Low emission gaskets are critical sealing components in the oil and gas industry, developed to minimize fugitive emissions and maintain strict compliance with evolving global environmental regulations. Fugitive emissions—unintended releases of gases or vapors—are a major concern due to their impact on worker safety, operational efficiency, and environmental sustainability. To address this, industry bodies such as API, ISO, and TA-Luft have established rigorous standards, including API 622, ISO 15848-1, TA-Luft, API 624, and API 641, each outlining specific qualification criteria, test cycles, and performance benchmarks for valves and associated sealing elements under demanding service conditions. Low emission gaskets are most commonly designed as spiral wound gaskets (SWG), incorporating advanced sealing elements tailored to deliver superior leak-tightness. A key differentiator from conventional spiral wound gaskets is the specialized, thicker sealing element, which is carefully engineered through precise control of filler material protrusion and thickness consistency. This design optimization significantly improves resilience against relaxation, creep, and thermal cycling, thereby creating a more reliable and durable barrier against gas and vapor leakage. The enhanced sealing element not only increases conformity to flange surfaces, but also compensates for minor flange irregularities, reducing the likelihood of leakage over long-term service. In addition, these gaskets often use high-purity graphite or PTFE fillers, sometimes reinforced with metal mesh, to improve chemical resistance, thermal stability, and low-friction sealing performance. This combination ensures that the gasket maintains integrity across a wide range of operating pressures and temperatures, including extreme conditions typical in refining, petrochemical, and pipeline applications. By integrating robust material science with precision engineering, low emission gaskets help operators meet or exceed stringent environmental regulations, reduce greenhouse gas emissions, and enhance asset reliability. Their adoption reflects the industry’s broader commitment to sustainable operations, reduced environmental footprint, and safe, leak-free performance in critical applications.
