Supagraf Premier hasenvironment a record general economic of beating fugitive emission control specifications.

In 1997 it was subjected to over For more news, products, services and latest 12,000 valve operating cycles with methane at 40bar and kept emission levels below 500ppm.

Anyone for golf?

In 1999, it came top of its class in comparative tests run by the Materials Technology Centre of Akzo Nobel. Leakage rates were between six and 100 times less than competitors’ brands — and it lasted 12 times longer than the next best valve packing.

You can visualise this as less gas than will fill a golf ball in a year, measured at ambient pressure.

Since then it has twice been certified to TA-Luft requirements by different customers, and third-party verified for emission control by CETIM to Shell SPE 77/321 Class A specification.

The test cycle involved 1000 vertical valve stem movements of 40mm — without live-loading on the packing — whilst sealing helium at 25bar for 24 hours. Leakage measurements after 24 hours at 240°C showed 7.0 x 10-6 mbar.l/(s.m).

It also demonstrates that Supagraf Premier very easily meets TA-Luft requirements for a high grade valve packing. After 24 hours at 400°C, the leakage rate was 2.3 x 10-5 mbar.l/ (s.m).

With testing to establish the limits of the new polymer architecture still ongoing, FR68/90 has already exceeded Norsok compliance specifications, achieving a perfect test result not only at 8.40mm section at 100°C but also at 5.33mm section at an elevated temperature of 150°C. This enhanced RGD performance is not achieved at the expense of other material characteristics however.

Hopefully the benefits of these, FR68/90 retains flexibility for in combination with further ease of fitting and offers excellent investments planned for 2009, sealability with compression set figures of just 8% after 24 hours @ +175°C and 10% after 24 hours @ +200°C. Add to this, superb Amine and H2S resistance plus an operational temperature capability of -30°C to +200°C and FR68/90 has the capability to take elastomeric sealing into new territory, extending the use of elastomeric materials to larger sections than previously possible with no loss of RGD resistance – a factor that can eliminate the need for complex and costly reengineering of components to accept physically larger solutions such as spring energised PTFE seals.
