SEALGO® SEI Insulation Gasket, a stainless steel-epoxy composite Insulation gasket, is widely used in the oil and gas industry. Its Insulation substrate consists of a stainless steel plate bonded with epoxy glass plates on both sides: steel plate thickness 3mm, epoxy plate thickness 2mm, and total thickness 7mm. The gasket is equipped with a spring-energized seal (SES), ensuring excellent performance under cyclic pressure conditions. The seal groove is designed to reach the steel plate directly, preventing medium leakage through composite plate gaps and enabling adaptation to medium-high pressure service.
Epoxy glass plates can be selected from G10 or G11; core metal plates are available in SS316L, SS31803, SS32750, HAST C-276, INCONEL 625, etc.; spring materials for the SES can be 316 or INCONEL 718, etc.
SEALGO® SEI Insulation Gasket is suitable for 150LB~2500LB RF/FF/RTJ flanges, with a maximum manufacturing diameter of Φ1500mm.
