WPS31254-S Stainless Steel Fittings

Stainless Steel Fittings ASTM A403 WPS31254-S 90°LR 45°LR ELBOW B16.9
 

 
1. Standard Specification: ASTM A403
 
    Stainless steel piping fittings, including elbows, tees, reducers, and caps.
    It ensures compliance with mechanical properties, chemical composition, and testing requirements.
 
2. Material Grade: WP S31254 (UNS S31254)
 
-  WP stands for "Wrought Product," indicating the fitting is made from wrought stainless steel.
-  S31254 corresponds to UNS S31254 (254 SMO), a super austenitic stainless steel with high corrosion resistance due to:
   20% Chromium, 18% Nickel, 6% Molybdenum, 0.2% Nitrogen.
- Excellent performance in aggressive environments (e.g., seawater, chlorides, acids).
 
3. Elbow Specifications
 
- 90°LR and 45°LR: Elbows with Long Radius (LR) bends.
   Long Radius (LR): Center-to-face dimension is 1.5× NPS (Nominal Pipe Size),
   reducing pressure drop and erosion compared to Short Radius (SR) elbows.
- Used to change flow direction in piping systems while maintaining smooth fluid dynamics.
 
4. Applications
  • Seawater desalination plants
  • Offshore oil & gas pipelines
  • Chemical and pharmaceutical processing equipment
  • Flue gas desulfurization (FGD) systems
  • Marine and coastal infrastructure
 
Why Choose 254 SMO (S31254)?
 
- For Critical Applications: Where failure due to corrosion is unacceptable (e.g., subsea pipelines, chemical reactors).
- Long-Term Reliability: Minimizes leaks, repairs, and system shutdowns.
- Compliance with Standards: Meets ASTM A403, ASME B16.9, and NACE MR0175 for sour service environments.
