Our Products
INSEAL Spiral Wound Gaskets are semi metallic products designed for high pressure and temperature applications. A variety of forms of the gasket are available and these can be manufactured in various materials or sizes to suit your requirement.
With over thousands of satisfied customers in India and around the world who have procured INSEAL spiral wound gaskets, we are confident that we can meet all your service requirements
The sealing element of the spiral wound gasket consists of a V-shaped metal strip spirally wound in combination with a soft sealing material as a filler. The metal strip provides outstanding resilience, while the flexible sealing filler guarantees excellent sealing.
Due to this combination of materials, the spiral wound gasket is suitable for sealing under severely fluctuating temperature and pressure conditions. Depending on the application the spiral wound gasket can be specified with outer and/or inner rings.
When installing a Spiral Wound Gasket, check the dimensions of the Gaskets for use between pipe and pressure vessel flanges. The procedure is as follows
Measure ID of flange contact face.
Measure Gasket ID. If Gasket ID is not 1/8″ larger than flange ID, do not use it unless it can be installed perfectly centered.
A Spiral Wound Gasket does not have the same feel as other Metallic or Non-Metallic Gaskets during the bolting-up. It’s different-because it gives a little bit under each bolt as it is tightened. It is therefore important to tighten the bolts in small steps in proper sequence as shown hereunder. Final tightening must be uniform with each bolt pulling same load. This will guarantee a trouble free joint. If not uniform, the joint may leak-particularly after it has been in hot service. Tighten the bolts after 24 hours and again a week later.
CAF/Non Asbestos Gaskets are die cut or circle cut from compressed asbestos fibre / non asbestos jointings which are manufactured from carefully selected fibre intimately blended with suitable heat resistant binders etc. and vulcanised into sheets of homogenous compositions and uniform thickness. CAF/Non Asbestos cut gasket seal is effected by yielding or flow of material into the imperfections of joint contact faces. In this way gasket provides an unbroken barrier of homogenous structure through which no pathway exist for escape of confined media. Inseal International is the leading manufacturer and supplier of Asbestos Gasket in India.
Asbestos made of high qualitys long asbestos fiber, rubber and heat-resisting packing material, compressing it to thick paper.
Please refer to Asbestos Jointing Sheets to select the type of Material required depending on temperature and pressure requirements.
Non-Asbestos Jointing Sheets are made of special non-asbestos heat-resisting fiber, heat-resisting packing material, and special rubber compound heating and compression molding it.
Please refer to Non Asbestos Fibre Jointing Sheets to select the type of Material required depending on temperature and pressure requirements.
Uses:
Used in the high temperature and high pressure. For the equipment in saturated vapor, super hot vapor, gas, air, gas, ammonia alkali, and inert gases and other mediums etc. And used as sealing material in the joints of pipeline.
Rubber is perhaps the most common type of jointing.
If you application involves potable (drinking) water you will require EPDM. Please visit the EPDM Gasket Page, by following the link on the left.
If your application involves water you should consider using neoprene or EPDM. If you require a part with oil and fuel resistance, you should consider nitrile.
The properties of the gasket will depend upon the type of rubber from which it is manufactured.
Parts can be manufactured from the following rubbers: Natural, Neoprene, Nnitrile, EPDM, Silicone, Viton, Ethylene propylene, and Butyl .
Rubbers can be used in a variety of working conditions, and are typically used for water, oils, chemicals; and other low-pressure fluid applications.
Neoprene rubber gaskets(otherwise known aspolychloroprene)exhibit good chemical inertia, and are commonly used in electrical installations and weather sealing applications.
These joints are particularly suitable for use with water; be that salt or fresh water although from drinking (potable) water it is better to use EPDM rubber.
Remember that as a general rule you should select the thinnest material possible for your application.
Nitrile gasketsare particularly suited for use with fats, oils, fuels, and other liquids contaminated by these; they can also be used at a range of temperatures (-40c to +120c depending on grade).
Nitrile rubber is also known asBuna-N, Perbunan, orNBR rubber.
Remember that as a general rule you should select the thinnest material possible for your application.
Silicone rubber gaskets are known for theirchemical inertia and as such are useful inextreme environments, and temperatures from -55C to +300C.
Due to their chemical stability they are also useful in the pharmaceutical and food processing industries.
Remember that as a general rule you should select the thinnest material possible for your application.
EPDM rubber gaskets are used inanti-vibration, sealing, and electrical insulation applications.
These parts are widely used in the water industry, areWRAS approved, and sutible for use with potable drinking water.
EPDM is short forethylene propylene diene monomer rubber.
Remember that as a general rule you should select the thinnest material possible for your application.
Viton rubber gaskets are used in the presence of aggressive chemicals, fuels, and explosive gases.
Remember that as a general rule you should select the thinnest material possible for your application.
Parts are available in a range of bore sizes and tables; and either full faced (with bolt holes) or inner bolt circle (IBC or ring type joints).
Inseal International is one of the esteem manufacturers and exporters in Mumbai, India.
PTFE (Polytetrafluoroethylene) is an inert material and so has excellent chemical resistance. PTFE gaskets are mainly used in the presence of aggressive chemicals: such as acids, bases, and solvents.
Please contact us with your enquiry with dimenstions and any other specifications:
Metals are only used in the annealed condition and limit the hardness of the metal in line with international standards as shown.
