Seamless Cold-drawn Intermediate Alloy-steel Tubes For High-temperature Applications
Astm a199 tubes offer seamless alloy steel solutions for heat exchangers and condensers, ensuring high strength and corrosion resistance in high-temperature systems.
ASTM A199 Tubes are seamless, cold-drawn, intermediate alloy-steel tubes designed for heat exchangers, condensers, and similar heat transfer equipment, offering exceptional corrosion resistance and high-temperature strength. Conforming to ASTM A199/ASME SA199 standards, these tubes are ideal for heat exchanger tubes in petrochemical, oil refining, and power generation industries. Available in grades T5, T11, and T22, they provide superior durability in environments with temperatures ranging from -100°C to 625°C.
Manufactured through a seamless cold-drawn process, ASTM A199 Tubes undergo heat treatment (e.g., annealing or normalizing) to optimize mechanical properties and creep resistance. Available in outside diameters from 1/8” to 3” (3.2 mm to 76.2 mm) and wall thicknesses from 0.015” to 0.500” (0.4 mm to 12.7 mm), these tubes meet diverse project requirements. They are subjected to rigorous testing, including flattening, flaring, hardness, and hydrostatic or nondestructive electric tests, ensuring compliance with ASTM A199 standards. The chromium-molybdenum alloy composition enhances abrasion resistance, making them suitable for seamless alloy steel tubes in harsh conditions.
These seamless alloy steel tubes excel in high-temperature and corrosive environments due to their high tensile strength (e.g., min. 415 MPa for T5, 415 MPa for T11, 415 MPa for T22) and excellent corrosion resistance. Surface treatments like oil-dip, varnish, or shot blasting, and options for straight or U-bent configurations, support versatile installation in industrial piping systems. Packaged in wooden boxes or bundles with plastic paper, they ensure secure, sea-worthy delivery. ASTM A199 tubes are a reliable choice for engineers seeking durable condenser tubes for demanding applications.
Addressing challenges like thermal stress, corrosion, and high-pressure demands in heat transfer systems, ASTM A199 Tubes deliver exceptional performance, safety, and longevity. Their seamless design and alloyed composition make them ideal for critical applications in process industries.
