There are many factors that can cause RGD damage. It mainly includes the following aspects: Type of gas All types of gases can cause RGD damage, but H2S and CO2 have high permeation rates, so the effects of RGD can be particularly problematic. Due to aggressive carbon dioxide and hydrogen sulfide gas, rapid gas decompression (RGD) leads to degradation and collapse of polymer components, while putt...

Rapid gas decompression (RGD) resistance is an extremely important property of elastomers in the oil and gas industry. Rapid gas decompression (RGD) often occurs when high pressure gas molecules are transferred to the elastomer under compression. When the pressure around the elastomer is suddenly released, the compressed gas in the elastomer will expand and leave the elastomer, causing RGD. When t...
