Oil & Gas

The Oil & Gas industry presents an ever-increasing challenge with aggressive environments for equipment, and none is under more pressure than the humble seal. From high pressures and temperatures through to the need to drill deeper for oil reserves and being in constant contact with harsh chemicals, the longevity of seals is absolutely critical to the life of the equipment.

The quality and reliability of seals, be they packing, stem seals used in valves, or any other types, is crucial. They not only directly affect performance and maintenance intervals, but their integrity is vital for the safety of all who work within the vicinity. Within the Oil & Gas sector, extremes of all kinds aren’t the exception – they’re the normality.

The Challenges

The pressures placed upon seals have increased dramatically as the recovery of oil, gas, and hydrocarbons has increased in complexity. The standard seals relied upon for so long are no longer fit for purpose, meaning advanced materials and design are essential for safe and efficient operation.

Some of the challenges that seals are under include:

  • Extreme temperatures & pressures
  • Aggressive chemicals
  • Rapid Gas decompression
  • Sour gas (H2S)

The chemical environments that seals must withstand are particularly diverse, including exposure to methanol, amines, steam, supercritical CO2, hydrogen sulphide and oil.

Valve Seals, Packing Seals and Sealing Solutions for all Oil & Gas Applications

The solution for effective seals lies in the choice of material from which they are constructed along with a specific seal design. Certain polymers bring strength and longevity to seals under constant challenges from extreme conditions. These include PTFE and PEEK based materials that offer outstanding performance against the challenges of today’s production environment. The former has excellent chemical resistance and performs well at elevated temperatures, and the latter is a highly durable hard-wearing material resistant to acids, organics and bases.

Cutting-edge seal design combined with advanced material properties make for off-the-shelf and custom-designed seals that are suitable in all areas of the industry:

  • Upstream: The exploration and recovery sector demands sealing solutions that guarantee excellent performance and longevity whilst recovering hydrocarbon reserves.
  • Midstream: When processing and transporting raw natural gas and crude oil, advanced material and design seals are essential to prevent leaks, conform to legislation and – crucially –continue to do this for extended periods under duress.
  • Downstream: Processing at plants and refineries is a 24/7 process that demands seals that offer excellent MTBF. This is vital to meet environmental responsibilities and cut maintenance tasks and unexpected shutdowns that dramatically affect the bottom line in this highly competitive industry.
