Today’s equipment is more reliable and well-designed than ever, so customers rely on V ring suppliers experience and knowledge to develop and manufacture technologically advanced sealing solutions. Many of the products made by V-packing suppliers are made of specific elastomer materials so they can handle harsh chemicals, high temperatures, and high pressures. The oil and gas industry is one place where these needs are apparent.
As the technology used to get natural resources has improved, so have the materials and products used to get them. This is because they need to be able to work reliably in conditions that are getting harder and harder.
Choosing Your Component
Usually, standard lip seals work well for oil and gas applications. However, when a common lip seal is not the best choice, customized lip seals and V-rings can be used as a custom, no-compromise solution.
V-packing suppliers offer engineering consulting services to help you solve your oil and gas sealing problems. The many years of experience and research have given them a deep understanding of how elastomers behave, so we can work with your in-house technicians to choose the best material for your application.
There are five main kinds of elastomers.
Five generic elastomers are used a lot in the oil and gas industry.
- Nitrile (NBR),
- Hydrogenated Nitrile (HNBR),
- Fluoroelastomer (FKM),
- Tetrafluoroethylene/Propylene (FEPM)
- Perfluoroelastomer (FFKM)
How and Why V-Rings Are So Crucial In The Oil And Gas Industry
V-ring seals are axial shaft seals that come in various sizes. This makes them very useful in many different situations. The V-ring goes right on the shaft and seals against a counter face, such as a shaft collar, thrust washer, or bearing face, in the axial direction. During their lifetime, these vital parts can handle a lot. Even when they are being put together, they are often stretched over a shaft and pushed against their seat.
Even though they can handle a small amount of pressure, their main job is to keep outside contaminants from getting into the parts of the sealing system, bearings, and other moving parts that wear quickly.
Explosive Decompression (ED), also called Rapid Gas Decompression (RGD), is a way that elastomer seals fail when gaseous media are released quickly. When high-pressure gas is put on an elastomer seal for a long time, the gas gets into the seal material. When the pressure on the outside seal goes down, the gas dissolved in the seal material comes out of the solution and forms tiny bubbles. As the gas gets bigger, it might leak through the seal material. However, if the rate of decompression (and, by extension, expansion) is high, gas trapped inside the seal can cause fissuring and failure.
Chemical Resistance in Oil Fields Side By Side
The temperature ranges are only approximations for dry air service and should not be used to determine design specifications or end-use temperature limits. In an end-use application, the actual temperature range of a compound depends a lot on the type of part, how the hardware is set up, the applied forces, the chemical medium, the effects of pressure and thermal cycling, and other things. The best way to figure out an end-use temperature range is to test it in the actual conditions of use.
The V-Ring works well on its own, but it shines when used with rotary shaft seals to make bearings, oil seals, and shafts last longer. V Ring suppliers ensure the seals work perfectly and are safer because they are made of metal.
