Pipe Transition Connector

The Pipe Transition Connector joins pipes that have different diameters or different materials. In real projects, you often need to connect a DN100 ductile iron pipe to a DN80 steel pipe. Or you need to connect a PE pipe to a galvanized steel pipe. Our connector has different sizes on each end. One end fits one pipe. The other end fits the other pipe. This gives you a seamless transition.
 

Bridges Different Pipe Sizes and Materials

 

 

The Pipe Transition Connector joins pipes that have different diameters or different materials. In real projects, you often need to connect a DN100 ductile iron pipe to a DN80 steel pipe. Or you need to connect a PE pipe to a galvanized steel pipe. Our connector has different sizes on each end. One end fits one pipe. The other end fits the other pipe. This gives you a seamless transition.

 

Each end has an independent seal. The seal ring and internal bore are sized for the specific pipe on that side. A limit stop in the middle keeps the two pipes separate. This prevents galvanic corrosion between different metals. The connector solves three problems at once: different diameters, different materials, and mixed conditions. Installation needs no welding and no flanges. The process is much simpler.

 

We have our own R&D team with many patents. We are good at making non-standard and custom connectors. Give us the pipe material and diameter for each end. We will make a connector that fits exactly. Delivery time is typically 15 to 20 days. We have served many water utilities, water groups, and municipal engineering companies. We have deep experience in transition connections. Our products are tested by the Shanghai Institute of Quality Inspection. They pass housing strength and seal performance standards.

Custom Made for Your Exact Pipes

 

 

A town water plant was upgrading old pipes. They needed to connect a DN150 cast iron pipe to a new DN200 PE pipe. The diameters and materials were different. The plant asked us to custom make a Pipe Transition Connector. One side fit the cast iron OD. The other side fit the PE OD. The installation was a success on the first pressure test. The plant used our connectors for many similar connections in later projects.

 

We offer a 10-year warranty. Each connector comes with detailed installation instructions and a dimension confirmation sheet. If you send us a pipe sample or give us exact OD measurements, we will ensure a precise fit.
