Save and reliable seals for aggressive media and critical gases

Extraordinary loads on sealing materials are most often found in the oil and gas industry. Seals used with critical gases, such as natural gas containing CH4, H2S und CO2 fractions, must function safely at high pressures of up to  400 bar. If pressure is released quickly, which is customary with compressors at a rate of 100 bar/min, damage due to "explosive decompression" may occur with conventional elastomer seals. The consequential costs involved in the case of standstills/shutdowns are immense.

CREAFLEX® high-tech elastomers satisfy these extreme requirements safely and reliably and contribute to a large extent to the process safety of the production plant.

Material properties:

  • Approvals for explosive decompression (ED) by NORSOK M-710 Rev2
  • Approvals for sour gas (H2S) resistance by NORSOK M-710 ISO 23936-2, NACE TMO 187-2011 and API 6A
  • Extremely resistant to "explosive decompression“
  • Long service life
  • Very good resistance in aggressive media such as sour gas, amines, methanol, aromatic hydrocarbons
