Key Features

  • PE100 RC material compliant with fuel gas safety regulations
  • Automated butt fusion ensures zero-leak connections
  • Stub end compatible with standard ANSI/ASME flanges
  • Superior resistance to slow crack growth (SCG)

Typical Applications

  • Connection points in natural gas distribution pressure stations
  • Flange transition joints in industrial fuel gas pipelines
  • Branching interfaces in municipal gas networks
  • Termination connections for CNG/LNG station piping

Manufacturing Process

Precision injection molding + secondary thermoforming for flange

  • Melt temperature control: 200°C±5°C
  • Cooling rate gradient ≤15°C/min
  • Flange angle precision: 89°–91°
  • Fusion face surface roughness Ra≤5μm

Raw Material Characteristics

  • Density: 0.948–0.955 g/cm³ (ISO 1183)
  • Melt Mass-Flow Rate (190°C/5kg): 0.15–0.35 g/10min
  • Full Notch Creep Test (FNCT): ≥8760 hours
  • Hydrostatic design stress: 12.4 MPa/20°C/50 years
  • Spigot-flange transition at gas gate stations
  • Sealed transitions between buried and above-ground sections
  • Flange connections for gas pressure regulator skids
