EVONIK: VESTAKEEP® PEEK 5000 G passes NORSOK M-710 test
March 4, 2014 + + + Evonik Industries, for decades a reliable partner
to the oil and gas industry, obtained NORSOK M-710 qualification for its
newest generation of polyether ether ketone VESTAKEEP® PEEK 5000 G. Evonik
contracted the established institute Element MERL to conduct the NORSOK
M-710 Standard aging test in sour (H2S) conditions at 1,450 psi (10 MPa)
and test temperatures of 200 °C (392°F), 210 °C (410°F) and 220 °C (428°F)
for up to 60 days (NORSOK M-710 revision 2).
The successful test
performance proves the optimal suitability of VESTAKEEP® PEEK 5000 G for
the highly demanding conditions of the oil and gas industry.
The
test result summary provides the operator with the indication of a durable
service temperature of 200 °C (392°F): No measurable chemical
deterioration for VESTAKEEP® 5000 G appeared during that period of time,
indicating that there is no degradation effect on material performance
during the expected operating time.
Furthermore, customers in the
oil and gas industry benefit from additional performance advantages of
VESTAKEEP® 5000 G like:
>
higher wear resistance
> fatigue resistance 2 to 4
times higher (depending on load)
> 15% higher
pressure creep resistance than alternative PEEK materials |
Currently NORSOK-M 710 rev 2 is the valid standard used in the oil and
gas industry.
In order to follow the needs in the oil and gas
industry and to support our customers, Evonik is presently testing
VESTAKEEP® L4000 G with the NORSOK M-710 test under rev 3, which subjects
the material to much harsher conditions.
