Our GLL flange gasket adopts advanced graphite-metal composite structure，the composite structure forms a stable chemical bond between the graphite and metal layers through molecular-level bonding technology. Achieve the synergistic effect of material performance:
GLL uses selected high-purity graphite raw materials and is modified by a patented process to give the material three core properties:
Ultra-high temperature tolerance - Maintains structural stability under extreme working conditions of 850℃ to meet the needs of harsh thermal field environments
Multi-media corrosion resistance - The lattice structure is specially strengthened to resist corrosion by acidic components such as HCl and SOx in exhaust gas for a long time
Dynamic self-lubrication function - The layered crystal structure achieves an inherent lubrication effect and effectively reduces the friction coefficient of high-temperature moving parts
GLL flange gasket metal reinforcement layer: Stainless steel or high-strength alloy is used, and it is formed by stamping integration to significantly improve the mechanical strength and deformation resistance of the gasket, ensuring long-term stability.
GLL auto exhaust pipe flange stamping gasket’s composite material system is specially optimized for exhaust gas treatment systems and shows excellent mechanical stability in thermal shock cycle tests, forming a multifunctional surface solution that integrates thermal protection, chemical barriers and motion adaptation.
Our GLL adopts a fully automatic precision stamping production line, combined with CAD/CAM technology to achieve:
High-precision molding: GLL mold accuracy reaches 0.01mm, ensuring the complete fit between the gasket and the flange surface and improving the sealing efficiency.
Customized service: Supports flexible customization of diameter (φ20-φ300mm),thickness (0.5-3mm) and shape (round, oval, special shape), suitable for the exhaust pipe design of different models.
GLL Technology highlights:
Heat treatment optimization: After stamping, vacuum heat treatment is performed to eliminate internal stress and improve material toughness.
Surface modification: Laser etching or chemical plating technology is used to enhance the oxidation resistance and wear resistance of the gasket.
Our GLL flange gasket make sure withstand the high temperature and high pressure of the exhaust system and can remain stable for a long time. Environmentally friendly sealing materials help reduce emissions and improve system efficiency.
