Desirable Properties
Global Poly Systems PE3408 polyethylene piping system
provides many desirable properties for piping:
• Heat fusion joining for strong, lifetime leak free joints
• Flexibility, fatigue resistance, toughness, light weight and
impact resistance for easy, low cost installation
• Resistance to environmental stress cracking
• Resistant to surges and durable performance under
temperature extremes
• High strength and stiffness to withstand internal pressure and
external loads
• Corrosion and Chemical resistant
• Hazen Williams C Factor is 150 and doesn’t change over
time
