Types of Flanges

Blind Flange:

  • A Blind flange is a circular plate with bolt holes but no central opening.
  • It is used to seal the ends of pipes and pressure vessels, allowing for easy access for inspections.

Weld Neck Flange:

  • Weld Neck flanges have a long, tapered hub suitable for high-pressure applications.
  • They are joined to the piping system through butt welding, reducing stress concentrations and providing reinforcement.
  • These flanges match the bore of the pipe, promoting smooth fluid flow, and are ideal for high-pressure and temperature environments.

Slip-on Flange:

  • Slip-on flanges are easily fitted and welded onto pipes.
  • They provide strength and prevent leakage when welded inside and outside.
  • These flanges are cost-effective and are commonly used in low-pressure applications.

Socket Weld Flange:

  • Socket Weld flanges are attached by inserting the pipe into the socket end.
  • They offer a smooth bore, facilitating better fluid or gas flow.
  • Primarily used for smaller sizes of high-pressure pipes.

Threaded Flange:

  • Threaded flanges are similar to slip-on flanges but have tapered threads in their bore.
  • Suitable for relatively low-pressure piping systems.
  • They can be attached without welding, which is a significant advantage.

Lap Joint Flange:

  • Lap Joint Flanges slide over the pipe and are often used with stub end fittings.
  • The flange can rotate around the stub end, making it useful for applications that require frequent dismantling.
  • Typically used for smaller diameter, high-pressure requirements.
Orifice Flange:
  • Orifice Flanges are used when installing an orifice plate or flow nozzle.
  • They have pressure tappings machined into them, requiring separate orifice carriers or tappings in the pipe wall.

In addition to these common types, there are also variations such as Stub-end fittings, ss plate flanges, backup flanges, pipe flanges, Beveled ID flanges, and Reducing flanges that serve specific purposes in various piping systems. These Stainless Steel Pipe Flanges play a vital role in connecting and sealing different components within pipelines and pressure vessels.

Which flange can handle more pressure?

The Weld Neck Flange is the best choice for high-pressure applications due to its reinforced design and smooth transition, ensuring optimal pressure handling. Sanghvi Overseas, a reputable stainless steel flange Manufacturer and Supplier, provides various flanges, including blind flanges and orifice flanges, catering to diverse needs.

What is the pressure rating of Stainless Steel flanges?

The pressure rating of Stainless Steel flanges can vary depending on the specific type and size. However, they are commonly available in pressure ratings ranging from 150 to 2500 pounds per square inch (PSI). Stainless Steel Flanges Manufacturer and Supplier should customise flanges to meet specific requirements accordingly.
