, and energy infrastructure projects. PSL 2 pipes offer enhanced reliability through stricter chemical composition limits and mandatory impact testing..

API 5L X46 pipes are primarily used for the transportation of oil, gas, water, and other fluids in pipeline systems. They are widely applied in onshore and offshore projects, refineries, petrochemical plants, and water transmission lines due to their higher strength and good weldability.
The designation “X46” refers to the minimum yield strength of the pipe, which is 46,000 psi (317 MPa). Higher X numbers indicate higher yield strength and improved pressure-handling capability.
Yes, API 5L X46 pipes are available in both PSL 1 and PSL 2. PSL 2 includes stricter chemical composition limits, mandatory impact testing, and enhanced quality control compared to PSL 1.
API 5L X46 pipes are manufactured in various forms such as Seamless (SMLS), ERW, LSAW, and SSAW, allowing flexibility for different diameters, pressure ratings, and project requirements.
