HOUSTON—Trelleborg Sealing Solutions recently launched XploR S-Seal and XploR FS-Seal, extrusion-resistant elastomers the company developed for demanding high temperature and high-pressure sealing environments in the oil and gas industry.
XploR S-Seal and XploR FS-Seal are custom-engineered, spring-energized seals and combine the benefits of integral support components with the flexibility of an elastomer seal.
"The standard S-Seal has been a key solution for oil and gas engineers for many years and this new version of the proven product is an enhancement to meet the ever more extreme requirements of today's oil and gas applications," said Eric Bucci, Trelleborg Sealing Solutions global technical manager for the Americas oil and gas market.
"The S-Seal is popular due to its simple one-piece design, anti-extrusion resistance and easy installation into solid grooves. Now manufactured in industry-specific XploR and incorporating an innovative anti-extrusion feature, it can operate in much higher pressures and temperatures experienced in oilfield environments."
There will be a standard range later in 2019, Bucci said. Many of the applications Trelleborg is working on require a custom-designed version. Prototypes are ordered and proposals are accepted, with first shipments scheduled for late May 2019.
Offshore oil and gas fields are moving into deeper waters, thus applications are becoming increasingly challenging. The XploR S-Seal and XploR FS-Seal are able to meet the growing demands to meet critical operating parameters, such as downhole tool applications.
"The XploR S-Seal is very versatile and is not only for downhole tools, but also for use in any static or slow dynamic applications ranging from wellheads to tubing hangers and subsea riser connections of all types," Bucci said.
"The seal can replace multi-component sealing configurations containing O-rings, back-up rings, U-cups or T-seals, for example. This makes seal installation much easier and eliminates multiple part numbers, streamlining customers' procurement and stocking processes."
The temperature and pressure limitations on the standard S-Seal depend upon the seal material and its anti-extrusion design. The XploR S-Seal is produced from an oil and gas industry-specific material that can operate at 392°F and 15,000 psi.
