It can be adapted to certain ranges of steel pipes, PE pipes, ductile iron pipes, etc.
The connection is achieved through flange and bolt fastening, without the need for welding, and the installation is quick.
It features a locking lever/ bolt structure, which can withstand certain internal pressure and thrust to prevent the pipeline from being pulled out.
It is resistant to aging, water, weak acids and alkalis; it can be customized with food-grade rubber as per requirements.
It is applicable to scenarios such as municipal water supply and drainage, sewage treatment, building fire protection, HVAC, agricultural irrigation, etc.
Ductile iron universal flange adaptor PN10 PN16, fits steel, DI, PE, PVC pipes. No welding required, fast installation, reliable sealing with angular‑axial compensation. Ideal for water‑sewage pipeline renovation, factory supply, custom sizes available.
This ductile iron flange adaptor is designed for fast, secure connection between plain-end pipes and flanged equipment such as valves, pumps and meters. The corrosion-resistant epoxy coating protects against aggressive water and soil conditions, while the wide-range sealing system accommodates steel, PE, PVC and ductile iron pipes within the same nominal size. No welding or special tools are required — simply tighten the high-tensile bolts to activate the rubber gasket and create a pressure-tight seal. Available with EPDM or NBR gaskets for water, wastewater and industrial applications.
