Flanges Socket

Leave us a message​

Product Description:

Flanges Sockets are a type of pipe fitting used to connect pipes or equipment together. They are a type of deep-cast face that allows the pipe to be inserted and welded to the outside. The sockets come in a variety of sizes and materials, including stainless steel, carbon steel, and various alloy metals, depending on the application and working conditions.

Application:

Faceplate sockets are widely used in many industries, including:

  • Oil and gas : Used to connect pipelines in the oil and gas exploitation, transportation and processing system.
  • Chemicals : Used in pipeline treatment systems and chemical operations.
  • Energy : Applications in electrical machines and energy regeneration systems.
  • Machine generation mode : Used in piping systems of industrial equipment.
  • Build : Use for drainage and other construction applications.

Standard version :

ANSI/ASME B16.5 – Standard for Facades and Accessory Facades

Scope: This standard covers items and accessories required in system piping applications from 150 to 2500.

Dimensions: Determine dimensions, critical tolerances and size dimensions.

Materials: Specifies the types of materials that can be used, including carbon steel, alloy steel, and stainless steel.

Pressure and Temperature: Determine maximum operating temperatures and capacities for different farm types and accessories.

ANSI/ASME B16.11 – Standard for Forged, Socket Weld, and Threaded Fittings

Scope: This standard covers the required sockets and auxiliary events.

Size: Specify the name size and detailed size of the accessory.

Materials: Specifies the types of materials, mainly carbon steel and alloy steel.

Pressure and Temperature: Determine the maximum operating temperature and capacity for the accessories.
