Rapid 气体 Decompression (RGD) 测试

Within the 能源 sector, Rapid 气体 Decompression (RGD) 测试 has been a misunderstood phenomenon - until now.

Staying at the forefront of the 能源 industry developments and advancements, im体育APP offers Rapid 气体 Decompression testing to help manufacturers and users of polymeric materials better understand their behavior under these common conditions.

What is Rapid 气体 Decompression?

Caused by 气体es such as 氢 sulfide (H2S), 氢 (H2), carbon dioxide (CO2) and supercritical carbon dioxide (scCO2), Rapid 气体 Decompression causes deterioration and failures of non-metallic components, putting valuable equipment and resources at risk. Because of their constant pressure fluctuations, elastomeric seals are most vulnerable to RGD. When they are pressurized, 气体es seep into the interior of the seal, where they remain until pressure is released. 当这种情况发生时, the dissolved 气体 tries to escape, often resulting in ruptures and failures of seals and other critical components.

RGD 测试 for O-Rings using 氢 Sulfide

以前, Rapid 气体 Decompression testing had only been performed using carbon dioxide and/or methane 气体es. While these are very valuable results to have, im体育APP has developed a procedure for testing O-rings with 氢 sulfide, a highly corrosive 气体 that provides a more accurate simulation of real-world conditions. This method subjects seals to both H2S and a control (non-sour) 气体 to evaluate how sour 气体es affect the resistance to rapid 气体 decompression.  

The RGD test is conducted by applying cyclic pressure inside a pressure vessel at High Temperature/High Pressure (HT/HP) conditions as is standard procedure but with stringent H&S additions as required for this highly toxic 气体. This significant upgrade to standard methods is new and innovative, allowing the sector access to RGD testing in sour environments for the first time.
