ASTM A199 / SA199 seamless cold-drawn alloy steel tubes, OD 1/8–3", WT ≥0.015", ideal for boilers, heat exchangers, condensers & superheater
ASTM A199 / SA199 covers seamless alloy steel tubes engineered for high-temperature and high-pressure applications where strength, oxidation resistance, and creep resistance are essential. Manufactured per the specifications of ASTM International and ASME, A199 tubes are widely used in boilers, heat exchangers, superheaters, and high-temperature processing equipment.
These tubes are produced through seamless forging and finishing to ensure uniform wall thickness, high mechanical performance, and structural integrity under extreme conditions. Various alloy grades under A199 improve service life and reliability in critical industrial applications.
