Problem with sealing the door gasket using nitrogen
Thread Content
Our company’s high-pressure impregnation tanks (operating at 240 degrees Celsius) are sealed using nitrogen. This is done by making grooves in the flanges connected by clamps, inserting rubber gaskets there, then tightening the clamps and introducing high-pressure nitrogen. The nitrogen pushes up on the gaskets, thereby achieving sealing. Issues: 1. We use domestically produced silicone rubber gaskets, which need to be replaced every two weeks; it is said that German gaskets only need to be replaced every two years. 2. We have also tried fluororubber gaskets, but their performance isn’t good either. Does anyone have any good recommendations?
At that temperature, both types of domestic gaskets tend to break down easily, but the German ones perform well; however, we don’t know where to find such German gaskets
