Gaskets and Seals

 Gaskets are principally used to stop liquid or gas spills. They give a type of a hindrance between two surfaces. It is significant for the gasket to have the option to keep a seal considerably under tension or changes in temperature. Various gaskets are accessible today. There is a precut pressure that is level and expels, and there are additionally 'framed set up' and 'relieved set up' gaskets. A few gaskets and types of gasketing can likewise be utilized to shield against electromagnetic and radio recurrence impedance.

Gaskets can be produced using an assortment of materials, so the assembling cycle of various gaskets shifts. When in doubt, gaskets are made by just cutting the correct shape from the material that can be anything from paper, silicone, elastic, metal, fiber glass, plastic polymer and felt. A few gaskets can likewise contain asbestos, when fundamental.

How does a gasket work?

A gasket is planned essentially to fit between two machine parts. It is packed between two articles so it occupies the tiny spaces, making a seal simultaneously. This seal will forestall fluid, earth and gas structures from entering the space between segments. The more grounded the pressure, the better the gasket works. Deficient tension on the seal will make the gasket slide around and open up for different pollutants to enter. This is the reason a hot pressure test is utilized to decide whether a specific gasket can withstand pressure.

By keeping these nooks liberated from earth and foreign substances, the gasket permits the apparatus to last more, give a consistent execution and work quicker and all the more productively.

Material Selection

Its very difficult to choose the right gasket for the job these days, there are just so many styles. There are many different packings with similar properties and prices. And with the ban on asbestos-based materials, there are many more styles being made to replace them. The four basic things you have to keep in mind when selecting a material are as follows: • Operating Pressure

• Bolt Load

• Resistance to chemical attack (Corrosion)

• Operating temperature

The corrosion resistance can vary based on a couple different factors: • The concentration of the corrosive agent: Higher concentrations dont always mean the fluid will be more corrosive.

• The temperature of the corrosive agent: Higher temperatures tend to speed the effects of corrosion.

• Dew Point: When the fluid moves through the dew point when in the presence of sulfer and water can result in the formation of highly corrosive condensates. The formation of sulfer and water are commonly found in gases resulting from combustion. In critical applications it is common practice to test materials in a lab to determine their chemical resistance to corrosive media under service conditions. In order to design a gasket, an evaluation is required, starting with the type of flange, bolt load, setting stress, etc. Attention to detail is key in this process and every step must be followed in order to get maximum use out of your material. Gasket selection can be simplified by using the Pressure x Temperature Factor.

Sealing why we need gaskets?

IF it was possible to manufacture flanges to be perfectly smooth and polished, and IF it were possible to maintain these surfaces in permanent contact, then we simply wouldn't need gaskets. Unfortunately this is an impossibility which results from several factors:

! The size of the vessel and/or flanges.

! Difficulty in maintaining these surfaces while handling and installing.

! Corrosion or errosion of the surface over time.

To overcome these factors we use gaskets, which fill these surface imperfections and allow for reliable fluid sealing. In order to get the optimum sealing results from your gasket, these four factors must be considered:

Seating Stress:

You first must provide an adequate sealing pressure in order to seat the gasket so it can fill the imperfections of the flange without destroying the gasket or causing it to extrude. To this end the American Society of Mechanical Engineers, or ASME, has set a minimal initial seating stress guideline in their Pressure Vessel and Boiler Code. ! Sealing Force:

You must ensure that the residual stress on the gasket after seating is adequate enough to make sure the gasket does not separate from the flange. ! Material Selection:

You must make sure that the material you are using is rated for both the pressure it will be opperating under and the fluids that are being contained by the seal.

! Surface Finish: There is a recommended surface finish for every style of gasket and every application. The leading cause of gasket leakage is the incorrect matching of a surface finish to an incompatible gasket material.

EPDM Gasket Material

Description: Ethylene Propylene Diene Monomer (EPDM): EPDM is a black plate finish sheet with superior resistance to weathering, ozone and UV exposure. EPDM also provides excellent chemical resistance*, and good electrical properties. EPDM resists animal and vegetable oils, steam, water and oxygenated solvents. This material meets ASTM D-2000-2BA specifications.

High grade material including Mil-specification is available. EPDM is also available in a white FDA approved sheet.

Typical EPDM Specifications: Excellent resistance to UV rays and ozone. Good resistance to Anti-freeze, Synthetic Detergents, Acetone, Boric acid, Ethanol, Formaldehyde, Mercury, Potassium Sulfate, Silver Nitrate, Steam (up to 212 Fahrenheit), Saccharin. For EPDM's gasket materials compatibility with your specific medium please contact American Seal & Packing.

Flexibility: This medium durometer (45-55) sheet rubber offers moderate pliability and elasticity. The harder durometer variant (55-65) offers higher abrasion resistant durability, but less pliability and flexibility.

Applications: Provides outstanding resistance to weathering, ozone and UV exposure. Gasket, bumper and general exterior applications.

Custom Cuts: In addition to hand fabrication, this product can be fabricated using laser, die, and water-jet cut. Please submit your drawings for a price quote. Available in 1/32", 1/16", 1/8", 3/16" and 1/4"

Spiral Wound Gaskets

Spiral Wound Gaskets :-

Properties And Application :-

Spiral Wound Gaskets are special semi-metallic gaskets of great resilience, there fore they are very suitable for applications featuring heavy operating conditions. Spiral wound gaskets are manufactured by spirally winding a Vshaped metal strip and a strip of non-metallic filler material. The metal strip holds the filler, providing the gasket with mechanical resistance and resilience.
Spiral Wound Gaskets can be reinforced by an outer centering ring and/or inner retaining ring. The outer centering ring controls the compression and holds the gasket centrally within the bolt circle. The inner retaining ring increases the axial rigidity and resilience of the gasket.

Spiral Wound Gaskets should always be in contact with the flange and should not protrude into the pipe or project from the flange. Spiral wound gaskets can be used for sealing flange joints, manhole and handhold covers, tube covers, boilers, heat exchangers, pressure vessels, pumps, compressors and valves; in industries such as petrochemical, pharmaceutical, shipbuilding, and food processing, in power industries and nuclear power stations. They are ideal for steam, oil, liquids, gases, acids, alkalines, various organic mediums and solvents.
ADVANTAGES of Spiral Wound Gaskets

• Sealing under heavy operating conditions.
• Strong stress compensation, stable and reliable sealing performance even
• Under frequent pressure fluctuation condition.
-Solid construction provides stability and seallability even when the sealing surfaces
• Are slightly corroded or bent. - Easy installation.

SHAPE AND CONSTRUCTION OF SPIRAL WOUND GASKETS
Spiral Wound Gaskets are produced in several styles and combination of materials to fit the most stringent application. Spiral wound gaskets are usually of circular shape, however we can produce them in other shapes such as: oval, rectangular, with round corners, etc. Our standard production program comprises a range of spiral wound gaskets with inner diameters of 10 mm to 3000 mm and a nominal thickness of 3.2 mm, 4.5 mm and 6.5 mm. Spiral wound gaskets of non-standard dimensions and shapes, and larger diameters are available on request.

Gasket standard styles: - Gaskets without guide and inner ring - Gaskets without guide and inner ring - Type S - Gaskets with inner ring – ASP-CI - Gaskets with guide (outer) – ASP-CG - Gaskets with guide and with inner – ASP-CGI
