PPE Seals for Extreme Temperatures in Offshore Processing

by Aidan Towers | Jan 09, 2012
High performance seals specialist, Precision Polymer Engineering, a Unit of IDEX Corp., is

announcing its latest developments in ultra-high temperature and extreme low temperature resistant Perlast perfluoroelastomer and Endura seals for HP/HT/LT offshore applications, at Offshore Europe on Stand No. 3E80.

For continuous use at high temperatures, without loss of mechanical performance, PPE has
developed perfluoroelastomer Perlast G75TX for processes up to 327°C (621°F), together with
fluoroelastomer V91J for continuous exposure at 250°C (482°F). Overcoming the traditional
weakness of perfluoroelastomers at low temperature, all-round sealing performer Perlast G92E is
now capable of sub-zero operation down to -30°C (-22°F) at pressures up to 5,500psi.

Endura seals for demanding applications

The Endura range of oilfield elastomers has been specifically developed by PPE for use in downhole, surface and subsea oilfield equipment and offers excellent rapid gas decompression (RGD) resistance. Many of the Endura materials have been tested to international RGD standards such as NORSOK, TOTAL and NACE. Over the past 25 years, PPE has supplied O-rings and custom seals for systems operating in the most inhospitable subsea environments in the world at temperatures from -46°C (-51°F) up to +327°C (+621°F).

PPE has sales offices in Aberdeen, the US (Houston), Europe and Asia, in addition to extensive
manufacturing and technical development resources at the company's Blackburn facility in
Lancashire.
