Universal Gaskets

Flange Gaskets

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

Flange Gaskets can be divided in major 4 different categories:

  • Sheet gaskets
  • Corrugated metal gaskets
  • Ring gaskets
  • Spiral wound gaskets

Sheet gaskets are simple, they are cut to size either with or without bolt holes for standard sizes with various thickness and material suitable to media, temperature pressure sealed element.

Ring gaskets are mostly used in offshore oil and gas pipelines and are designed to work under extremely high pressure. They are solid rings of metal in different cross sections like oval, round, octagonal etc.

Spiral wound gaskets are also used in high pressure pipelines and are made with stainless steel outer and inner rings and a center filled with spirally wound stainless steel tape wound together with graphite and Polytetrafluoroethylene (PTFE) formed in a V shape. Internal pressure acts upon the faces of the V, forcing the gasket to seal against the flange faces.

Universal Gaskets construct and supply a range of flange gaskets for all situations. Contact us for further information or to discuss your flange gasket requirements.
