Product Overview
A 45° elbow is used to change the flow direction of a piping system at a 45-degree angle. Compared to 90° elbows, it creates smoother flow transitions and reduces fluid resistance. This type of elbow is commonly used in industrial pipelines requiring gradual directional changes and is available in seamless or butt-welded forms.
