ASTM A335 P12 Pipes are high-temperature, high-pressure seamless alloy steel pipes manufactured in accordance with ASTM A335 / ASME SA335 standards. These pipes are chromium-molybdenum alloyed to provide excellent resistance to oxidation, corrosion, and creep at elevated temperatures. ASTM A335 P12 Pipes are widely used in critical industrial applications, including boilers, superheaters, reheaters, heat exchangers, and high-pressure piping systems in power plants, petrochemical plants, and refineries..
Metal Tubular Products is a worldwide stockist and supplier of ASTM A335 P12 Pipes, offering a comprehensive inventory of seamless pipes in various diameters, wall thicknesses, and lengths. Their global supply network ensures timely delivery to support both urgent maintenance needs and large-scale industrial projects. All pipes meet international standards and quality certifications for high-temperature service..
ASTM A335 P12 Pipes provide superior mechanical properties and long-term reliability under extreme conditions. Chromium content improves resistance to oxidation and corrosion, while molybdenum enhances creep strength, tensile properties, and high-temperature performance. These properties make P12 pipes suitable for critical piping systems operating at elevated temperatures and pressures.
The pipes supplied by Metal Tubular Products are manufactured using advanced seamless production methods and delivered in normalized and tempered condition to ensure uniform wall thickness, dimensional accuracy, and excellent surface finish. Their weldability and structural integrity after welding make them suitable for demanding industrial applications..

ASTM A335 P12 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 good strength and weldability.
The designation “X42” refers to the minimum yield strength of the pipe, which is 42,000 psi (290 MPa). Higher X numbers indicate higher yield strength.
Yes, ASTM A335 P12 Pipes are available in both PSL 1 and PSL 2. PSL 2 has stricter chemical composition limits, mandatory impact testing, and enhanced quality control compared to PSL 1.
ASTM A335 P12 Pipes are manufactured in various forms such as Seamless (SMLS), ERW, LSAW, and SSAW, allowing flexibility for different pressure, diameter, and project requirements.
ASTM A335 P12 Pipes are stocked and supplied worldwide by Metal Tubular Products, offering a wide size range, quick delivery, and compliance with international quality standards for global pipeline projects.
