Sealing Solutions for the Oil and Gas Industry

Stable in aggressive media and under explosive decompression.

Pressure. Grease. Steam. The fields of application in the oil and gas industry place great demands on every seal’s resistance properties. The central factors that everything boils down to are efficiency and safety.

From the drill drive on the oil platform to the underwater valve; from the refinery area to the pipeline – seals in the oil and gas industry are used in the widest range of different applications. Whether drilling, pumping or processing; whether underwater or during finishing; in static or rotating applications – the production process presents extreme challenges for the materials used. And there is a central theme: the phenomenon of explosive decompression.

So it’s great that reliability is one of our greatest strengths.

Meeting your demands:

One of the greatest problems, and therefore one of the greatest demands in this sector, is the phenomenon of explosive decompression. First and foremost, this affects seals that need to seal off gaseous media when the gas sinks from high pressure to low in just a short time. Visible damage occurs, such as blisters on the O-ring’s surface or fissures in the material. This phenomenon is known by manufacturers and operators in the oil and gas industry as explosive decompression, and is as well-known as it is feared. The solution needs to be able to resist explosive decompression.

The safe choice: ISMAT AED materials

For applications in the field of natural gas production (such as pig traps, ball cocks and other types of regulating valves), ISMAT offers a wide range of tested materials that have been designed to meet the high demands of resistance against explosive decompression. (AED = Anti-explosive decompression; RGD = Rapid gas decompression.) These sealing materials have proven themselves in long-term tests in compressor construction and oil extraction. Depending on the requirements, various FKM / FKM GLT /FPM, HNBR and FFKM sealing materials are available.

All sealing materials have been successfully tested in accordance with the NORSOK M-710 standard – the decisive international standard in this area of application, and a guarantee of safety against explosive decompression.

Some of the sealing materials have additional important approvals for the industry, such as: ISO 23936-2, NACE TM0187 & NACE TM0192. Various other sealing compounds are also suitable for use in components or assemblies with API 6A & 6D in the valve industry.

Sealing Solutions for the Chemical Sector


Resistance against aggressive media, extreme temperatures, challenging environment

In the field of chemical process technology, the clear focus is on outstanding resistance. This demanding discipline is dominated by innovative production technologies and a wide range of chemicals. From liquid dosing systems to reactors, from valves to tanks; the seals used must always demonstrate formidable resistance to chemicals, extremes of temperature or extreme pressure. When all is said and done, the sealing solution must function properly, and for as long as possible.

Meeting your demands: ISMAT’s solutions

The challenges presented by the chemical industry demands a lot of different materials – which we supply. However which material presents the best solution in individual cases depends on the precise area of application. The specific one you need is therefore something that can only be answered on a case-by-case basis. But a few general aspects can nevertheless be detailed.

Out of ISMAT’s laboratory: High-performance compounds

The short form for all sealing solutions in this segment is ‘multi-talented’. With the greatest chemical resistance of all flexible sealing materials, and a wide range of certifications, ISMAT’s FFKM materials are always a strong option, especially for the chemical industry. Put quite simply: The high-tech materials in this quality grade are suitable for universal use.
Also FKM, FEPM and HNBR materials have powerful resistance compatibility in challenging media.

Further arguments for use in the chemical industry:

  • Outstanding chemical resistance
  • Good resistance to steam
  • Low compression set
  • Good mechanical properties
  • Wide range of operating temperatures
  • Large number of certifications
