Endura

Aberdeen O-Rings and Seals Ltd are official oil and gas stockists and distributors of Endura and PPE products. Precision Polymer Engineering (PPE) has been supplying high performance seals to the oilfield industry for over 30 years.

Oil exploration and extraction presents the most challenging conditions for elastomer seals; a combination of extreme temperatures, aggressive chemicals and gases, abrasive media, high pressure and destructive forces, subject seals to the harshest environments in the world.

What's more, the techniques employed to exploit reserves are constantly becoming more complex, with operations moving to more remote locations and deeper well depths, extending the operating demands on the seals even further. PPE has identified the need for a new generator of advanced materials to keep pace with the requirements of the oilfield industry.

Recognising the growing challenges that face the oil and gas exploration and extraction industry, PPE has developed the most technically advanced range of elastomer materials available.

The ENDURA™ range of elite materials has been specifically developed for use in downhole, surface and subsea oilfield equipment and offers excellent explosive decompression (ED) resistance. The range includes material grades that provide the ultimate in chemical resistance and low temperature performance for use in Arctic conditions.

Benefits of PPE sealing solutions

By combining innovative design with the latest material developments, PPE provides high performance components and sealing solutions that provide the following benefits:

Higher productivity through reduced maintenance and downtime
Increased seal life expectancy and integrity
Extended trouble-free operation with FKM materials at temperatures as low as -45°C (-49°F)
Access to the fastest production lead-times as standard, and rapid turn-round for emergency breakdown situations
Ability to react to changing conditions through access to world-class customer service and technical support
O-rings and seal components up to 2000 mm/6.5ft in diameter, fully moulded for maximum strength and durability

Rapid manufacturing lead-times

PPE understands that the oilfield industry demands the highest level of service and responsiveness. PPE's manufacturing facility contains some of the most advanced equipment in Europe, which results in rapid manufacturing capabilities and the shortest lead-times in the industry.

Technical design and consultancy service

Support and expert technical advice are always on hand at PPE. Our engineers and materials technologists are able to provide support on component design, material selection and compatibility, testing and analysis. Our consultancy service and field support includes on-site assistance with problem solving and troubleshooting.

Independent testing and analysis

Equipped with a state-of-the-art Materials Characterisation Centre and latest test apparatus, PPE's Material Technology department can provide a range of services including: material analysis, product development, characterisation, in-house high pressure testing and detailed "fingerprinting" of polymeric materials.

Assured Quality

PPE seals are manufactured to the highest quality standards. Accredited to ISO9001:2000, PPE offers full traceability on elastomer materials during every manufacturing process through to finished components.

PPE offers a range of elastomer materials to satisfy down-hole seals subjected to high temperature, high pressure and aggressive chemicals; topside piping systems and valves which must endure Arctic conditions, plus numerous subsea applications.

All ENDURA™ grades provide excellent Explosive Decompression resistance as standard.
