Basic about Flanges and selecting flange types

Offering a reliable way to connect pipe systems with the various equipment, valves, and other components of virtually any machining system, flanges are the second most used assembly method after welding.

A typical flange connection consists of three parts :

  • Pipe Flanges.
  • Gasket.
  • Bolting.

In many cases, there are particular gaskets and bolting materials made out of the same or approved materials as the piping components you need to connect. Stainless Steel Flanges are the maximum popular ones. Therefore, flanges are to be had in an extensive variety of materials, so it’s miles crucial to tailor them to your wishes. The correct alternative in your bridle wishes will depend on each gadget you intend to apply the bridle to and your specific needs.

Characteristics of Stainless SteelĀ  Flanges

  • Corrosion-resistant
  • High tensile strength
  • Very durable
  • Temperature resistant
  • Easy formability and fabrication
  • Low-maintenance (long-lasting)
  • Attractive appearance
  • Environmentally friendly (recyclable)

Types of Flanges

  • Threaded Flanges- Also called screwed flange, It has a thread inside the flange bore that fits with the matching male thread on the pipe. The threaded connection avoids welding in many use cases. Simply match the threading to the pipes you wish to connect.
  • Socket-Weld – Flanges are perfect for smaller pipe diameters in low-temperature and low-pressure scenarios, socket-weld flanges feature a connection as you insert the pipe into the flange, then secure the connection with a single multi-pass fillet weld. This makes this style easier to install than other types of welded flanges, avoiding the limitations associated with threaded ends.
  • Slip-on Flanges- Slip-on flanges are very not unusual to place and are to be had in a big variety of sizes to deal with structures with better float prices and throughput. Simply model the flange on the outside diameter of the pipe you want to connect.
  • Weld Neck Flanges- Like lap joint flanges, weld neck flanges require butt welding for installation. Therefore, their integrity, performance in systems with multiple repeat bends, and the ability they use in high pressure and high-temperature systems make them a prime choice for process piping.
  • Blind Flanges-Used for terminating or isolating piping systems, blind flanges are essentially boltable blank discs.
