Manufactured in strict compliance with ISO 2531 (international standard) and EN 545 (European standard), our centrifugally cast ductile iron pipes are designed for pressurized water transmission, including potable drinking‑water, raw water, irrigation and municipal water‑supply networks.
Spheroidal graphite microstructure delivers the perfect balance of cast‑iron rigidity and steel‑like toughness. Available in a comprehensive diameter range from DN80 up to DN2600, with standard laying lengths of 6 m. Multiple joint solutions, including push‑on flexible joints and restrained joints, suit both underground and above‑ground pipeline installation for municipal, infrastructure and international water‑engineering projects.
Size Range: DN80-DN1800
High mechanical performance: Minimum tensile strength 420 MPa, elongation ≥10 %. Outstanding impact‑resistance and deformation tolerance to survive backfill settlement and ground movement.
Reliable anti‑corrosion system: Standard internal cement mortar lining and external zinc‑plus‑bitumen coating; alternative lining options are available to extend service life in aggressive soil and water conditions.
Flexible joint design: Push‑on socket‑spigot joints permit angular deflection at connections, helping to absorb minor ground displacement without pipe fracture. Restrained joints are offered for anti‑pull‑out requirements.
Long service lifespan: Proven long‑term durability, low lifecycle cost for municipal water distribution infrastructure.
Full‑range dimension options: Multiple pressure classes (K7, K9, C25, C30, C40) to satisfy different internal working‑pressure and burial‑depth requirements.
Global standard compliance: Meets both ISO 2531 worldwide requirements and EN 545 European specification, suitable for international tender and export projects.
Smooth inner lining: Low hydraulic friction loss, optimizes flow capacity for water transmission pipelines.
Standard operating temperature: 0 °C‑50 °C for water medium; freezing inside pipeline should be prevented. Higher‑temperature service requires special gasket solution & technical validation.
