Ordering & Marking Information
When procuring this fitting, the complete description must include:
Standard (ASME B16.9)
Material (ASTM A234 / SA234 WP9 CL1/CL3)
Type (45° Elbow)
Radius (LR – Long Radius)
Nominal Pipe Size (e.g., NPS 6)
Schedule / Wall Thickness (e.g., Sch 80, Sch 160, or XXS)
Applications
Due to the WP9 alloy's ability to withstand prolonged exposure to high temperatures (up to ~600°C / 1100°F) and resist sulfidation and oxidizing atmospheres, this fitting is primarily used in:
Oil & Gas Refineries: Hydrocracking, catalytic reforming, and desulfurization units (high-pressure hydrogen service).
Thermal & Nuclear Power Plants: Superheater and reheater piping systems.
Chemical Processing: High-temperature heat exchangers and furnace tubes.
Sour Service: Where resistance to wet hydrogen sulfide (H₂S) cracking is required (when specified with appropriate hardness controls).
