As it prepares for the Offshore Technology Conference (OTC) in May, Trelleborg Sealing Solutions announced that it has posted test certification for almost 30 of its best-in-class materials for the oil and gas market for the first time ever. This data is made available online at Trelleborg’s dedicated oil and gas microsite for seals, reinforcing the company’s commitment to quality and safety credentials.
The material grades are compliant with international industry standards and have been subjected to comprehensive third-party testing, qualifying materials from elastomers to PEEK- and PTFE-based compounds to a range of specifications including NORSOK M-710, ISO 23936-2, ISO 10423/API 6A Annex F.1.13.5.2 and Total GS EP PVV 142.
David Brown, Global Director, Oil & Gas at Trelleborg Sealing Solutions, said: “In today’s oilfield market, quality and safety are paramount. Simply saying you make quality products is insufficient, and claims must be reinforced with experience, compliance to industry standards, and proven performance — all of which Trelleborg Sealing Solutions has been doing for a long time.
“We are proud of the fact that Trelleborg now offers more sealing and bearing solutions for demanding oilfield conditions than any other company. We have achieved this because of our reputation. Customers know how seriously we take safety and compliance, which is why we wanted to make our test certification for a large amount of our products accessible online.”
Individual seal materials are rigorously tested and approved, both in-house and through respected third parties, based on criteria such as Rapid Gas Decompression (RGD) resistance, sour and sweet gas aging, compression set and material properties.
Two examples include the Isolast XploR J9523 and XploR V9T82, which are both compliant with the RGD and sour service aspects of ISO 23936. These “convention defying” materials are engineered to maintain excellent sealing function at very low temperatures while being subjected to high-pressure conditions. The materials – which combine these characteristics with excellent chemical compatibility – both met the ISO 23936 standard as well as revision three of NORSOK M-710.
Isolast XploR J9523 is a perfluoroelastomer (FFKM) material capable of withstanding the harshest corrosion inhibitors, brines, control line fluids and injection chemicals. Operating temperatures range from an impressive –40° to 464°F (–40° to 240°C with short excursions to 482°F (250°C).
XploR V9T82 fluoroelastomer (FKM) provides unrivalled low-temperature RGD performance down to –54°F (–48°C) with elevated resistance to methanol and acidizing agents. The elastomer operates up to 392°F (200°C) with short excursions to 410°F (210°C).
Both materials exhibit a low glass transition temperature (Tg) point, which allow the materials to remain elastic under pressure at much lower temperatures than standard grades.
Typically the Tg point of an elastomer is increased under pressure. In general, the Tg value rises by approximately 2 °F (1 °C) for every 750 psi/5 MPa increase in pressure applied. For example, a seal material with a Tg rating of –4°F (-20°C) at atmosphere will have a Tg rating of just 32°F (0°C) at 15,000 psi/100 MPa.
All approved materials are specifically engineered to meet differing operating conditions in terms of media resistance, high pressure, life expectation, friction and wear requirements. The range of compounds offered compliant to NORSOK, API and ISO and Total specifications include best-in-class Hydrogenated Nitrile Butadiene Rubber (HNBR), FKM, Isolast FFKM, Polytetrafluoroethylene (PTFE) based Turcon, TFM and PEEK.
Trelleborg Sealing Solutions will be exhibiting at OTC2017 booth #1928, which takes place May 1 through 4 at NRG Park in Houston.
