Stainless Steel A403 WP347H-S 90 Degree LR Elbow Butt Weld Fitting B16.9 For Pipe Connection

ASTM A403 WP347H 90DEG LR ELBOW STAINLESS STEEL BUTT WELD FITTING B16.9

ASTM A403 WP347H 90° Long Radius (LR) Elbow is a stainless steel butt weld fitting designed to change the direction of flow in piping systems by 90 degrees. Manufactured according to the ASTM A403 specification, this fitting is made from grade WP347H stainless steel, which is an austenitic chromium-nickel steel with added columbium (niobium) for enhanced strength and resistance to intergranular corrosion.

Key Features:

• Material: WP347H stainless steel ensures excellent resistance to oxidation, heat, and corrosion, making it suitable for high-temperature and high-pressure applications.
• Design: The long radius (LR) elbow has a centerline radius of 1.5 times the nominal pipe diameter, providing smoother flow and reduced pressure drop compared to short-radius elbows.
• Angle: Changes the pipe direction by a precise 90 degrees.
• Connection Type: Butt weld ends allow for seamless and durable welding to the pipeline.
