Fittings
Butt-weld pipe elbows in carbon, alloy, and stainless steel manufactured to ASME B16.9 and ASME B16.28. Available in 45°, 90°, and 180° configurations; short-radius (1D) and long-radius (1.5D) from ½" through 24" seamless, and 4" through 72" in fabricated welded construction. Wall thickness from Sch 10 through XXS; maximum wall 120 mm.
Applications
- → Oil & gas production and transfer lines — direction changes in flowlines and trunk pipelines
- → Petrochemical and refinery piping — high-temperature process piping in ASTM A234 alloy grades
- → Subsea pipeline laterals — 90° LR elbows for riser base tie-ins and J-tube entries
- → Power plant steam and feedwater systems — alloy grades WP11 and WP22 for elevated temperature
- → LNG and cryogenic service — low-temperature steel A402 WPL 3 and WPL 6 for cold lines
- → Offshore platform and FPSO process piping — stainless A403 grades for corrosive service
- → Large-diameter water mains and desalination distribution — welded elbows DN400–DN1800
- → Shipbuilding and marine piping — duplex and austenitic stainless steel
