If your project requires a pipe system that fits perfectly, performs reliably, and is tailored to your exact specifications, you’re going to need more than standard lengths and off-the-shelf fittings. You’ll need custom pipe fabrication—a process that allows your piping system to be purpose-built for your application, whatever it may be.
At UPG Pipe Systems, we specialise in fabricating polyethylene (PE) and high-density polyethylene (HDPE) piping systems. Our fabrication service supports industries across New Zealand, from civil and infrastructure to irrigation, industrial process systems, and beyond.
So, what exactly is pipe fabrication—and how can it improve the way your project comes together?
Defining Pipe Fabrication
Pipe fabrication is the process of preparing and assembling pipe components into custom-built configurations—ready for installation on-site.
Pipe fabrication typically involves:
- Cutting the pipe to specific lengths
- Joining the pipe and fittings using advanced welding techniques
- Assembling prefabricated spools, manifolds, junctions, and other custom components
- Testing the quality and integrity of joints and assemblies
At UPG, our fabrication services are focused on delivering tailored polyethylene pipe systems that are engineered for efficiency, durability, and ease of installation.
What Makes UPG Pipe Fabrication Different?
Our fabrication capability is backed by both technical expertise and a flexible workshop. At UPG, we say our fabrication is limited only by your imagination. We can produce an enormous range of custom fittings and configurations to match your project requirements—including fabricated bends, tees, reducers, stub flanges, junctions, and complex manifold systems.
We also offer:
- Design support to help optimise your system layout
- Guidance on material selection for performance and cost-efficiency
- Expertise from sales engineers who understand how different applications demand different solutions
We work closely with contractors, engineers, and project managers to ensure what we fabricate works for your site, timeline, and budget.
Our Process: From Concept to Delivery
Interested in understanding our process? Here’s how our pipe fabrication service works:
1. Understanding Your Needs
We begin by working with you to understand your project’s scope, challenges, and requirements. Whether you have detailed technical drawings or just a rough concept, we can help shape it into a workable solution.
2. Custom Design and Engineering
Our team will assist in designing a system that maximises performance and minimises cost. This includes selecting the right type of PE or HDPE material and identifying potential efficiencies in layout or connections.
3. Fabrication in Our Warehouse
Using industry-leading butt welding and electrofusion technology, we manufacture and assemble components to your exact specifications. Our team has years of experience and a reputation for high-quality workmanship.
4. Testing and Quality Assurance
We stand behind every weld. All fabricated components undergo stringent quality checks to ensure they’re ready for long-term use in demanding conditions.
5. Delivery and On-Site Support
We deliver prefabricated systems ready to be installed. If needed, we also offer on-site welding, operator training, weld testing, and welding equipment for hire—so you’re supported every step of the way.
Who We Work With
Our pipe fabrication solutions are used across a broad range of sectors:
- Civil and Infrastructure – Water mains, rising mains, sewer systems, and stormwater networks
- Irrigation and Agriculture – Manifolds, take-off systems, and large-scale water distribution networks
- Industrial and Process Engineering – Compressed air, chemical handling, and plant water systems
- HVAC and Mechanical Services – Piping systems for heating, cooling, and ventilation
- Plumbing and Drainage – Residential and commercial piping installations requiring custom configurations
Why Use Fabricated PE Pipe Systems?
Choosing fabricated polyethylene pipe systems offers a number of key benefits:
- Fast Installation – Custom spools and manifolds arrive ready to install, saving time on site
- Accurate Fit – Fabricated systems eliminate guesswork and reduce the need for on-site adjustments
- Superior Durability – HDPE and PE offer excellent chemical resistance, flexibility, and service life
- Cost-Efficient Builds – Reduce material wastage and streamline labour by fabricating off-site
Whether your project requires a single fabricated bend or a fully customised, pre-assembled piping system, UPG has the capability to deliver. We’re more than just a pipe supplier—we are your fabrication partner, working with you to deliver smart, reliable, and efficient solutions using the best polyethylene materials on the market.
