Flanges

AP Forge Industries supplies industrial flanges used for connecting pipes, valves, equipment and other components within piping systems. Flanges provide a bolted connection that can support installation, inspection, maintenance and dismantling requirements where a detachable connection is preferred.

Our flange range can include different designs, pressure classes, face configurations, materials and dimensions according to application and project specifications. The appropriate flange is selected based on pipe size, pressure, temperature, material compatibility, connection method and applicable standard

Our Flange Range

Designed to fit over the pipe and are commonly used where installation and fabrication requirements call for a practical flanged connection
Used to close the end of a piping system, nozzle or vessel opening. Blind flanges are useful where future access, inspection or system isolation may be required
Provide a flanged connection without requiring welding to the pipe, making them suitable for selected piping applications where threaded connections are specified
Used with stub ends in systems where flange rotation and frequent assembly or disassembly can be beneficial

Special flange configurations may be used for flow measurement or other application-specific requirements where the design is defined by the project specification

Materials Available

Flanges can be supplied in material grades selected according to service conditions and applicable specifications. Depending on the product range and customer requirement, options may include:

  • Carbon Steel
  • Stainless Steel
  • Alloy Steel
  • Duplex & Super Duplex Stainless Steel
  • Nickel Alloys and other special alloys, where applicable

Final material grade should always be confirmed against the applicable standard and project requirement

Standards & Specifications

Industrial flanges are commonly specified using recognized dimensional, material and pressure standards. Depending on the product and requirement, applicable specifications may include ASME, ASTM, ANSI, MSS, DIN, EN or other project-specific standards. Flange dimensions, pressure class, facing, bore, drilling, material grade, heat treatment and inspection requirements should be confirmed for each order
