The clamp design allows for quick and easy installation without specialized tools, ensuring a secure connection in various pipeline systems.
Our ductile iron flange adapter with clamp is designed to connect plain-end pipes to flanged valves, pumps, meters, fittings and pipeline equipment quickly and securely. With a strong ductile iron body, EPDM rubber gasket and clamp-style mechanical sealing structure, it provides a dependable solution for water supply, sewage, irrigation, industrial pipeline and municipal pipeline projects.
Compared with traditional welded or threaded connections, this clamped flange adaptor helps contractors reduce installation time, simplify site adjustment and improve sealing performance. It is suitable for ductile iron pipe, steel pipe, cast iron pipe, PVC pipe and other compatible pipeline materials, making it a practical choice for both new pipeline construction and maintenance replacement projects.
The clamp design allows the flange adapter to be installed directly on the pipe end without welding, threading or grooving. Installers only need to position the adapter, align the flange holes, tighten the bolts and complete the connection. This makes it especially suitable for on-site installation where cutting, welding or special tools are inconvenient.
The adapter body is made from high-strength ductile iron, offering excellent mechanical strength, impact resistance and long service life. It is suitable for underground pipelines, water distribution networks, pumping stations and other demanding pipeline environments.
The built-in rubber gasket creates a tight seal around the pipe surface. When the clamp bolts are tightened, the gasket is compressed evenly to help prevent leakage under working pressure. EPDM sealing rubber is commonly selected for clean water, neutral liquids and sewage applications.
This ductile iron flange adapter with clamp can be used with different pipe materials depending on project requirements, including:
| Compatible Pipe Type | Typical Application |
|---|---|
| Ductile iron pipe | Municipal water supply, fire water systems |
| Steel pipe | Industrial pipeline and pump station connection |
| Cast iron pipe | Pipeline repair and replacement |
| PVC pipe | Water distribution and irrigation systems |
| Other compatible pipes | Project-based connection solutions |
The adapter can be supplied with epoxy coating for improved corrosion resistance. This helps extend service life in buried pipelines, humid environments and water treatment systems.

Easy Site Adjustment
The clamp-style structure allows more convenient positioning and alignment during installation.
Secure Pipe-to-Flange Connection
Designed to connect plain-end pipe to flanged valves, fittings, meters and equipment.
Wide Material Compatibility
Suitable for ductile iron pipe, steel pipe, cast iron pipe, PVC pipe and other compatible pipe systems.
Stable Sealing Under Pressure
Rubber gasket compression helps ensure leak-resistant performance.
Project-Based Customization
Size, coating, flange standard, gasket material and bolt material can be customized.
Suitable for Water and Sewage Systems
A practical choice for municipal, industrial and utility pipeline applications.
The adapter is installed over the plain end of the pipe. As the bolts are tightened, the clamp ring compresses the gasket around the pipe surface. The flanged end is then bolted to a valve, fitting, pump, meter or other flanged component. This creates a strong mechanical connection and a reliable sealing interface without requiring welding or pipe end machining.
This structure makes the ductile iron flange adapter with clamp especially useful for projects that require fast installation, future maintenance access or flexible connection between different pipeline components.
A ductile iron flange adapter with clamp is used to connect a plain-end pipe to a flanged valve, fitting, pump, meter or pipeline equipment. It is commonly used in water supply, sewage, irrigation and industrial pipeline systems.
Yes, depending on the pipe outside diameter and project requirements, the flange adapter can be used with PVC pipe, ductile iron pipe, steel pipe, cast iron pipe and other compatible pipes.
No. The clamp-style flange adapter is designed for mechanical installation. It does not require welding, threading or grooving, which helps reduce installation time on site.
Common pressure ratings include PN10, PN16 and PN25. The correct pressure rating should be selected according to pipeline design pressure, flange standard and working conditions.
EPDM is commonly used for water and sewage applications. NBR or other gasket materials can be supplied according to the medium and project requirements.
Yes. We can supply flange adapters according to EN1092, ISO, ANSI, AWWA or project-specific flange drilling requirements.
Yes. Fusion bonded epoxy coating or epoxy powder coating can be supplied to improve corrosion resistance and extend service life.
You need to confirm the pipe outside diameter, nominal size, pressure rating, flange standard, pipe material and application medium. Providing project drawings or pipeline specifications helps ensure accurate selection.
