  • Socket Welding Cross

    Socket Welding Cross

    A socket welding cross is a fitting with four openings, three of which are connected to the main pipe and one of which serves as a connection for a branch pipe. Its structure is characterised by the fact that at least one of the openings is designed as a socket port, which can be inserted into the pipe and connected by welding. Socket weld cross is usually made of high quality carbon steel, alloy steel or stainless steel to ensure its high strength and good sealing performance.

  • High Pressure Butt Welding Flange

    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.
