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

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.
