Product Description

This is a 90-degree Long Radius (LR) Butt-Weld (BW) Elbow, manufactured in accordance with ASME B16.9. It is made from ASTM A234 Grade WPB carbon steel, with a seamless (SMLS) construction. The elbow has a nominal size of 4 inches and a schedule thickness of SCH 80. Its long radius design (1.5 times the nominal pipe size) provides smooth flow transition with minimal pressure drop.

Typical Application

Widely used in high-pressure and high-temperature piping systems across industries such as petrochemical, oil and gas, power generation, and refinery plants. It is ideal for changing the direction of fluid flow in pipelines where a strong, leak-resistant, and permanent welded joint is required. The SCH 80 wall thickness makes it suitable for applications that demand extra mechanical strength and corrosion resistance under severe service conditions.
