The inflatable sealing rings for pressure vessels are made from environmentally friendly silicone rubber that withstands low temperatures down to -50°C and high temperatures up to 200°C. They are suitable for industrial pressure vessel sealing requirements. These inflatable silicone rubber sealing rings and their sealing structures feature simple design, easy installation, excellent sealing performance, and the ability to achieve self-sealing in both axial and radial directions. A guide positioning ring is located on the outer edge of the inflatable sealing ring, and when the upper and lower lips on the inner edge are clamped together, they form a complete closed hollow ring. After filling the hollow ring with high-pressure gas (or liquid) inside the pressure vessel, it expands outward, generating self-tightening properties in both axial and radial directions. The greater the internal pressure of the pressure vessel, the stronger the self-tightening and the better the sealing.
