Product Characteristics

The Snap-Tite joint is machined on the ends of PE 3408 high density polyethylene pipe. The result is a water-tight joint whose inside and outside diameters are the same as those of the pipe. The following list highlights other characteristics of the Snap-Tite liner system.

• Improved Flow Characteristics
• Water-tight Joints
• Outstanding Chemical & Corrosion Resistance
• High Environment Stress Cracking Resistance
• Toughness & Ductility
• Flexibility with Light Weight
• Abrasion Endurance
• Fatigue Endurance
• Reliability
• UV Protection

Flow Characteristics

Snap-Tite has an extremely smooth inside surface and maintains its excellent flow properties throughout its service life due to its excellent chemical and abrasion resistance. Because of its smooth walls and non-wetting characteristics, a higher flow capacity and a reduced friction loss is possible. Snap-Tite typically has a Manning roughness coefficient of 0.009 and a Hazen Williams flow factor of 155. The charts on the following pages demonstrate how the Snap-Tite system gives you a more durable pipe with a smaller ID that carries as much, if not more fluid than the original pipe!
