What is grafoil material?

What is grafoil material?

GRAFOIL® flexible graphite is a superior performing packing and gasket material. It is the first fluid sealing material made exclusively from natural graphite flake. As a result, its resistance to corrosion, aggressive chemicals, heat and fire make it a critical sealing solution for a variety of applications.

Is grafoil and graphite are same?

The name Grafoil® is the original brand name of flexible graphite owned by GrafTech, a company founded in 1886. Grafoil® material was first introduced by Union Carbide in the 1960s. Flexible graphite is 95% – 99% carbon. It inherits many characteristics from natural mineral graphite.

What is grafoil tape?

Graphite tape is made from pure graphite. It has been pre-crinkled to allow ease in packing almost any high temperature valve. Once installed it forms an almost permanent high temperature valve stem packing for use in boiler control and pressure reducing valves.

Is graphite compatible with chlorine?

GRAFOIL flexible graphite is an extremely chemically resistant material. Unacceptable compatibility for inorganic chemicals would include molten sodium or potassium hydroxide and chlorine dioxide.

What is graphite tape?

Graphite foil tape is slit and corrugated from standard purity graphite foil. 99% graphite carbon with no filler or binder. The tape is offered with an adhesive back (2020-ZH) and without (2020-Z). Special treatments for corrosion and oxidation resistance are available upon request.

Can Garlock gaskets be reused?

Reuse of Garlock Gasket Material It is not a recommended practice to reuse a gasket. A gasket’s function is to conform to flange high and low spots when compressed, and its ability to reseal decreases after it is compressed.

What is Garlock used for?

Garlock programs for the Oil & Gas industry include solutions for on-site maintenance, turnkey emission monitoring and repair programs, Integrated Pollution Prevention Control reporting, comprehensive plant sealing, specialty projects and low emissions through the use of products such as 1303-FEP and EVSP 9000.

Is graphite non corrosive?

Graphite is corrosion-resistant against most common acids (e.g. hydrochloric acid, sulfuric acid, and hydrofluoric acid) and solvents. Although it does not affect the material’s corrosion resistance, it might affect the mechanical strength of the impervious graphite.

Is graphite chemically resistant?

Chemical properties Graphite is insoluble and infusible. It counts as one of the most chemically resistant materials.

What is grafoil gasket material?

Grafoil® Gasket Material. Flexible graphite was the first fluid sealing material made exclusively from pure, natural graphite flake and it was called Grafoil® . Its resistance to heat, fire, corrosion and aggressive chemicals make it the most universally applicable sealing solution on the market today.

How thick is a grafoil sheet?

GRAFOIL® Flexible Graphite sheets mechanically bonded to a .006″ thick sheet of 316 SS which provides a stronger gasket for corrosive services. Available in 24″ x 24″ x .062″ thick.

What is grafoil ®?
