3 inches Elbow 90 DEG SCH XS ASTM A234 WP91 Product Description

Category: 90 DEG 2.5D LR BW ELBOW/ASME B 16.9, Buttweld Fittings, Elbow 90 DEG
Material Grade: Alloy Steel, ASTM A234 WP91

The 90 DEG 2.5D LR BW ELBOW, designed in accordance with ASME B16.9, is a critical buttweld fitting utilized in industrial piping systems for facilitating a 90-degree directional change with a long radius (LR) bend. The “2.5D” specification denotes that the elbow’s bend radius is 2.5 times the nominal pipe size (NPS), offering a smoother transition for fluid flow compared to standard long radius elbows. This feature significantly reduces pressure drops and minimizes flow resistance, making it ideal for applications requiring gentle flow redirection to preserve fluid velocity and minimize turbulence.
Constructed from a variety of materials including carbon steel (e.g., ASTM A234 WPB), stainless steel, and alloy steel, this elbow is engineered to withstand diverse operational demands across a wide range of applications. These materials ensure the elbow’s compatibility with different fluid types while providing high strength, durability, and corrosion resistance essential for long-term service in harsh environments.
Available in sizes typically ranging from 1/2 inch to 48 inches in diameter, the 90 DEG 2.5D LR BW ELBOW can accommodate various piping system requirements. The buttweld connection ensures a secure, leak-proof joint, integral to maintaining system integrity under high pressure and temperature conditions.
This elbow is extensively used in industries such as oil and gas, chemical processing, power generation, and water treatment. Its design and construction meet the rigorous ASME B16.9 standards, making it a reliable choice for engineers seeking efficient flow control and directional change in complex piping networks.
