Six common flange gasket used in pipeline-Graphite gasket

Solid metal serrated gasket is to machine a bevel-shaped corrugation on the sealing surface of the metal flat gasket – suitable for the MFMflange sealing surface;Get more news about Flange Metallic Gasket,you can vist our website!

Lens Ring gasket – suitable for lens flange sealing surfaces.

Metallic gaskets are available in a variety of materials such as pure iron, very mild steel, stainless steel, and aluminum.

Metallic gasket sealing surface has high requirements for processing precision and surface roughness.The bolts have a large pressing force and are used in high temperature and high pressure valves.It is made of a thin metal coated ring asbestos gasket.Generally used in the MFM flange sealing surface and is suitable for high temperature and high pressure valves.

The most widely used composite type gasket is a spiral wound gasket.Spiral Wound Gaskets are manufactured by spirally winding a V shaped metal strip and a strip of non-asbestos filler material.The metal strip holds the filler, providing the gasket with mechanical resistance and resilience. Spiral wound gaskets can be reinforced by an outer centering ring and/or inner retaining ring.It is generally used for MFM flange sealing surfaces and is suitable for high temperature and medium pressure valves.

It is generally used for the TF and GF sealing surface.There are mainly two kinds of materials: PTFE and glass fiber PTFE. It is suitable for highly corrosive media of lower temperatures and various pressures.

Asbestos rubber gaskets include universal asbestos sheets and anti-corrosion asbestos sheets, and generally use asbestos sheets, acid-resistant asbestos sheets, oil-resistant asbestos sheets, and metal wire asbestos sheets.It is suitable for higher temperature and medium pressure valves.

It is suitable for FF sealing surface,MFM sealing surface and TF and GF sealing surface.Advantages: good corrosion resistance and thermal stability,good plasticity,and sealing with a small pressing force.
