Medium-Density Polyethylene (MDPE) pipes combine flexibility, toughness, and reliable performance for pressure-rated underground systems. The material provides excellent resistance to cracking, chemical exposure, and ground movement, making it ideal for gas and water distribution networks. MDPE’s moderate density allows easy installation and fusion joining while maintaining long-term strength. It is widely used in utility infrastructure, municipal service lines, and industrial systems that demand durability and corrosion resistance.
