What is ASTM A312 TP316L?
ASTM A312 TP316L is a low-carbon austenitic stainless steel pipe with enhanced corrosion resistance due to the addition of molybdenum and chromium. The designation indicates its application for tubular products (TP), complying with the ASTM A312 standard for seamless, welded, and cold-worked austenitic stainless steel pipes, and represents the low-carbon (L) version of the 316 grade. This material is highly suitable for high-temperature, high-pressure, and corrosive environments, particularly those containing chlorides, such as in chemical processing and textile industries.
GNEE, as a supplier of ASTM A312 TP316L stainless steel pipes, provides these grades in both seamless and welded configurations, with specifications ranging from SCH 5 to SCH 160 and XXS. The pipes can be annealed for high-stress applications, offering excellent mechanical properties and strength, and are dual-certified. Commonly used in petroleum refining, food processing equipment, and the pulp and paper industry. At GNEE, you can purchase seamless steel pipes in any shape, including rectangular, hydraulic, square, and round. The lengths of ASTM A312 TP316L pipes are available as fixed length, single-random length, and double-random length, with ends available in threaded, beveled, and plain configurations. Additionally, we provide required test certifications and sell the products with comprehensive packaging options such as wooden crates and plastic caps.
