The future of LNG seals involves shape memory alloy springs maintaining constant force across -196°C to +200°C range. API 6D valves achieve 100-year design life with these materials. Current prototypes show zero leakage after 50,000 cycles. The ball surface uses laser-textured patterns reducing seat contact area by 60% while maintaining sealing. Valves achieve self-diagnostic capabili... https://globalsealstech.com/product-category/oil-gas-seals/api-6d-ball-valve-and-lng-seals/
