DuroMaxx^® Joining Technology and Joint Types

DuroMaxx's steel reinforced bell and spigot achieves a level of watertight (WT) joint performance that sets it apart from conventional pipe products. The DuroMaxx joint is designed to meet, exceed and maintain the highest standards of performance when tested in accordance with ASTM D3212. Tested to 15 psi, DuroMaxx joints greatly exceed ASTM's 10.8 psi requirement. For lower performance applications, 2 psi silt tight (ST) or soil tight joints are available. Fusion welded joints are also an option.
