Are 900 1500 gaskets the same?

All R-1 and R-3 gaskets in Classes 900 and 1500 are interchangeable within their size category.

How do I choose a gasket for my flange?

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?

In Piping Systems a Flange Gasket is placed between two connecting Flanges to create a leak proof seal. 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.

How are gaskets sized?

The Ring Gasket is the possibly the most common shape of gasket. It is also the easiest to measure. Simply measure the diameter of the inside of the circle – also called and inside diameter or I.D. Then, measure the diameter the outside of the circle, also called the outside diameter- or O.D.

What does CGI stand for in gaskets?

Style CGI – Flexible Graphite Filler (SEL) Spiral Wound Gasket Style CG with internal ring for an additional compression limiting stop, with Flexible Graphite filler material.

What is the difference between flat face and raised face flange?

The difference between a raised face and a flat face flange is that the raised face has a raised area that surrounds the pipe bore and the flat face flange doesn’t. These are two of the most commonly used types of flange faces.

What thickness gasket should I use?

Therefore the best solution is to use or design flanges with higher available compressive loads, keep the surface finish in good condition, and use 1.5 mm or even 1.0 mm thick gaskets whenever possible. Less than perfect flanges however still need to be sealed.

How many types of gasket we use?

There are three types of gaskets used in process piping….Types of Gaskets.

Non-Metallic Metallic – Ring Gasket Composite
Compressed Non-Asbestos Fibre Gasket (CNAF) Oval Ring Gasket Spiral Wound Gaskets
PTFE Gasket Octagonal Ring Gasket Camprofile Gaskets
Rubber Gasket Metal Jacketed Gasket

What is CAF gasket?

CAF/Non Asbestos Gaskets are die cut or circle cut from compressed asbestos fibre / non asbestos jointings which are manufactured from carefully selected fibre intimately blended with suitable heat resistant binders etc. and vulcanised into sheets of homogenous compositions and uniform thickness.

What are the different gasket types?

Here are the 8 types of gaskets you will see the most often:

  1. Envelope Gasket (Double Jacketed Gaskets)
  2. Flat Metal Gaskets.
  3. Non-Asbestos Sheet Material Gaskets.
  4. Ring Type Joint.
  5. Kammprofile Gasket.
  6. Spiral Wound Gaskets WITH an Inner Ring.
  7. Spiral Wound Gaskets WITHOUT an Inner Ring.
  8. Corrugated Metal Gaskets.

How do I know what size gasket I need?

When measuring a circular gasket, think of it as a clock. Use a tape measure or ruler and measure across the gasket from the 9:00 position to the 3:00 position. Measure the inside edges for the I.D. and the outside edges for the O.D. Next, count the number of BH (Bolt Holes) around the face of the gasket.
