An Intro to the Different Types of Pipe Flanges

Offering a reliable way to connect pipe or vessel systems, pipe flanges are the most used joining equipment. The use of flanges adds flexibility when maintaining piping systems by allowing for easier disassembly and improved access to systems components.

Flanges are not a one-type-fits-all solution matching the idle flange design to a piping system, and intended usage will ensure the reliable operation of the system. There are different types of flanges, including:

  • Blind flange: they are used to close the end of pipes or to terminate pipe systems.
  • Lap Joint: requires butt welding of the stub end to the end of the pipe.
  • Slip-On Flange: they are available in an extensive range of sizes to accommodate systems with significant flow rate and throughput.
  • Socket Weld Flange: it’s ideal for small pipe diameters in low-temperature and low-pressure systems. It utilizes a socket weld joint to attach the flange to the pipe or tube.

  • Weld Neck: Like joint flanges, weld neck flanges require butt welding to set up and assemble.

The wide range of flanges provides a basis for the reliable joining of pipes and vessels. Therefore, consider all factors before choosing the flange to use for a piping installation.
