Common Gaskets Type For Valve Sealing In Flanges
Flanges, as you may already know, are used to connect two pieces of pipes. Depending on the application and requirement the connection has to be very secure and leak free. This is achieved with the help of seals. It is very important to choose the right sealing material for the job. The seal must be appropriate to provide an effective seal between the material surfaces. Traditionally, dual valve seals were used very popularly but engineers often complained of these being less than ideal and causing leaks. A good face seal, spherical seal or soft seal should be able to withstand high pressures, temperatures and compressions for prolonged periods of time and what was in use was apparently not enough for the job.
A spiral wound gasket is one of the newer alternatives that offer better sealing efficiency and makes the job really easy for engineers. But spiral wound gasket is not the only type available in the market today, there are several others, and we have picked three of them particularly because they fit perfectly well with ASME flanges. That said, you need to realize that these gaskets are also applicable in other standard specifications such as ANSI and ASTM, but the ANSI being the most popular of these flange standards, it was very important for us to pick gaskets that met our criteria.
Metallic Gaskets
In cases where the seal has to be seated with high pressure to keep the contents from leaking out, this is the perfect type of seal to use. Made of metal, these seals are available in different sizes and shapes and therefore meet a wide range of market demands and applications.
Rubber Gaskets
A spiral wound gasket may also be made of rubber and other materials. The type is known as composite gasket, more about that specifically later. Some common variations of rubber you will see are Chloroprene, Silicone, and EPDM. These are applicable in environments where metallic surfaces rust or react with chemicals. These are good up to a certain temperature limit; do consult with the manufacturer for exact figures.
Composite Gaskets
These gaskets use more than one material to leverage the chemical properties of one all ingredient materials used in the manufacturing. Spiral Wound Gaskets are a type of composite gaskets. It is used extensively for high pressure and temperature environments.
Where can you find gaskets supplier?
There are several spiral wound gasket supplier, ring joint gasket supplier and other types in all metal grades and construction as well as insulation kits that you can find in the market, here in Dubai you can buy gaskets from a reputable company like Gerab, which is known for providing superior quality products. Not just that, Gerab also is one of the biggest flanges supplier in the in the middle east.
