Explosive Decompression. No problem.
High-tech compounds against explosive decompression.
The rst-class precision elastomer seals from COG are used for various industrial applications. They must fulll
highest requirements to achieve the best possible sealing result. Many manufactures and operators in the oil
and gas industries as well as in the compressor manufacturing business and in compressed air conditioning
have leakage problems with elastomer seals, especially when a drop in pressure occurs.
This primarly occurs in sealings which create a barrier against gaseous media
if highly pressurized gas falls to a very low pressure level within a very short
period of time. The result of this process is often a damage of the sealings.
The elastomer material is either torn in various places or blistering on the
surface. This phenomenon is called explosive decompression.
For the high demands on elastomer seals against explosive decompression
(AED / Anti Explosive Decompression) COG offers with eight tested compounds
a wide range of AED products which were especially developed for use in this sector. All compounds have been
tested successfully according to the NORSOK standard M-710 – the leading international standard for this
eld of application and renowned for safety for applications where explosive decompression may occur.
