ASTM A790 UNS S32750 (Duplex 2507) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel content, suitable for both seamless and welded ferritic/austenitic stainless steel pipes. The ASTM A790 super duplex stainless steel seamless pipe is manufactured using a drawing process, with diverse production methods available.
GNEE produces pipes in various sizes and lengths. Super duplex S32750 pipes are suitable for environments with high chloride ion concentrations. Duplex UNS S32760 pipes offer high-temperature resistance up to 600°F (approximately 204°C) and exhibit low thermal expansion rates.
As a leading exporter of UNS S32750 welded pipes, our products are used in offshore oil platforms (for heat exchange piping, water treatment & supply systems, fire protection systems, sprinkler systems, hot water systems), petrochemical equipment, seawater desalination (desalination) equipment (including high-pressure piping within such systems).
Additionally, we offer super duplex hollow pipes and other special designs, such as rectangular tubes. We provide various types of welded pipes, including 1.4410 tubing and others. Please contact us for more information.
