CAST IRON FLANGE ADAPTOR

  1. Material:
    • Body: Cast Iron (usually ASTM A126 Class B or equivalent)
  2. Design:
    • The flange adaptor typically consists of a flanged end on one side and a plain end on the other side.
    • The flanged end is designed to match the dimensions and drilling pattern of a standard flange, allowing for a bolted connection to another flanged component, such as a valve, fitting, or another pipe.
    • The plain end is designed to fit inside a plain-end pipe or fitting, creating a secure connection when joined with appropriate fasteners, such as bolts and nuts.
    • Some flange adaptors may include a gasket or sealing mechanism to ensure a leak-tight connection between the mating surfaces.
  3. Classification:
    • Flange adaptors are classified based on their size, pressure rating, and intended application.
    • Size: Available in various sizes to accommodate different pipe diameters, ranging from small sizes (e.g., 1 inch) to larger sizes (e.g., 24 inches or more).
    • Pressure Rating: Rated for specific pressure ratings depending on the size, material, and application requirements.
  4. Description:
    • Flange adaptors are used to connect pipes or fittings with different end types, allowing for easy installation and removal without the need for welding.
    • They provide a versatile solution for joining flanged components to plain-end pipes or fittings, offering flexibility in piping system design and maintenance.
    • Flange adaptors are commonly used in water supply, wastewater treatment, HVAC, industrial, and municipal applications where a transition between flanged and plain-end pipes is required.
    • Installation of flange adaptors typically involves aligning the mating flanges, inserting the plain end into the pipe or fitting, and securing the connection with bolts and nuts.
    • Flange adaptors may be used in combination with gaskets or sealing materials to ensure a leak-tight connection, depending on the application requirements.
  5. Standards Compliance:
    • Flange adaptors may be manufactured to meet or exceed relevant industry standards and specifications, such as ASTM, ANSI, AWWA, or others, depending on the application requirements and regional regulations.
