What Gaskets Are Best for High-Pressure Vessels?

What Gaskets Are Best for High Pressure Vessels

When it comes to the choice of gaskets on the market today, it can feel quite overwhelming to know which is the right option to use alongside high-pressure vessels. The pressure in these types of vessels can be extremely dangerous and explosive when they are not supervised properly. For that reason, the fluids must always be secured inside the seams, and so you’ll need to find a safe and reliable gasket material to use in the future. Keep reading as we discover the top gasket and seal options for your business this year.

What Type of Gaskets are Needed for High Pressure Vessels? 

When using high-pressure vessels, you’ll find that rolled sheet metal panels and welded seams have various fittings and pipes which are used to control the fluid. A gasket is needed as well to hold these plates in place and ensure the flange connectors don’t shift. The gasket must be able to accommodate the pressure feature of the vessel so that it is safe to use with the maximum variable pressure feature. Therefore, you need a material that’s both plastically and elastically designed to ensure it can expand after the fluid loading event. There are many factors that are taken into accounts, such as fluid pressure characteristics, load, and material type. This allows the gasket to perform to the best of its ability and complete the job you require from it. 

Material Options for Sealing High-Pressure Vessels 

A common question we receive is what type of material should be used for high-pressure gaskets. The metallic strength is one of the top considerations when choosing a material, and it should also be equipped with a fluoropolymer backbone compress. This will help it to keep its shape when a medium pressure scale is used. In order to enjoy good adaptability, we recommend carbon seals or mineral fibre inserts. We generally opt to use metal for high-pressure vessels, and alloy gaskets, ceramic packed rings, and pure metal rings are typically the best option. 

Alloys and ceramic materials are known for being very rigid, but pure metals are much more malleable. This gives them greater elasticity, which is usually needed for high-pressure vessels. A good gasket and seals will also have a compression feature which can be found inside an elastomeric seal. Bronze and copper are examples of softer alloys. These provide a base that’s fluid resistant, whereas aluminium and stainless steel have more strength. They still have some amount of elasticity, which means they are a great choice for a gasket and seal kit. All of these materials can handle the high temperatures and fluid pressures of the high-pressure vessels you need to use within your workplace for a safer experience. 

Solid steel is a material that many companies consider for handling fluid pressure. The dense metal ring is instead replaced with profiled metal gaskets that can handle the additional stress and pressure spikes. We also consider adding grooves and corrugated layers or jackets with a filler such as graphite. Another option that many companies are considering now is a semi-metallic gasket. This uses a V-shaped insert which offers more resilience against a high level of pressure. 

When it comes to choosing the best gasket and seal for your company, you’ll find that our team offers a wide range of spiral-wound gasket options. These high-pressure seals can be used for a wide range of applications, and we’ll be happy to share with you what would be the best choice for your business. With so many metal options and grades available today, we’ll be able to discuss if a metallic, asbestos or non-asbestos gasket is the best option for your needs. These advanced solutions we have on offer can withstand the high pressure of this type of vessel and offer the stress capacity that’s needed to smoothly seal over your vessel. There are different designs on offer as well, including a spiral wound gasket, metal jacketed basket and a ring-type gasket for different gasket use options. 

With so many high-pressure seals on offer for your vessels, it’s important you work with our team to find the right solution for your needs. We’ll be here to help you throughout the process and discuss how we can make your procedures safer and more effective in the future. Our team will work with you to go through the options that are suitable for your company, and from there, we can help to offer you a long-term solution you can use over and over again.
