What is a flange gasket?

What is a flange gasket?

A flange gasket is a gasket made to fit between two sections of pipe that are flared to provide higher surface area. ERIKS flange gaskets come in a variety of sizes and materials, Contact us to learn more about how ERIKS can help.

What gasket should you use on a flat face flange?

full-face gasket
The full-face gasket is typically used with flat face flanges but can also be used with RF flanges. It sits on the raised flange faces but has the same outside diameter of the flange. For that reason, it has to have holes for the bolts securing the flanges to pass through.

Do flanges need gaskets?

Flat Face (FF) Flanges. The Flat Face flange has a gasket surface in the same plane as the bolting circle face. 1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required.

How do I choose a flange gasket?

All of these factors must be taken into consideration when selecting a gasket:

  1. The Flange Load.
  2. Pressure in the Piping System.
  3. Temperature in the Piping System.
  4. Fluid Type.
  5. Gasket Outer Diameter.
  6. Gasket Thickness.
  7. Gasket Width.
  8. Gasket Surface Finish.

What are the different types of flange gaskets?

The three primary types of Flange Gaskets are Non-metallic, Semi metallic and Metal Gaskets. The Non-metallic Flange Gaskets are used in low pressure, low temperature and noncritical service applications.

What is the difference between a gasket and a flange?

Gaskets seal a connection between two components or flanges that have flat surfaces, while seals are used between engine parts, pumps, and shafts that rotate. Gaskets are used wherever a union or flange is required to prevent leaking.

Can you use a ring gasket on a flat face flange?

When it comes to sealing raised or flat face flanges, two types of gaskets can be used: ring and full-face gaskets. Each type is best suited for specific flange designs, so knowing the difference is important for choosing the type that will best service your application.

Can you use a spiral wound gasket on a flat face flange?

Flexitallic Style CGI Spiral Wound Gaskets Style CGI spiral wound gaskets are suitable for use on flat-face and raised-face flanges, and can be specified for high-pressure/temperature service or where corrosive or toxic media are present.

What are the three general designs of flange gasket?

Here, the softer material of the ring joint gasket is squeezed into the flanges groves as the flanges are bolted. Coupled with that, there are three styles of RTJ gaskets and these are R (oval, octagonal), RX, and BX.

What are the criteria to select a gasket?

The main conditions that must be considered without fail are fluid, temperature, and pressure. These three conditions must always be considered when selecting gaskets. Next, the shapes and dimensions (diameter, thickness, and width)of flanges need to be confirmed.

Why use Warix flange instead of Surrey flange?

Also, the Warix Flange, although a higher, better throughput, when being fitted, would allow the side mounted connector to be pointed in the direction that is required, rather than some random direction of the Surrey Flange.

How to identify Warix fittings?

To distinguish the fittings, the Warix has a flat hex top with a gasket under it, allowing the body below to be rotated before tightening. The original HW outlet from the cylinder would have probably gone straight off to the side, which is why the Surrey is silly – and the Warix was invented – I suppose.

What kind of gasket do you use for cast iron?

Use these gaskets, also known as Gore UPG, with cast iron flanges. Reinforced with a stainless steel insert, these gaskets are stronger and can hold their shape better than gaskets without an insert. Made of pure PTFE, these gaskets have a slippery surface that prevents sticking.

What is a aramid gasket?

Aramid fibers are blended with SBR rubber to resist inert gases. These gaskets also resist abrasion. Made of FDA-listed material for use with food and beverage. Also known as Gore GR. Use these gaskets, also known as Gore UPG, with cast iron flanges.
