Bulan Pipes and Tubes stands out as a top-notch manufacturer and supplier located in Jakarta, Indonesia. They specialize in Stainless Steel 347 and 347H Heat Exchanger Tubing, designed to excel in high-temperature and corrosive settings. These tubes are crafted to meet ASTM A213 and ASTM A249 standards, featuring stabilized austenitic stainless steels that include niobium (columbium) to ward off carbide precipitation and intergranular corrosion during thermal cycling and welding. The Grade 347H, with its higher carbon content, provides enhanced creep strength at elevated temperatures. With a variety of sizes, thicknesses, and surface finishes available, these tubes are a reliable choice for critical heat transfer applications in refineries, power plants, and petrochemical facilities.
Stainless Steel 347/347H Heat Exchanger Tubing is composed of approximately 17–20% chromium, 9–13% nickel, and niobium (at least 10 times the carbon content) for stabilization. The 347H variant has a higher carbon content (around 0.04–0.10%) to boost creep and stress rupture strength at temperatures exceeding 537 °C (1000 °F). Typical tensile strength falls between 515–750 MPa, with yield strength hovering around 205 MPa. These alloys are known for their excellent oxidation resistance, good ductility, and dependable mechanical properties during extended high-temperature use. Their stabilized composition helps prevent sensitization and intergranular attack, ensuring safe and consistent performance in corrosive and thermal cycling conditions.
