A Metal Reinforced Gasket is a rigid laminated gasket consisting of soft layers bonded to each face of a solid metal core by a high temperature/chemical resistant synthetic bonding agent. While the solid metal core prevents gasket blowout, it provides high strength and rigidity: and the soft facings provide an exceptional seal. The soft facing material flows easily into the flange faces allowing a high integrity seal, even under low applied seating stresses.
The metal core material is selected to suit the application design conditions and the media to be sealed. A wide range of core materials are available, from the relatively low cost carbon steels, through the range of stainless steels up to the "exotic" alloys. For chemical resistance and temperature stability purposes, the correct core material must always be selected.
Standard core material is 316 stainless steel, and standard core thickness is 1/8".
The soft gasket facings can be Flexible Graphite, PTFE, Compressed fiber gasket material. However, Flexible Graphite is the standard and most widely used facing material supplied with the MRG gasket.
Suitable up to pressure Class 300, the Metal Reinforced Gaskets is widely used in the chemical and petrochemical industries, where a high temperature/corrosion resistant, high integrity joint is required.
"RTJ" (Ring Type Joint) gaskets are manufactured in accordance with API-6A and ANSI B16.20 specifications. RTJ's have "R" numbers assigned to them for pipe size and pressure class identification. Stock materials include soft iron, low carbon steel, 4-6 chrome (f5), 304, 304L, 316, 316L, 347, Monel, Inconel and Incoloy.
API Ring Joint GasketsAPI Ring Joint Gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10, 000 psi. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 Microinches and be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a wedging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges.
BX and RX Ring GasketsThe BX ring gasket differs from the standard oval or octagonal shape in that it is square in cross section and tapers in each corner. BX can only be used in API 6BX flanges. RX ring gaskets are similar in shape to the standard octagonal ring joint gasket but their cross section is designed to take advantage of the contained fluid pressure is effecting a seal. They are both made to API 6A.
Special Ring Type Joint GasketFor critical and non standard applications, where ring type joints are unsuitable in their standard form, FLIPS India Engineering offers a range of specialized ring type joint gaskets to suit the needs of the petrochemical industry.
Spiral Wound Gaskets are extremely popular and widely used. A spiral wound Gasket is manufactured by spirally winding a performed metal strip and a filler on the outer periphery of metal winding mandrels. The winding mandrel outside diameter forms the inner diameter of the Gasket sand superposed metal and non-metallic windings are continually wound until the required outer diameter is attained. This engineered product is tailor made to be compatible with the flange closure in which it is to be used. They can be used over the complete temperature range from cryogenic to approximately 2000 degrees Fahrenheit. This type Gasket can be used in all pressures from vacuum to the standard 2500 PSI flange ratings. They are more resilient than any other type of metallic Gasket with the exception of pressure sealing metal Gaskets and, as a consequence, can compensate for flange movement that may occur due to temperature gradients, variations of pressure and vibration.
Types of Spiral Wound Gasket
Type RBasic construction, inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. Suitable for tongue and groove or male and female or grooved to flat face assemblies.
Type RIRSolid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion of flange faces. Suitable for male and female pipe flanges.
Type CGUtilizes an external ring which accurately centers Gasket on flange face: provides additional radial strength to prevent Gasket blowout and acts as a compression stop. A general purpose Gasket suitable for use with flat face and raised face flanges.
Type CGISuitable for use with flat face and raised face flanges and specified for high pressure/temperature service or where corrosive or toxic media are present. Note on use of inner rings: ASME B16.20 which covers spiral wound Gaskets requires the use of solid metal inner rings in Pressure Class 900, nominal pipe sizes 24" and larger, Pressure Class 1500, nominal pipe sizes 12" and larger, Pressure Class 2500, nominal pipe sizes 4" and larger, All PTFE filled Gaskets
Type HEType HE Gaskets are used for heat exchangers where pass bars may be required. The outer portion is of standard spiral wound construction, whereas the rib partition is normally of single or double jacketed Type, securely fastened to the I.D. of the spiral wound portion.
Type HE-CGThis Type is identical to the Type HE, except that it is fitted with an outer guide ring.
Type HE-CGI With Spiral Wound Outer RingThe Type HE-CGI is a variation of the Type CGI spiral wound Gasket, developed for use on heat exchanger TEMA type flange arrangements. In conjunction with an inner ring, the standard spiral wound construction also supports an outer wound steel nose, designed for the purpose of accurate Gasket location. It is also available with solid metal outer ring.
Type CG-RJThis Type designates a specially sized CG Gasket to be used on standard ring joint flanges. The outer ring is dimensioned to cover the ring joint grooves and to prevent the spiral wound portion from entering the groove. This type of Gasket should be used only as a maintenance repair item.
Type 625Type 625 spiral wound Gaskets are similar to Type R Gaskets, with a thickness of 0.0625". These Gaskets are widely used wherever space restrictions indicate the need for a wafer thin Gasket design capable of sealing high pressures.
Type TThese Gaskets are used for boiler handhole and tube cap assemblies. They are available in round, oval, obround, square, pear and diamond shapes. Please note Type T Gaskets rely on internal pressure in the boiler to properly seat the Gasket. This means, when a hydrostatic test is performed on the Gasket, the pressure exerted against the plate will further compress the Gasket-and it is necessary to tighten each nut to compensate for the additional compression of the Gasket under load.
Type M, MC & MCSThese Types are designed for boiler manhole cover assemblies. They are usually round, obround or oval shape, depending of course , upon the manhole plate configuration. Type MC Gaskets have pre-formed inner and/or outer rings made of spiral windings. This centering guide permits the Gasket to assume its correct position and to compensate for inequalities in plate contours and fillets in cold-pressed plates as well as to prevent shouldering and pinching caused by radial misplacement. Type MCS Gaskets are manufactured with a solid metal inner and/or outer ring which also prevents over compression of the Gasket in high pressure systems.
A "Heat Exchanger Gasket" is a term that has been giving to the gasket that is called out for use in an exchanger. The make up of the gasket or type varies due to the operating conditions of the exchanger. Metallic gaskets can come in different types like Double Jacket, Single Jacket, Solid Metal or a Spiral Wound. Soft compressible material can be Rubber, CAF, PTFE, or Non-Asbestos Compressed sheet type.
Single Jacketed GasketsThe filler material is enclosed in a metal jacket which covers the inside and outside diameter of the gasket.
Double Jacketed GasketsThe filler material is completely enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both contact surfaces.
Soild Corrugated Metal GasketsAs the name suggests, the solid corrugated metal gasket is comprised solely of metal and does not contain any non-metallic fillers in its construction. The temperature limitation of the gasket is therefore only effected by the metal selected.
Lens Type GasketA Lens Type Gasket is a line contact seal for use in high pressure piping systems and in pressure vessel heads. The lens cross section is a spherical gasket surface and requires special machining on the flanges. In ordering lens gaskets, complete drawing and material specifications must be supplied.
Delta GasketA delta gasket is a pressure actuated gasket used primarily on pressure vessels and valve bonnets at very high pressures in excess of 5000 PSI. As with the lens gasket, complete drawings and material specifications must be supplied. Internal pressure forces the gasket material to expand when the pressure forces tend to separate the flanges. Extremely smooth surface finishes of 63 microinches or smoother are required when using this type of gasket.
Bridge-Man GasketThe bridge-man gasket is a pressure activated gasket for use on pressure vessel heads and valve bonnets for pressures of 1500 PSI and above. The cross section of the gasket is such that internal pressure acting against the ring forces it against the containing surface making a self-energized seal. Bridge-man gaskets are frequently silver plated or lead plated to provide a softer surface and minimize the force required to flow the gasket metal into the flange surface.
Weld GasketAnother gasket concept with origins from the German industrial market are weld gaskets. As standard, two variants exist; Weld Membrane Gaskets in accordance with DIN 2695 and Weld Ring gaskets.
