SN Valve is a leading China butt welding 180 degrees lr return manufacturer. Butt welding 180 degrees lr return elbows are connected to the pipeline by welding and have a 180-degree bending angle and a long bending radius, hence the name long radius (LR) return elbow. The design of this elbow allows for smoother fluid flow through the pipeline, reducing flow resistance and pressure loss, while providing more space to accommodate piping layout and installation.
As the professional manufacturer, SN Valve would like to provide you high quality butt welding 180 degrees lr return. Butt welding 180 degrees lr return elbows are available in a variety of specifications and sizes to meet the needs of different piping systems. Common size ranges include a variety of inch and millimetre sizes, such as DN15~DN2000 (1/2‘~80’), and cover different pressure ratings, such as SCH 10~SCH 160 and XXS. In addition, elbows of specific sizes can be customised according to actual needs.
