Reinforced Graphite Sheet With Metal Mesh
Description
Reinforced Graphite Sheet, it is is comprised of expanded graphite sheet and various steel sheets such uw tanged, flat or mesh. Reinforced expanded graphite sheet has character of thermally stability, high strength and no cold flow etc. Reinforced expanded graphite sheet is an ideal material of all kinds of reinforced graphite gaskets,engine heat gaskets etc. There are many kinds of reinforced expanded graphite sheet. Such as reinforced expanded graphite sheet with SS304/304L insert, reinforced expanded graphite sheet with SS316/316L, Reinforced expanded graphite sheet with tinplate insert ,etc.
Application
Made for packing rings and various kinds of gaskets
Cut into strip for filler of spiral wound gasket
Used widely in chemical, automotive and pump, valve industries

Feature:
1.High and low temperature resistance. The physical properties of flexible graphite have little changes in the non oxidizing ( from - 270 ℃ to 3650℃)，it can be used in the air up to 450 ℃.
2.Excellent corrosion resistance.Flexible graphite can be resist almost all of inorganic and organic medium except Water, sulfuric acid, nitric acid and high temperature dichromate, potassium permanganate, ferric chloride and other strong oxidizing medium.
3.Good self-lubrication.Flexible graphite, like natural graphite, the interlayer has good wearing resistance, low friction coefficient.
4.When the shaft or shaft sleeve appear radial circular runout problems , it can be sealed well with sufficient floating performance even if the graphite cracks.
5.It is a kind of economical and practical products to achieve good sealing effect with ordinary flange surface requirements and small pre-tightening force.
