Gasket sealing occupies a pivotal position within modern industrial enterprises. The efficacy of a seal directly impacts production continuity, asset safety, energy conservation, environmental protection, and the physical and mental well-being of personnel; consequently, the advancement of gasket technology is garnering increasing attention.
With the rise of modern industry-particularly the contemporary petroleum, chemical, nuclear energy, and large-scale power generation sectors-pressure vessels have evolved toward higher temperatures, higher pressures, high-vacuum conditions, cryogenic environments, and larger scales, while diversifying into numerous product series. This evolution continuously imposes new demands on gasket sealing systems, leading to the emergence of a wide array of novel materials and structural designs, each exhibiting vastly different sealing characteristics. Furthermore, factors such as pressure fluctuations, temperature variations, bolt preload relaxation, flange misalignment or tilting, defects in sealing surfaces, and the corrosive nature of the process medium can all significantly compromise sealing performance. Therefore, the key to ensuring effective sealing lies in correctly selecting the appropriate gasket based on specific operating conditions and executing its installation with precision.
