HAKORA Sealing Technology makes Oil & Gas breakthrough with
its machined PEEK products aligning new NORSOK M-710 Compliance to ISO
The new compliance qualifies not only the resin, but also—mandatory
in this qualification process—the process and machinery used in
conversion of polyetheretherketone (PEEK) into semi-finished and
finished products, offering the highest compliance ranking of the supply
chain to the market. It is a major accomplishment as the industry
prepares for future ISO 23936-1 standards.
All tested materials passed the various NORSOK M-710 criteria, which
cover such aspects as swell, Young’s Modulus and visual inspection.
Based on these results, the qualifying institute, ‘Element™ Materials
Technology,’ was able to certify that extruded PEEK plate, PEEK rod and
PEEK tube are resistant to 10% H2S sour gas at temperatures up to 200 °C.
“NORSOK M-710 Rev3 has not yet been released, and ISO 23936-1 is
being revised, so we exposed our PEEK material to the most severe
conditions, as specified in the latest draft versions of NORSOK M-710
Rev3 and ISO 23936-2:2011. Machined test bars were exposed to 10% H2S in
100% gas phase, conditions that are five times more severe than the
sour gas phase described in NORSOK M-710 rev2.”
NORSOK and ISO standards
The NORSOK standards were developed by the Norwegian petroleum
industry to ensure safety, add value, and improve cost effectiveness of
the industry’s developments and operations. Standard M-710 defines
requirements for critical non-metallic sealing, seat and backup
materials for permanent use subsea. The standard also applies to topside
valves in critical gas systems.
The ISO 23936 (petroleum and natural gas industries – non-metallic
materials in contact with media related to oil and gas production)
standards are issued by the International Organization for
Standardization. They are separated into several sections: ISO 23936-1
(Thermoplastics), -2 (Elastomers), -3 (Thermosets) -4 (Fibre reinforced
composites) and -5 (Other materials).
