Everything you need to know about Manway Gaskets

When it comes to manway gaskets, we want to keep things simple, introducing them as the small sealing ring found in hatches/openings that are constructed for large tanks. Openings which give people access to the inside of the aforementioned tanks and vessels. The...

Why Colour Matters When Choosing Gaskets?

Gasket manufacturers have turned to colour coding gaskets to make the selection and categorisation of the product more accessible.   It is possible to identify the winding and filler materials that were used for fabrication by the colouring of the outer top side of...

Choosing the Perfect Gasket for Your Needs

The perfect gasket choice and fit is an essential component of engines, appliances, and industrial machinery projects. They are a fundamental part when engineering anything from power tools to oil drills. A high-quality manufacturer of gaskets and seals will use only...

How Do You Recognise a Quality Gasket?

A gasket is a very simple item that is reasonably inexpensive. Considering how gaskets work, you may be facing a costly bill should a gasket fail. Choosing a quality gasket from Specialist Sealing Products helps to create a seal that will last until well after the...

5 Common Gasket Failures

Common Failure Causes  A blown head gasket in a vehicle is something that needs to be fixed promptly. If left untouched, you run the risk of seriously damaging your engine. Knowing what causes gasket failure or gasket problems is the key to gasket failure prevention,...

O-ring Size Guidelines

The performance of an O-ring seal depends largely on two factors— the right material and the right size. However, determining the right size O-ring is usually the hardest part when it comes to choosing the right O-ring for an application.   Unfortunately, selecting...

Tips for Proper O-Ring Installation

  An O-ring is a crucial component of a fluid system, and how it is installed can make or break that system. To ensure the success of an application, O-ring requires not only careful material selection and design but also proper installation procedures. A small...

Materials that can be Used in Producing Gaskets

Seals and gaskets are meticulously manufactured to be able to withstand the exacting conditions under which they function. Not only does a gasket seal two distinct parts and allow the containment of extreme temperature fluids, steams and gases, but it must meld the...

Manufacturing of High-Quality Gaskets

A large number of engineering and machinery applications use gaskets. This mechanical seal is employed whenever gaps between two or more surfaces are joined together. This process is also required to prevent leakage and withstand the extremes of compression when...

O Ring Materials Selection

This is a quick overview of the various O-Ring materials that are available for applications and found at select UK O-Ring suppliers. When it comes to Specialist Sealing Products, it is a good idea to be clued into every option that is on the market. The materials can...

What is a Spiral Wound Gasket?

Spiral Wound GasketFor daily purposes, gaskets are merely indispensable. Hence, it makes total sense when one thinks of having a gasket that can withstand variable fluctuations in pressure and temperature. It should also survive in situations such as flange rotation, adequate creep and bold stress relaxation, optimum flexibility and much more. This is where a spiral wound gasket comes in handy. These types of gaskets are usually manufactured in a combination of a pre-formed engineered strip of metal and a filler material; both of which must be alternating each other. In doing so, the design offers an excellent seal at the time of being compressed. In fact, the metal strip has been shaped such that it looks more like a loaded spring and that is a resilient one, under diverse situations.

Meant for multiple purposes

The spiral wound gaskets or SWGs are usually meant to fulfil a number of tasks, particularly in piping systems all over the world. Besides this, their cost is the bare minimum and stands out for extreme durability and flexibility. Another plus factor is that the use of it is not limited to any pressure class. The shape has also been made such to resist blowouts. On account of these and more, the industry has assigned the tag of ‘fire safe’ gasket to this one. Many however make a mistake of assuming that all spiral wound gaskets are the same, which is not so. It is primarily owing to metal quality, filler quality (like thickness, grade, density), machine-made or not that is capable of controlling pressure and tension on gasket winding; all of which are strong determiners of the differences in the quality of gaskets.

Common styles of gaskets used

Ideally, there are three standard styles of spiral wound gaskets, which are as follows:

  • Style D: This consists of only a sealing element (D), meant for several applications and variable conditions.
  • Style DR: This one has only a sealing element (D) and a centring ring (R), which is more of an external body that centres gasket on a primary flange face and functions as a compression stop.
  • Style DRI: This has a sealing element (D), the centring ring (R) and the inner ring (I), which helps the gasket to stay protected from any form of corrosive substance and high temperature and pressure (usually inward buckling happens for the latter).

Benefits and applications are aplenty

The fact that spiral wound gaskets have been made so rigidly is why stability is supreme. Also, their designs have equipped the gaskets to withstand the extreme level of exhaustion without showing any dip in performance. For the ideal sealing solutions in heat exchangers, utility holes, boiler hand-holes and flanged joints, this is the type of gasket that one should choose over anything else. The make is such that any form of toxin or corrosion is taken in very well by this gasket. One can browse through the different companies that stock these items like Specialist Sealing Products and thereby make a right purchase. It is only after using one will come to know the key reasons behind its immense popularity.
