Product description

Description

Flexible graphite gasket is also called expanded graphite gasket. expanded graphite without binder and filler, so high purity, good corrosion resistance. High and low temperature, good compression resilient and high strength, suitable for low voltage parts of the seal, graphite and flange to prevent galvanic corrosion between the generate.
It can be bear violent altertion of temperature and pressure. Graphite gasket is ideal gasket for valves and static seal in almost all applications.

Application

Applied to sealing parts of connection point of all kinds of pumps, pipes, valves, pressure containers, heat exchangers, tower manhole, hand-hole and flange, as well as the sealing points of nilometer ,crystallizer and liquidometer.

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.
