Ketron® 1000 PEEK meets most severe sour gas single-phase environment conditions at high H2S levels
MCAM is first in the industry aligned to ISO 23936-2:2011 requirements
Development delivers on industry demands for materials performing in hostile HPHT environments up to 200 °C
MCAM, the global leader in machinable plastics, is further advancing industry standards by achieving NORSOK M-710 compliance for its Ketron® 1000 PEEK (natural) extruded stock shapes (plates, rods and tubes). Samples machined from the shapes performed successfully when exposed to 10% hydrogen sulphide (H2S) in 100% gas phase, as described in the ISO 23936-2:2011 standard.
The new compliance qualifies not only the resin, but also—mandatory in this qualification process—the process and machinery used by MCAM in its conversion of polyetheretherketone (PEEK) into semi-finished products, offering the highest compliance ranking of the supply chain to the market. This new breakthrough follows last year’s achievement of NORSOK M-710 multiphase compliance for MCAM’s Ketron® 1000 PEEK. 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 MCAM’s Ketron® 1000 PEEK extruded plate, rod and 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.”
For the oil and gas production industry, MCAM supplies its Ketron® 1000 PEEK natural stock shapes (produced via extrusion, injection- and compression molding techniques) for numerous applications.
The Ketron® PEEK product innovations are a demonstration of MCAM’s reinforced commitment and leadership role in continued engineering plastics processing technology advancement, and in its support of cost effectiveness in the petroleum industry for research, development and operations.
Ketron® PEEK offers a range of advanced properties that include chemical and wear resistance, combined with high temperature rating, strength and stiffness. These make it an ideal choice where performance and reliability is required in extreme and hostile environments. It is already highly valued by design engineers for use in aerospace to oilfield drilling, in the form of structural parts, bushings, bearings, seals and backup rings.
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 (Fiber reinforced composites) and -5 (Other materials).
