GO Gasket Spiral Wound Ring ANSI 150 3mm Range

SKU: LGSW15015


GO Gasket Spiral Wound Ring ANSI 150 3mm Range

GO Industrial Spiral Wound Gaskets are made from a pre-formed metal strip (316 Stainless Steel) and a softer filler material (Graphite), bound together under high pressure.  The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and recovery.   
  • Size Range - 15mm - 200mm
  • Materials - 316 Stainless Steel Spiral and Graphite Filler
  • Flange - ANSI 150
  • Thickness - 3mm
  • Gasket Style - Ring
  • Maximum Temperature - + 450 deg C
  • Application - Air, Water, Low Pressure Steam, Petroleum Derivatives, Oil, Gas and General Chemical Products

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

Gaskets allow for "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials.

It is usually desirable that the gasket be made from a material that is to some degree yielding such that it is able to deform and tightly fill the space it is designed for, including any slight irregularities. A few gaskets require an application of sealant directly to the gasket surface to function properly.

A flange gasket is a type of gasket made to fit between two sections of pipe that are flared to provide higher surface area.  Flange gaskets come in a variety of sizes and are categorised by their inside diameter and their outside diameter.

There are many standards in gasket for flanges of pipes. The gaskets for flanges can be divided in major 4 different categories:

  1. Sheet gaskets
  2. Corrugated metal gaskets
  3. Ring gaskets
  4. spiral wound gaskets

Spiral-wound gaskets comprise a mix of metallic and filler material.  Generally, the gasket has a metal (normally carbon rich or stainless steel, wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.

These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.
