What is flexitallic gasket?
The Flexitallic Spiral Wound Gasket is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes and other high temperature, high pressure applications—providing resistance to virtually every known corrosive and toxic element.
What are flexitallic gaskets made of?
Thermiculite®, FLEXITALLIC’S proprietary high-temperature, sealing material is comprised of chemically exfoliated and thermally exfoliated vermiculite.
Can you reuse a flexitallic gasket?
This type of gasket consists of a grooved metal plate with a process-compatible sealer filling the groove. Under load, the material in the groove compresses and seals the process. With proper maintenance, which includes sealer reapplication, these gaskets can be reused.
What is CG and CGI gasket?
The CGI spiral wound is the new standard spiral wound gasket per ASME B16. 20 and is required unless otherwise specified by the user. The CGI is a CG style spiral wound fitted with an internal ring which gives an additional compression limiting stop and prevents inward buckling ring.
Where are flexitallic gaskets made?
As the name implies, Flexitallic Gasket Company, nowadays headquartered in Houston, Texas, is a business specializing in the production of static sealing products.
How do you store flexitallic gaskets?
1) Store in a cool, dry area 2) Do not fold or bend. 3) If exposed to greases, oils, or solvents in liquid or vapor form, clean before installing. 4) Following extended storage, carefully inspect the material for damage. 5) Store horizontal to avoid tensions and warping (especially spiral wound gaskets).
What is a CGI style gasket?
Description. The Style CGI is for use with flat face and raised face flanges, this gasket features increased compressive force for blow-out prevention and is specified for high pressure/temperature service or where corrosive or toxic media are present.
What is FG gasket?
304 SS Spiral Wound FG, CS OR Spiral wound gaskets are metallic gaskets consisting of an outer centering ring (also known as OCR, OR, or an outer guide ring), metallic windings with a soft filler material, and a solid inner ring, or any combination of the three.
What is creep relaxation in a gasket?
In basic terms, creep relaxation is the measurement of how much a particular gasket material spreads (thins) out when force is applied. As the gasket loses thickness, the bolts can relax, which leads to a loss of load.
How do you store spiral wound gasket?
Storage
- Store in a cool, dry place.
- Do not expose gasket to excess heat or humidity or extreme fluctuations of heat and humidity.
- Keep gaskets clean and free of mechanical damage.
- Prevent dust and particulate damage.
- Avoid hanging gaskets.
What is low stress gasket?
The Spiral Wound Gasket Low Stress LSSW is designed to seal at lower stress than the conventional gasket. The required Y factor is in the range 5.000 ÷ 7.500 psi against 10.000 psi required by the standard gaskets ASME B16. 20.
What is a flexitallic spiral wound gasket?
The Flexitallic spiral wound gasket is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes, and other high-temperature, high-pressure applications—providing resistance to virtually every known corrosive and toxic element. High temperature filler material for spiral wound gaskets.
What is a flexitallic low emission gasket?
The Flexitallic Low Emission gasket is a high performance spiral wound gasket that has been specially engineered to exceed stringent oil and gas industry fugitive emissions requirements, such as those found in the Chevron Fugitive Emissions Test (CFET).
What is flexitallic manhole gasket spiral construction?
The Flexitallic manhole gasket spiral constructions incorporate modified compression values to provide seating loads within the normal range of cover assemblies. Size/Range Specification Available in circular, obround, and oval shapes to suit standard manhole plate configurations. Style T
What are the different types of exchanger gaskets?
Exchanger Gaskets with Spiral Wound Outer Ring (ALTERNATIVES HE-CG, HE-CGI) Flexitallic special HE-CGI Gaskets with spiral wound outer ring are primarily designed for TEMA male and female flanges and are custom built to suit the design conditions of individual heat exchanger vessels. These gaskets are available in an extensive range of materials.
