Each ASTM A815 UNS S32750 swage nipple is fabricated from super duplex stainless steel, controlled to maintain ferrite content between 35% and 60%. The fittings passed full mandatory mechanical and corrosion tests: Charpy impact test at -46°C with minimum toughness values of 45J and 35J, plus ASTM G48 pitting corrosion test performed at 50°C over a 24-hour exposure period. UT and PT non-destructive inspections were fully completed before release.
This ASTM A815 UNS S32750 swage nipple order contains mixed end forms. Some units have large-end bevel per ASME B16.25 and small-end NPT thread complying with ASME B1.20.1. Others carry double bevel ends, or reversed layout with NPT on the large end and bevel on the small end. All fittings are supplied complete with EN 10204 Type 3.2 material certification for full material traceability.
Super duplex UNS S32750 offers strong resistance to chloride corrosion, making ASTM A815 UNS S32750 swage nipple well suited for seawater, offshore and chemical processing piping widely used across Singapore and Southeast Asia. Our engineering team reviewed the mixed thread and bevel end requirements carefully to guarantee each piece meets the project’s unique connection layout.
For operators sourcing corrosion-resistant transition fittings, ASTM A815 UNS S32750 swage nipple with full NDT and corrosion test documentation can simplify site acceptance. Haihao supports custom end machining, special testing packages and full material certification for super duplex swage nipples. Contact our sales team to discuss your next piping fitting requirement.
