What if a standard fusion machine doesn’t fit your application?

Not every pipeline project can be solved with an off-the-shelf machine.

At RIYANG, our capabilities go beyond standard butt fusion equipment. Through our ETO (Engineer-to-Order) service, we design and manufacture purpose-built fusion machines around specific pipes, fittings, production processes, and project requirements.

Some of our specialized solutions include:

🔥 PipeShell™ Serie
Butt fusion machines developed for **district heating pipelines**, including specialized pipe structures and fabrication requirements.

🌳 PipeTree™ Series
Dedicated **manifold pipe welding machines** for efficient and repeatable fabrication of complex manifold assemblies.

🔵 VaFusion™ Series
Purpose-built welding machines for the fabrication of HDPE ball valves.

From a special clamping requirement to an entirely new machine configuration, the process starts with one question:

What do you need to weld?

Tell us the application, pipe dimensions, fitting geometry and production requirements — our engineering team can work from there.

Don’t adapt your project to the machine. Let’s engineer the machine around your project.

Low Pressure or High Pressure? Which Standard Do You Trust? 🤔
When it comes to HDPE pipe butt fusion, one question continues to spark discussion among contractors and engineers:
👉 Do you prefer Low Pressure or High Pressure welding?
Both methods can produce strong, reliable joints—but they follow different welding philosophies, operating procedures, and project requirements.
The right choice often depends on:
✔ Project specifications
✔ Applicable standards
✔ Pipe size and material
✔ Long-term performance expectations
At RIYANG, we've put together a practical guide comparing both approaches to help professionals make informed decisions.

💬 We'd love to hear from you:

One world. One final. One shared future. ⚽🌍

Spain and Argentina are ready for football’s biggest match.

For 90 minutes, there will be two sides, two colors and one champion. But beyond the competition, the World Cup reminds us of something greater:

Different nations can meet on the same field.
Different cultures can share the same passion.
And people from every background can be connected by a common purpose.

At RIYANG, we see the same spirit in the infrastructure projects supported by our butt fusion machines around the world.

Pipelines may cross cities, deserts, mountains and national borders—but their purpose is universal: delivering water, energy and essential services to communities.

Our machines are built for demanding projects.
But the future they help build belongs to everyone.

Beyond borders. Beyond differences. Connected by one shared future.

May the best team win—and may football continue to bring the world closer together.

Built for the big match. Engineered for a connected world.
