Non-metallic Gasket

Non-Metallic Gasket

A product that is fabricated from rubber, PTFE fiber, etc is a non-metallic gasket. It is this product, that is suggested for use case in applications which are of low pressures and are flat faced. The most astonishing and beneficial fact associated with non metallic flat gasket comes from its manufacturing process. One can manufacture this product from a PTFE, elastomer, glass fibre, aramid fibre. For flat-face flanges, one an use gaskets which are full faces. Not only this, for flanges which are having raised face, it is recommended to use gaskets, which have a flat-ring.

With added benefits, one must also check for non metallic flat ring gasket to be accurate and genuine. To win over customer’s confidence, it is essential to make sure that it complies with its material standard ASME B16.21. This standard covers for broader aspects such as the tolerance, product performance, involved materials used and associated dimensional aspects.

It also covers for how it is suitable for use case with flanges, which are referred in the described standards of the flange.

One must mainly check for the below mentioned 4 important factor for getting non-degraded performance for non metallic spiral wound gasket.

  • Compatibility of the medium
  • Joint’s mechanical features
  • Gasket’s main characteristics
  • Mode of operations

Wide selection of ASME b 16.21-non-metallic gaskets for pipe flanges, additional details of non metallic gasket material cutting machine

When one considers the operating conditions, it basically coves for environmental aspects; such as pressure, temperature, soil and water erosion, etc. Medium compatibility covers for the applications which comprises, acids, beverages or materials that are corrosive. It also covers for the least possible leakage.

Other factor, joint’s mechanical feature checks for how the movement of joint angles are evaluates. One must check for how the angles for joints are calculated, and much more. In this maintenance is also covered.

For considering wider use case, ASME B16.21 non-metallic gaskets are available in varied dimensional aspects. Ideally, you would get readily stocks within NPS ½ – NPS 24 size range. Adding to this, associated inner diameter range is between 21-610mm.

But if customer demands for the specific or custom dimensions for non-metallic cut gaskets, then they should contact directly to the manufacturers. Or, if there is availability of the same from their current suppliers, they can ask for reasonable price quotations.

  • Unlike gaskets which are metallic, superior resistance to corrosion is offered by non metallic gasket sheet
  • When exposed under bolt load, you can easily perform compression for this product
  • For low pressure applications, it is a prefect choice
