WHAT IS A GASKET?A gasket is a material or combination of materials essentially designed for inclusion between twostationary members of a flange joint. The primary function of any gasket is to seal effectively, forpreventing leakage of the media into the atmosphere.

The gasket material selected must be capable of sealing mating surfaces, resistant to the mediumbeing sealed, and able to withstand the application temperatures and pressures.

GASKET SELECTIONGaskets can be clearly defined into three main categories, non-metallic, semi-metallic and metallictypes. The mechanical characteristics and performance of a gasket will vary extensively, dependingupon the type of gasket selected and the materials, from which it is manufactured.Obviously, mechanical properties are an important factor when considering gasket design, but theprimary selection of a gasket type is influenced by the following factors;

Temperature of the media to be contained.Pressure of the media to be contained.Corrosive nature of the application.

NON- METALLICUsually composite sheet materials for low pressure class applications.They are suitable for a wide range of general and corrosive chemicalservices and are supplied in both non-asbestos and asbestos materials.

Types : Elastomers, Compressed Asbestos Fiber (CAF) Sheets, Non-asbestos Fiber Sheets, PTFE gaskets, Insulating Gaskets, GraphiteSheet Products.

SEMI-METALLICA composite gasket consists of both non-metallic and metallicmaterials. The metal generally provides the strength and resilience ofthe gasket. These gaskets are suitable for both low and hightemperature/pressure applications. A wide range of materials areavailable.Type : Metal Jacketed Gaskets, Spiral Wound Gaskets.

METALLICIt can be fabricated from one metal or a combination of metallicmaterials, in a variety of shapes and sizes depending on hightemperature/pressure applications.

High loads are required to seat metallic gaskets, relying on thedeformation of the material into the flange imperfections.

Type : Ring Type Joints, Lens Rings, Delta Rings, Bridgeman Rings,Serrated Gaskets, Corrugated Gaskets.

Service Conditions

Remarks(1) Maximum service temperature and pressure are not guaranteed values. Non-metallic gasket can not

be used simultaneously at both maximum temperature and maximum pressure.(2) : according to material specification.

GASKET INSTALLATION PROCEDUREIt is important that all bolted joints be tighted uniformly and in a diametrically staggeredpattern, as illustrated in below figure, except for special high pressure closures when theinstructions of the manufacturer should be followed.

- Center the gasket on the flange. This is extermely vital where raised faces are involved.Note : Standard ANSI ring gaskets, when properly cut, Should center themselves when thebolts are in place.

- Use a torque wrench and well-lubricated fasteners with hardened flat washers to ensurecorrect initial loading.

- Tighten bolts to compress gasket uniformly. This means going from side to side around thejoint in a star-like crossing pattern.

- All bolts should be tightened in one-third increments, according to proper bolting patterns.

- Retorque 12 to 24 hours after start-up, whenever possible. All applicable safety standardsincluding lockout/tagout procedure should be observed.

- Never use liquid or metallic based anti-stick or lubricating compounds on the gaskets.Premature failure could occur as a result.

BEFORE INSTALLATION- Remove old gasket and clean flange surface of all debris. For best result, use a metal flangescraper and aerosol gasket remover and a wire brush, then inspect the flange for damage. Be sure surface finish and flatness are satisfactory.

- Composition gaskets(non-asbestos,asbestos) become dried out and brittle so that they donot always provided an effective seal when reused.

- Bolted joints and flanges are designed for use with the particular type of gasket specified.Substitution of a gasket of different construction or improper dimensions may be result inleakage and damage to gasket surfaces.

- Metal or metal jacketed gaskets, when compressed initially, flow to match their contactsurfaces. In so doing they are work hardened and if reused, may provided an imprefect sealor result in deformation and damage to the gasket contact surfaces of the equipment.

- When metal jacketed type gaskets are used with a tongue groove joint without nubbin. The gasket should be installed so that the tongue bears on the seamless side of the gasketjacket. When nubbin is used, the nubbin should bear on the seamless side.

Spiral Wound Gasket (Semi-metallic)Spiral wound gaskets are to be constructed as alternate plies of preformed metal

windings(hoof) and plain fillers that are spirally wound when compressed between two

flanges. A "v" and "w" shaped crown centered in the metal strip acts as a spring, giving

gaskets greater resilience under varying conditions. Filler and strip (hoof) materials can be

changed to accommodate different chemical compatibility requirements. If the load available

to compress a gasket is limited, gasket construction and dimensions can be altered to

provide an effective seal.

A spiral wound gasket may include a centering ring, an inner ring or both. The outer

centering ring enters the gasket within the flange and acts as a compression limiter, while the

inner ring provides additional radial strength. The inner ring also reduces flange erosion and

protects the sealing element.

Resilience and strength make spiral wound gaskets an ideal choice under a variety of

conditions and applications. Widely used in refineries and chemical processing plants, spiral

wound gasket are also effective for power generation, aerospace, and a variety of valve and

special applications.

The spiral wound gasket industry is looking for change in the specification covering spiral

wound gasket. Previously, it was API 601, the new specification is ASME B16.20. Although

these specifications are very similar, KST is making the change necessary for ASME B16.20.

As environmental regulations and industry requirements become increasingly stringent,

new and custom applications are continuing to evolve. Wherever you need a strong, resilient

seal, our spiral wound gaskets provide an effective solution.

TYPE OF SPIRAL WOUND GASKET BASIC TYPEBasic construction type, inner and outer diameters are reinforcedwith several piles of metal without filler to give greater stabilityand better compression characteristics.- Suitable for tongue and groove, male and female or grooved to

flat face flange assemblies.

INNER RING TYPESolid inner metal ring acts as a compression stopper.To prevent accumulation of solids, reduce turbulent flow ofprocess fluids and minimize erosion, damages of gasket betweenflange bore and the inside diameter, the annular space is filledup by solid inner metal ring. - Suitable for male and female pipe flanges.

CENTERING RING TYPESolid centering ring accurately locates the gasket on the flangeface to give the additional radial strength to prevent the gasketblowout and acts as a compression limiter. In case of installingthe centering ring, it is very easy to install the gasket to flangeface because the end of centering ring will touch at bolts- Suitable for use with flat face and raised face flanges.

For class 900 and above an internal ring is recommended.

INNER RING and CENTERING RING TYPEA inner ring and centering ring type gasket will give anadditional compression limiting stopper for gasket inner andouter side. It will prevent the corrosions on flange face atannular space.- Suitable for use with flat face and raised face flanges and

specified for high pressure / temperature service - Class 900 and above or where corrosive or toxic media are

present.

LSS (Low Seating Stress) TYPEThe type LSS spiral wound gasket type has been engineered byKST to provide an alternative to sheet gaskets in Class 150 andClass 300 service. In case of required low load for seating, TypeLSS gaskets can give the solutions for inherent strength,resiliency and blowout resistance of spiral wound gaskets. Theyare manufactured with high purity flexible graphite filler orPTFE filler for optimum seating.- Suitable for the full range of standard class 150 and class 300

flanges, as well as other non-standard low pressure flanges.

(1) Inner rings are required for Class 900 gaskets, NPS 24; Class 1500 gaskets, NPS 12 through NPS 24; and Class2500 gaskets, NPS 4 through NPS 12.

(2) In these sizes the gasket is suitable for a welding neck flange with a standard wall bore, if the gasket and theflanges are assembled concentrically. This also applies to a nozzle. It is the user's responsibility to determine if the gasket is satisfactory for a flange of any larger bore.

(3) Gaskets in these sizes are suitable for slip-on flanges only if the gaskets and flanges are assembled concentrically.

(4) A nozzle is a long welding neck, the bore equals the flange NPS.

(5) An NPS 24 gasket is suitable for nozzles.

Recommendable the width of inner ring and inside diameter of gasket

The width of spiral wound gasket, when it iscompressed, tends to expand and a space for theexpansion is to be taken into account in design offlanges or joints.

(1) Flat or raised face is widely employed for pipeflanges and machinery joints as a gasket seatingface. Spiral wound gasket with centering ring orwith centering/inner rings is normally used onsuch flanges or joints. The following space is idealfor the gasket and it is desired to be taken into account when design new machinery andequipments.

(2) Tongue-and-groove or male-and-female flange issometimes employed in pressure vessels and valvebonnets. Basic type spiral wound gasket (without ring) is normally used for the former case and spiral wound gasket with inner ring for the lattercase. It is desired to have the following clearancefor the mentioned gaskets.

The Value of W is normally regarded as the width ofgasket sealing element. The gasket contact area Wcan be obtained in the following way.

in case of nominal gasket thickness 6.4 mmW = W - 2.0mm



The depth(f4) of tongue-and-groove or male-and-female flange must be more than 5 mm if nominalgasket thickness is 4.5mm.

Spiral Wound Gaskets based on gasket standard ofASME B 16.20a-2000 for ASME/ANSI B16.47 Series A( OF API 601- 1988 for MSS SP-44 Flanges )( OF JPI-7S-41-1998 for JPI-7S-15 Series A Flanges )

GENERAL NOTES : This table shows the maximum bore of flanges for which the spiral-wound gasket dimensions shown in belowTable are recommended, considering the tolerances involved, the possibility of eccentric installation, and thepossibility that the gasket may extend into the assembled flange bore.

NOTES :(1) Inner rings are required for all PTFE gaskets and Class 900 NPS 26 through NPS 48. (2) Applies only to welding neck flanges with a bore not larger than the inside diameter of a 0.187-in wall pipe.

Larger bores must be checked individually.(3) Applies only to welding neck flanges with a bore not larger than the inside diameter of a 0.25-in. wall pipe,

except that NPS 38, Class 300, is not suitable for a bore larger than the inside diameter of a 0.30-in.wall pipe. Larger bores must be checked individually.

(4) There are no Class 900 flanges in NPS 50 through 60.

TYPE OF METALLIC GASKET RING JOINT GASKETSolid-metal gaskets with oval and octagonal cross sectionsprovide the pressure-proof joints for high-pressure and hightemperature lines. Ring joint gaskets are identified by R, RX, orBX number that relates to flange size, pressure class, theappropriate flange standard. Irregular type ring joint gaskets such as Bridgeman ring, deltaring, double cone ring, round ring are also available with regardto customer's request. - Up to Class 20,000 psi , oil field on dirlling, petroleum equipment.

CORRUGATED GASKETIn order to give better surface contact, in which the spring effectof metal is present, the metal corrugated gasket is used in lowpressure applications that require a thin line contact because ofspace or weight limitations or where available bolt loads are low.The corrugated metal gaskets are excellent sealing effects in gas.- These are widely used in class 150 and 300 valve caps and pipe

flanges.

SERRATED GASKETSerrated gasket are manufactured using a metallic base ringmachined which concentric grooves at an appropriate angle anddepth, then covered with a soft sealing element. and give theadvantages of reducing the bolt load required to effect a seal. - These gaskets are used for high pressure/temperature steam,

gas line.

FLAT METAL GASKETThe flat surface metal gasket of simple type provides pressure-proof joints for high pressure and temperature lines.The flat metal gaskets require more bolt loads than thecorrugated and serrated gasket. - These gaskets are used for high pressure/temperature steam,

gas line, valve caps and pipe flanges, heat exchangers.

JACKETED METAL GASKETS (Semi-Metallic)The internal part of gasket is composed of an non-asbestos orglass wool or graphite millboard and the outside is jacketed bythe various thin metallic material.Various available shape are such as round, oval, non-circular, etc.- Up to Class 900, steam, water, hot water, hydrocarbon,

cryogenic line, low temperature gas, LPG

METALLIC RING JOINT GASKETRING JOINTRing joint gaskets were initially developed for use in the petroleum industry, where highpressure/temperature applications requires the need for high integrity seal.They are mainly used in the oil field on drilling and completion equipment.Ring type joints are also usually used for valves and pipework assemblies, along with somehigh integrity vessel joint.
