Product Description

Products Description
 

Flexible graphite materials, encompassing sheets, foil, paper, tape, and strips, are engineered specifically for compressor sealing applications. Derived from natural graphite flakes through chemical exfoliation and high - temperature expansion (producing worm - like structures with 0.003g/cc density), these materials are rolled into binder - free coils. This process ensures exceptional purity (≥99.8%) and a unique combination of properties critical for compressor performance.

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).
  • Special Features:
    • PTFE - coated variants for refrigerant compatibility in HVAC compressors.
    • Graphite - metal hybrid designs for centrifugal compressor housings.

Compliance & Testing

  • Meets API 618 (rotodynamic compressors) and ISO 10434 (reciprocating compressors) standards.
  • Tested for gas permeability (ASTM D1434), thermal conductivity (ASTM C518), and fatigue resistance (ASTM D671).
  • RoHS/REACH compliant, ensuring safe use in food & beverage and pharmaceutical compressors.
