Graphite Gasket Supplier for Compressors

Compressor - Specific Advantages

1. Dynamic Pressure Management
   • Withstands cyclic pressures up to 200 bar in reciprocating compressors while maintaining 98%+ recovery rate after decompression.
   • Low creep relaxation (<2% after 1000 hours at 150°C/100 bar) ensures long - term sealing integrity.
2. Thermal & Chemical Resilience
   • Operates reliably from cryogenic (-196°C) to superheated steam (+450°C) conditions in rotary screw compressors.
   • Resists degradation from compressor oils, refrigerants (R134a, R410A), and hydrocarbon gases.
3. Vibration & Wear Resistance
   • Graphite’s inherent lubricity reduces friction in moving components, extending seal life by 30% compared to traditional materials.
   • Compressive strength of 60 MPa resists deformation in high - torque compressor assemblies.

Applications in Compressor Technology

1. Cylinder Head Seals
   • Custom - cut gaskets for reciprocating compressors, featuring laser - etched channels to optimize gas flow.
   • Composite versions with stainless steel inserts prevent blowout in high - pressure cylinders.
2. Piston Rod Seals
   • Self - adjusting graphite packing rings maintain consistent pressure on rods, reducing leakage by 40% in continuous operation.
3. Valve Plate Seals
   • Corrugated graphite sheets create tight seals in reed and poppet valves, improving compressor efficiency by 15 - 20%.

Custom Specifications for Compressors

• Sizes:
  • Rolls: 1000mm/1500mm width, 30m/50m/80m length.
  • Sheets: 1000mm x 1500mm, thicknesses from 0.15mm (valve plates) to 3mm (cylinder gaskets).
• Density: 0.8–1.25 g/cm³ (adjustable to balance softness for rod seals vs rigidity for flanges).
