Butt Welding 90 Degrees LR Elbow

A butt welding 90 degrees lr elbow elbow is a pipe fitting that is connected to a pipe by welding with a 90-degree bending angle and a long bending radius, often referred to as a long radius (LR) elbow. The design of this elbow allows for a smoother flow of fluid through the pipe, reducing flow resistance and pressure loss.

Socket Welded Flange

As the professional manufacturer, SN Valve would like to provide you high quality socket welded flange. Socket weld flange is a flange in which the end of the pipe is inserted into the step of the flange ring and welded at the end and outside of the pipe. It usually consists of flange body, bolt holes, sealing surface and other parts, and its structural form has two kinds of necked and non-necked. Necked socket weld flanges have good rigidity, small welding deformation and better sealing, so they are more common in practical applications.
