Bulan Pipes and Tubes is a reputable manufacturer and supplier located in Jakarta, Indonesia, focusing on top-notch Super Duplex Steel Seamless Pipes. These pipes are designed to deliver exceptional strength and impressive corrosion resistance, even in the toughest environments. They’re crafted according to ASTM A790 and other international standards, available in grades like UNS S32750 and UNS S32760, which provide excellent resistance to pitting, crevice, and stress corrosion cracking. With a variety of diameters, wall thicknesses, and lengths, these pipes cater to the needs of offshore, chemical processing, desalination, and power generation industries. Customers trust Bulan Pipes and Tubes for their consistent quality and reliable service.
Super Duplex Steel Seamless Pipes generally consist of about 24–26% chromium, 6–8% nickel, and 3–5% molybdenum, along with a bit of nitrogen (around 0.2–0.3%) to boost strength and corrosion resistance. Their unique dual-phase microstructure, which combines austenite and ferrite, results in outstanding mechanical properties. These pipes boast high tensile strength (around 800 MPa) and yield strength (approximately 550 MPa), far surpassing standard austenitic stainless steels. They also show remarkable resistance to chloride-induced stress corrosion cracking, pitting, and erosion, making them ideal for high-pressure and aggressive environments. Plus, their good weldability and toughness make them perfect for demanding structural and process applications.
