90° buttweld elbows are engineered for maximum flow efficiency and structural
integrity in demanding industrial piping systems. Designed to change the
direction of fluid flow by 90 degrees, these fittings are essential components
for oil & gas, petrochemical, and power generation infrastructure.

90° Buttweld Elbows Types
We offer both Long Radius (LR) and Short Radius (SR) 90° elbows. Choosing the
right radius is crucial for your system’s flow dynamics and pressure drop—
