Overview:
Our ductile iron adaptor fittings are specially engineered to create reliable transition joints between ductile‑iron pipeline systems and PVC plastic pipes. Manufactured in compliance with ISO 2531 and EN 545, this product range includes flange adaptors, universal couplings, gibault repair couplings and service saddles, covering sizes from DN50 up to DN600.
Featuring high‑strength GGG50 ductile iron bodies, EPDM rubber gaskets and optional restraint locking rings, these transition fittings are widely deployed for municipal water‑supply network renovation, new hybrid pipeline construction, irrigation projects and on‑site pipe repair. The flexible joint design compensates for minor pipe misalignment and ground settlement, delivering leak‑free service for buried water pipelines. Fusion‑bonded epoxy coating provides excellent underground anti‑corrosion performance for long‑term service life.
Key Features:
Inter‑material Transition Solution: Purpose‑built for connecting DI pipelines with PVC‑U pipes; ideal for mixed‑material water supply networks and pipeline rehabilitation projects.
International Standard Compliance: Produced according to ISO 2531 and EN 545; available for PN10, PN16 and PN25 working pressure ratings, suitable for international municipal tender projects.
Secure Sealing & Restrained Connection: High‑quality EPDM rubber gaskets guarantee reliable water‑tight sealing. Optional brass locking rings provide axial restraint to prevent pipe pull‑out under working pressure.
Flexible Misalignment Compensation: Joints allow limited angular and axial deflection, absorbing ground movement and pipe displacement caused by soil settlement.
Robust Anti‑Corrosion Protection: Fusion‑bonded blue epoxy coating (RAL 5017) on ductile iron body; drinking‑water safe coating suitable for potable water transmission.
Wide Size Range & Versatile Types: Full portfolio including flange adaptors, universal repair couplings, gibault joints and service saddles, covering DN50‑DN600 to satisfy different site installation requirements.
Simplified On‑site Installation: No special pipe‑end machining required; fast bolt‑tightening assembly reduces overall construction time on site.
