Buttweld Bend Pipe is utilized to change the direction of a pipeline. It is designed to have a smooth inner surface in order to reduce pressure drop and prevent any interruption in the flow of fluids. Butt weld bend pipes are made by cutting, bending, and welding pipes with the same size and schedule. This pipe is generally made by bending a straight pipe to a desired angle, typically 90 degrees or less, and then welding the two ends of the bent pipe together.
