Generally when two metallic objects work in a position in which they are in a physical link with each other then there is a huge risk of breakage and leakage. So in a situation in which two metallic objects are working together with a physical there is a need of a gasket. Spiral wound Gasket is actually used as a filling between the two metallic objects working together. The use of gaskets results in lowering the cost for the use of machines. The filling between the mechanical objects is basically mechanical seal coating which results in long life operations of machines.
Spiral wound gasket can be manufactured with a plenty of raw material. Examples of these raw materials are silicon, rubber, paper and many more. The use of raw material for a gasket mainly depends on the type of use and the place and temperature where the gasket is supposed to be placed. For some applications gaskets may be made of asbestos. The main purpose of the gasket is to tightly fill the space including the irregularities between the two metallic objects, so it is manufactured with the material that is most appropriate according to the situation.
This type utilizes a mix of filler material and metallic material, the 2 materials are wound together forming alternating layers, they are proven to be a very reliable product in most areas however they are more expensive.
There are many different Gasket Manufacturers around, if you have a look online you will find lots of them, each have their own methods and some specialize in certain types of gaskets, make sure your find the correct type to suit your requirements.
Material
The spiral wound gaskets are manufactured with a combination or mix metallic material and filler material, normally a carbon rich stainless steel is used as a chosen material for the manufacturing of Spiral wound gaskets.
Shape
Although many other shapes can be used for the product but, the circle shape is most commonly in use.
The filler material is generally made up of flexible graphite that winds in the same directions but starting from the opposite side. The resultant product is a combination of growing circles of alternating layers of fillers and metals.
The spiral wound gaskets is an expensive product. The use of spiral wound gasket is very durable and reliable. It lasts for a very long time, hence giving the concerned user the guarantee that it is worth all the money spent on it while making its purchase. It has a strong structure, which is the prime reason for its long lasting and durable nature.
The durability of spiral wound gasket mainly depends on the mechanical characteristics of the metal strips in use, unlike the virtue of traditional comprehensive gaskets. Hence it can be easily preferred over the traditional gasket due to its great advantages.

Spiral wound gaskets provide the much required cushioning where two metallic objects are in constant contact with each other. Without the presence of a gasket, they are at risk of eroding each other in the working process. This may have serious ramifications, your machinery may fail to offer the required productivity, or you may have to replace these parts frequently. In both cases, you have to incur heavy losses. Hence, spiral wound gaskets offer much required solution in various manufacturing processes.
Spiral Wound Gasket Varieties
Raw materials used:
Different industries use spiral wound gaskets made from a varied range of materials to suit their individual requirements. Among the most widely used raw materials are: metal, plastic, silicon, rubber, asbestos and paper. While deciding on the raw material, various working conditions are taken into account like temperature, impact of chemicals, place of use etc. Apart from these factors, before deciding on any gasket variety, it is recommended that you use only those that fit in to your requirement appropriately i.e. fit into the required space tightly. The durability of spiral wound gasket mainly depends on the mechanical characteristics of the material used; hence it is one factor which should be considered carefully. Of all the metal gaskets, the carbon rich stainless steel is the most popular, for their reliability and durability in various work conditions.
Varieties in shapes:
Spiral wound gaskets are available in many different varieties depending on their respective use. There are round, rectangular, oval, diamond and pear shaped. Of these, the round or circular shaped is most widely used. They are more reliable than other shapes.
Dimensional varieties:
Most of the manufacturers of spiral wound gaskets can produce customized varieties, as per customer demands apart from those size & shape as per prevailing international standards. The same also applies to other fasteners like b7 studs, threaded rod. You can also choose the materials thickness as per your requirements. Most of the users prefer to insert a steel ring inside a spiral wound gasket to increase its efficiency. This is also helps to protect the windings (particularly the filler), from contamination, and other hazards.
Though critics of spiral wound gaskets are of the opinion that these are very expensive, they are worth the price, when you consider their beneficial factors. They go a long way in lowering risks and reducing costs. Spiral wound gaskets are the most durable sealing options in various vital industry sectors. Hence, they are used in refineries, petrochemical, chemical, steam lines and process industries, where they have many advantages over conventional gaskets.
