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 Thermiculite gasket?
Thermiculite® 835 is a critical service gasket designed for use in applications involving high temperatures and/or aggressive chemical media. It is comprised of a spirally wound sealing element composed of a metal winding wire in combination with a vermiculite based filler material.
What is Thermiculite?
Description. Thermiculite® 815 is a high temperature, chemically resistant sheet sealing material comprising of exfoliated vermiculite reinforced with a tanged. stainless steel core. Thermiculite® 815 provides total freedom from oxidation. Chemical compatibility exceeds graphite.
What are flexitallic gaskets made of?
Thermiculite®, FLEXITALLIC’S proprietary high-temperature, sealing material is comprised of chemically exfoliated and thermally exfoliated vermiculite.
What is m and y values for gaskets?
m represents the maintenance factor and the y represents the seating stress. y is the minimum compressive stress on the contact area of the gasket necessary to provide a seal at an internal pressure of 2 psig and applied to compress the voids of the gasket to conform to the flange surface.
How many times can a 6b ring gasket be used?
This gasket must be utilized only one time. The “RX” gasket is compatible for 6BX flanges and 16B hubs.
What is Thermiculite made of?
Thermiculite® 815 is a high temperature, chemically resistant sheet sealing material comprising of exfoliated vermiculite reinforced with a tanged stainless steel core.
How thick is a flexitallic gasket?
All CG and CGI Gaskets for these standard flanges are 0.175 in (4.5mm) thick, fitted with 0.125 in (3.2mm) thick solid metal rings, unless otherwise stated.
How thick is a spiral wound gasket?
The standard manufacturing thicknesses for spiral wound gaskets are: 3.2 mm; 4.5 mm; 6.5 mm (measured across metallic strip not including the filler, which protrudes 0.2 – 0.3 mm beyond the metal).
What is M in gasket?
The “M” value allows the flange designer to determine the compressive load on the gasket required to maintain a seal when the vessel is pressurized. The flange must have sufficient strength and bolting to hold the joint together against the hydrostatic end force, and to apply some additional “net stress” on the gasket.
What kind of fibres are in flexitallic AF 2100?
FLEXITALLIC AF 2100 is reinforced with glass fibres based on continuous filaments of controlled diameter well above the size recognised as respirable. Consequently this material contains NO RESIRABLE FIBRE. Under harsh mechanical treatment (e.g. high speed stamping operations or abrasion) or if the…
Can you use a gasket paste with AF 2100?
Do NOT use gasket pastes. The higher compressibility of AF 2100 compared to CAF combined with the comparative effects of thickness on residual stress means that AF 2100 should be used at lower thicknesses. It is recommended that 1.0 mm AF 2100 be used in place of 1.5 mm CAF.
