Dang Steel Manufacturer and Suppliers, located in Da Nang, Vietnam, has built a solid reputation as a reliable producer and exporter of top-notch heat exchanger and condenser tubing, including Carbon Steel ASME SA 179 Tubing. Renowned for their precision engineering and strict adherence to ASME standards, Dang Steel provides tubing solutions for various industries, such as power generation, petrochemicals, refrigeration, and HVAC. With cutting-edge manufacturing techniques and rigorous quality control, their SA 179 tubes deliver outstanding thermal conductivity, corrosion resistance, and precise dimensions. Dang Steel is dedicated to offering high-performance tubing products that meet international standards, ensuring long-lasting reliability and efficiency in demanding heat transfer systems.
ASME SA 179 Tubing is crafted from low-carbon steel, typically containing 0.06–0.18% carbon and 0.27–0.63% manganese, with very low levels of phosphorus and sulfur. This specific composition guarantees excellent ductility, weldability, and thermal conductivity. The tubing boasts a minimum tensile strength of 325 MPa and a yield strength of 180 MPa, along with a minimum elongation of 35%. It is manufactured in a cold-drawn, seamless form, which results in a superior surface finish, tight dimensional tolerances, and smooth internal surfaces. SA 179 tubing is specifically engineered for heat exchanger and condenser applications that operate under low to moderate pressure and temperature.
