Gaskets are otherwise known as ‘seals’ or ‘joints’. Gaskets can be classified in many different ways, for example: by material, by function, or by application. A gasket is basically a part cut from a (usually) flexible material, which sits in between two other surfaces. Gaskets are typically manufactured from soft materials (such as rubber); and one of the most common uses is for sealing pipes to prevent the leakage of liquids. Gaskets also have certain other common applications, such as anti vibration and mounting.
TYPES : PIPE GASKETS, SPIRAL WOUND GASKETS, NON-ASBESTOS GASKETS, CORK GASKETS, MANWAY GASKETS, CAMPROFILE(GROOVED) GASKETS, METAL JACKETED GASKETS, RING JOINTS, FIBRE RE-INFORCED GASKETS, PTFE GASKETS, RUBBER GASKETS ETC.
Piping gaskets are made entirely of metal and rely on a seating surface to accomplish the seal; the metal’s own spring characteristics are utilized (up to but not passing σy, the material’s yield strength). This is typical of some “ring joints” (RJ) or some other metal gasket systems such as those made by Grayloc (an Oceaneering International company). These joints are known as R-con and E-con compressive type joints.
SPIRAL WOUND GASKETS
Spiral-wound gaskets comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.
These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.
Composition cork gaskets, rolls and sheets are perhaps the most versatile of all cork products. Cork rolls and cork sheets are manufactured from natural cork grains and therefore maintain most of the same characteristics attributed to cork in its natural state. Different cork grain sizes create composition cork rolls and cork sheets in grades and appearances to satisfy specific purposes and uses.
CORRUGATED METAL GASKETS
CMG Corrugated Metal Graphite (CMG) is a high performance gasket for standard flange or heat exchanger applications. The CMG molds in place by filling in irregularities of the spaces creating a superior seal. It maintains the seal even in harsh environments including hydrocarbons and steam applications. The gasket is ideal where low bolt load are present or where high gasket stresses are available. The thin profile is beneficial in areas where flange separation is limited. The heavy 22 gauge core and 1/8” pitch frequency results in superior recovery and crush resistance in the most demanding applications.
Camprofile gaskets are available in different materials, shapes and styles, including graph oil and PTFE, and can be customized to meet your individual needs. While these types of gaskets can be used without sealing layers to provide a dependable seal, they are typically used with a sealing layer for greater flange surface protection and improved sealing effectiveness.
Camprofile or “Grooved” Gaskets have proven themselves in all industrial applications. Camprofile gaskets are found in industrial power plants and in the primary circuits in nuclear installations. Used either between flanges or in heat exchanger units in nuclear applications. The Petrochemical and Chemical industries benefit too, as the gaskets are used in applications where high pressures and temperatures are maintained and consequently high bolt loads need to be controlled.
For flange protection the Camprofile gaskets are normally used in conjunction with a covering layer of either PTFE, Graphite etc, and provided that the layer thickness is correct in application the flange will be completely protected from the grooved profile of the gasket.
METAL JACKETED GASKETS
Metallic gaskets can come in different styles like; double jacket, single jacket, or solid metal. Soft compressible filler material can be flexible graphite, PTFE, or non-asbestos compressed sheet type. The design of a metal jacketed gasket also may require different shapes and the styles mentioned above can be made to a variety. Metals jacketed gaskets are normally manufactured with a high temperature filler. The standard filler is normally sufficient for applications up to 900º F. Other soft fillers are available for higher temperatures or special applications. The choice of the metal used for the jacketed part of the gasket would depend upon the corrosive conditions being encountered.
RING JOINT GASKETS
Ring Joint gaskets come in two basic types, an oval cross section (Style 377) and an octagonal cross section (Style 388). 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 micro inches and to be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a edging action as the compressive forces are applied.
The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation. Dimensions for ring joint gaskets and grooves are covered in ASME B16.20 and API6A
FIBRE RE-INFORCED GASKETS
The materials consist of fibre, fillers and binders. the percentage diversification is depending on research and development individual producer in the last time was the most used material asbestos fibres with a very small percentage of admixtures. but in present, the fibre reinforced material have only around five percent of fibres. these fibres have much bigger price than asbestos.
Level of sealing surfaces
3,2 – 12,5 μm Ra
The sealing surfaces would be in a parallel way together, so as the deviation value wasn’t greater then 0,4mm per all sealing surface. The sealing surfaces would be uniplanar, so as the deviation value wasn’t greater then 0,2mm per width of gasket.
The binder is some rubber; the commonest is NBR. For higher temperature is use combination of NBR and HNBR in the fibre reinforced material can be around ten percent of binder.
The filler is secret of each producer. it can be mineralien, chemical compound and so on. for higher temperature is possible using like filler also flaked graphite.
Aramidfibre is from aromatic amide, and has very high strength and stability for a lot of mediums. These fibres are contained in all fibre reinforced material, even though is like base used others fibre, because like unique bond others materials. others fibres look like pale.
