What is Grafoil tape?
GT-786 – 1″ x 50′ Roll. 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.
What is graphite tape used for?
Flexible Graphite Crinkle Tape is heat resistant, chemical resistant, slef-lubricant, pliable, conformable, and thermal conductive. The tape can be used as form-in-place gasket, valve stem packing, pump stuffing box packing, thread seal, or other irregular shaped seal/gasket.
What is grafoil?
GRAFOIL® flexible graphite was the first fluid sealing material made exclusively from pure, natural graphite flake. Its resistance to heat, fire, corrosion and aggressive chemicals make it the most universally applicable sealing solution on the market today.
What is the difference between grafoil and graphite?
Graphite is a material that comes in an incredible range of forms and properties. Grafoil is a proprietary, flexible form of graphite for use in applications that benefit from the innate properties of graphite and that flexibility.
What is difference between graphite and grafoil?
Flexible graphite is a generic commercial term. 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.
What is gasket creep?
Creep is the loss of gasket thickness under constant load. If a compressive load were applied to a gasket sample of a given size, thickness would decrease. As the thickness decreases, the load would be allowed to remain against the gasket surface. This decrease in gasket thickness over time is defined as creep.
Which is better graphite or Teflon?
Graphite packings can be treated with PTFE to get better benefits such as preventing colour contamination, gaining better stability etc. Both graphite, as well as PTFE packings, are cost-effective as they bothare durable and require low maintenance.
What is the difference between gland packing and mechanical seal?
All Answers (4) Mechanical seal is required where zero tolerance for leakage for fluid to be sealed. Whereas the gland packing is used where leakage of fluid is used for lubrication of gland as well as no hazard or loss of fluid occur.
