Make sure its Victrex 450G or 450GL
KC Seals manufactures the vast majority of our PEEK Back-Ups from rods and tubes that have been molded using Victrex 450G/GL granules. Victrex 450G (unfilled) and 450GL (glass-filled) PEEK materials have been thoroughly tested in conditions that meet and exceed typical exploration and production environments. These materials offer a continuous working temperature of 500°F (260°C) while exposed to hydrocarbons and/or H2S and can maintain their mechanical properties up to 572°F (300°C) in steam. In addition, Victrex 450G polymers comply with NORSOK M710/ISO 23936 test standards; in fact, the materials retained almost all of their tensile strength during each testing phase.
No other PEEK polymer has been so carefully investigated when it comes to the oil and gas sector, and that is precisely why the next time you order your PEEK backups, make sure to ask: “is it Victrex?.”
PEEK Back-up Ring Design Guide
All parts are measured on our Zeiss O-Machine and or Keyence CMM, which utilize optical and contact measurement technology in a comprehensive analysis. The O-Macine includes multi-sensor coordinate measuring, white light sensors for non-contact assessments and extremely accurate 3D scanners.
We follow AQL 2.5 levels 1 and 2 sample size quantities, and all molded parts are manufactured to RMA A2 tolerances.
Our rubber and plastic materials supply is diversified amongst the top compounders in North America. Each polymer has been qualified to meet typical exploration and production well conditions, including mechanical, tribological, thermal, and specific immersive properties.
| Material Code | Description | Heat Deflection | Tensile Strength | Tensile Elongation | Compressive Strength | Data Sheet |
| PEEK | Victrex 450G PEEK. Good toughness and impact performance, with high elongation properties. Certified to ISO 23936/NORSOK M-710 for high sour fluid ageing. | 305F | 14300 psi | 45.0% | 18100 psi |  |
| GPEEK | Victrex 450GL30 PEEK. Same features as virgin PEEK, but with higher tensile strength, as well as increased shear strength. Certified to ISO 23936/NORSOK M-710 for high sour fluid ageing. | 620F | 26000 psi | 2.7% | 37000 psi | |
| DCMS | Springing opening at the gap after splitting PEEK backups results in rejections and failures should the product be utilized in the application. Dynamic Cast Molding System™ (DCMS™) is a proprietary process that lowers inherent stress within the tube, meaning better dimensional stability and less stress. Best of all, it means no springing open at the gap. | See datasheet | See datasheet | See datasheet | See datasheet | |
