Oil & Gas

The extreme demands placed on equipment within the Oil and Gas industry require high standards of reliability, operational best practice and leading-edge technical expertise. These strict requirements make AESSEAL® the natural fit for the industry.

Meet Emission Targets with Low Capital Expenditure

Many plants face increasing pressure to upgrade old equipment, typically API610 Ed.5 to Ed.7 to conform to increasingly tighter emission legislation. This creates a considerable plant CapEx burden.
AESSEAL® can retrofit API682 qualification tested seal face technology to mature assets. This allows you to get world-class seal emission levels without replacing or modifying the old equipment.

Fix Known Fire and Safety Risks

The radial clearances between the counter-rotational parts in a Plan 23/52/53 seal are often reduced by seal suppliers so that conventional seal pumping rings can function. This carries well-documented safety risks, including danger to operators and the possibility of fire. 
AESSEAL® has world-leading bi-directional pumping ring technology which delivers exceptional flow while fully conforming to the best-practice radial clearances stated in API682 Ed.3 Section

Drastically Reduce Equipment Failures From Sand and Waxy Crude

Sand and waxy crude are major causes of mechanical seal failure during extraction and oil processing. The cause of failure is typically clogged seal springs positioned in the process media. Unfortunately nearly all API682 mechanical seals found on the market today share this design flaw.

AESSEAL® API seal designs have multiple springs that do not contact the process fluid. This eliminates all possibility of seal face hang-up or seal failure from spring clogging, significantly increasing mean-time between failure, even with high crude consistencies or solids content.

In addition to common-sense mechanical seal solutions, AESSEAL® offers a range of innovative Oil & Gas Seal Support Systems, from Plan 75: gas containment systems toPlan 53C: pressure tracking systems. We also manufacture bearing protection certified to IP66 and API610 Section 5.1.25 and refurbish any make of Dry Gas Seal to API617.

The petrochemical industry transforms crude oil and natural gas into products and raw materials. Petrochemical plants use the by-products from the refining process to produce every day products such as plastics, ethylene and fertilizers.

Due to the vast number of products produced by this industry there are many different plants and production processes. Whatever your processes, AESSEAL® prides itself on providing increased reliability solutions.


Downstream is a term commonly used to refer to the refining of crude oil and the selling and distribution of natural gas and products derived from crude oil.

As many as 2,300 different products can be processed through a refinery. Typically the refined products are used in:

  • Fuels for vehicles
  • Fuels for the generation of heat and power
  • Raw materials for the petrochemical and chemical industries
  • Speciality products such as lubricating oils, paraffin, waxes and bitumen
  • Energy

Variation in product type, the available crude quality and requirements set by authorities mean that no two refineries are the same. To meet your specific needs the modular nature of our inventory means that we can quickly adapt our range to the application requirements of each refinery.


Upstream is a term commonly used to refer to the search for, and recovery and production of, crude oil and natural gas.

The sector is also known as the exploration and production (E&P) sector.
