Import Astm A199 Heat-Exchanger Tubes — Buy in Bulk from Supplier in China

Astm a199 heat-exchanger tubes from Sunny Steel Tubosacero Ltd. are seamless cold-drawn intermediate alloy-steel tubes engineered for thermal applications. They conform to ASTM A199/A199M-92, a specification that defines the chemical and mechanical requirements for carbon and alloy steel tubes used in heat exchangers, condensers, and similar equipment. The tubes are designed to handle high-pressure and high-temperature environments, ensuring reliable performance in critical systems where heat transfer efficiency is paramount.

These tubes are manufactured with precise dimensional control, offering a range of sizes and wall thicknesses to meet specific engineering needs. The seamless construction eliminates weld lines, reducing the risk of failure under stress and improving resistance to corrosion and fatigue. Typical industry standards for such tubes include tensile strengths exceeding 415 MPa and yield strengths above 205 MPa, with elongation often around 30%. The alloy composition, usually including chromium and molybdenum, enhances resistance to oxidation and scaling at elevated temperatures.

Industries such as oil and gas, power generation, and chemical processing rely on these tubes for boiler systems, refrigeration units, and other heat-exchange applications. Buyers sourcing from Sunny Steel Tubosacero Ltd. in China can expect products tailored to international standards, with packaging and logistics arranged for bulk shipment. The supplier’s address in Hebei, Shanghai, positions it well for export, though buyers should confirm lead times and incoterms directly with the supplier.
