ASTM A199 لوله های مبادله گرما لوله های تهویه کننده لوله های فولادی آلیاژ سرد

ASTM A199 / A199M is a standard specification for seamless cold-drawn intermediate alloy-steel tubes used in heat exchangers, condensers, and similar heat transfer apparatus. These tubes are manufactured from chromium-molybdenum and chromium-molybdenum-silicon alloy steels, offering excellent resistance to high temperatures and pressures. ASTM A199 Heat-exchanger Tube is designed for service temperatures ranging from –100°C to +625°C (-150°F to 1150°F). They are widely used
