  • Butt Welding 180 Degrees LR Return

    Butt Welding 180 Degrees LR Return

    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.

    High Pressure Butt Welding Flange

    High quality high pressure butt welding flange is offered by China manufacturer SN Valve. High-pressure butt-welding flanges are the type of flanges that are butt-welded to the pipeline through the long neck, and their structural features include the long neck, the flange face and the welding bevel. The design of the long neck part makes the connection between the flange and the pipe stronger and can withstand higher pressure and temperature. The flange face is used to make contact with the sealing gasket to form an effective seal. The design of the welding groove is to facilitate the welding of the flange and the pipeline.
