APPLICATIONS INDUSTRIES

A 90-degree buttweld elbow, available in long and short radius forms, is used to change the direction of flow by 90 degrees in piping systems. The long radius elbow is ideal for reducing flow resistance and minimizing pressure drop, while the short radius elbow is suitable for compact spaces. These elbows are commonly used in industries like oil and gas, petrochemical, and power generation.
