PE4710 Pipe: The Advanced Solution for Demanding Applications
When specifying materials for critical infrastructure projects involving drainage, sewer systems, or water mains, the choice of pipe is paramount. PE4710 pipe represents a significant leap forward in polyethylene pressure pipe technology, offering unparalleled performance and longevity. Its superior characteristics make it an excellent choice for applications that traditionally use HDPE Culvert Pipe or HDPE Corrugated Pipe, providing higher pressure ratings and enhanced resistance to slow crack growth. For systems requiring precise dimensional control, such as those utilizing HDPE Dr11, PE4710 offers a robust alternative with improved hydrostatic design basis. Furthermore, its compatibility with standard fusion techniques ensures secure and leak-free connections with various HDPE Coupling systems, streamlining installation and ensuring long-term system integrity.
Unmatched Performance Characteristics of PE4710 Pipe
The PE4710 pipe is engineered from a high-performance polyethylene material that meets the stringent requirements of ASTM D3350. This compound is classified as PE4710, indicating its elevated performance level compared to standard PE materials like PE3608 or PE4710. The key to its performance lies in its enhanced resin properties, which provide a higher Hydrostatic Design Basis (HDB) of 1600 psi at 73.4°F (23°C). This allows for thinner pipe walls at the same pressure rating compared to older generations of HDPE, or higher pressure capacity for the same outside diameter. The material's exceptional resistance to rapid crack propagation (RCP) and slow crack growth (SCG) ensures a extended service life, often exceeding 100 years under normal operating conditions. Its toughness and durability make it highly resistant to impact damage during handling and installation, as well as to chemical attack from a wide range of soils and effluents. The flexibility of PE4710 pipe allows it to withstand ground movement and settlement, making it ideal for use in seismic zones or areas with unstable soil conditions.
