Difference Between Green and White PPR Pipe Welding Machines

Difference Between Green and White PPR Pipe Welding Machines

Last Updated: October 15, 2025

Pipe welding machines — commonly known as PPR welding tools — are essential devices for connecting polypropylene pipes (PPR) in both residential and industrial plumbing systems.
Although green and white pipe welding machines look similar, they differ in build quality, heat capacity, application range, and price, making the right selection crucial for durability and performance.
This article dives deep into the differences between green and white pipe welding machines, exploring their strengths, weaknesses, and expert buying tips.

What Is a PPR Pipe Welding Machine?

A PPR Pipe Welding Machine (commonly called a pipe fusion tool) is used to heat and fuse polypropylene pipes and fittings.
By heating both pipe ends to their melting point, it allows them to fuse together, forming a leak-proof, pressure-resistant joint.

There are two primary categories:

• Green PPR Welding Machines
• White PPR Welding Machines

-Each is designed for a specific pipe type and temperature requirement.

 Green PPR Welding Machine — Features and Applications

The Green PPR welding machine is a professional-grade tool specifically engineered for green polypropylene pipes (PPR Green).
It operates at up to 280°C, ideal for high-pressure and high-temperature systems such as heating, cooling, and industrial water pipelines.

Advantages

1. Superior Performance for Green Pipes,Designed for PPR Green pipes with a higher melting point (up to 280°C). Perfect for heating systems and pressurized networks.

2. Advanced Teflon-Coated Nozzles ,Multi-layer Teflon coating (0.5mm standard) prevents pipe sticking and lasts up to 5,000 welds, about 30% longer than non-Teflon models.

3. Ultra-Strong Joints,Tested under hydrostatic pressure up to 20 bar, with less than 0.5% failure rate — ideal for industrial or commercial use.

4. Durable Construction,Reinforced aluminum alloy body resists corrosion and heat, performing reliably in harsh construction environments.

Disadvantages

1. Higher Price — Typically 20–30% more expensive due to stronger heating elements and Teflon coatings (up to 2500W).
2. Limited Large-Diameter Compatibility — For pipes above 110mm, an industrial model (3000W+) is required.
3. Specialized Maintenance — Requires regular Teflon cleaning and annual thermostat calibration to ensure temperature accuracy.

 White PPR Welding Machine — Features and Applications

The White PPR welding machine is commonly used for standard white polypropylene pipes found in home plumbing and low
pressure systems.
It generally heats up to 260°C and does not include a Teflon coating on the nozzles.

: Advantages

1. Affordable Price ; Around 30% cheaper than green models, making it ideal for home projects like cold/hot water supply lines up to 63mm.
2. User-Friendly Design; Simple structure with minimal moving parts; easy to clean and operate — suitable for DIY users or beginners.
3. Efficient for Light Work; With 800–1500W power output, it achieves a 98% welding success rate for domestic projects.
4. Lightweight and Portable ; Weighing under 4 kg, it’s easy to carry and perfect for working in tight spaces.

 Disadvantages

1. Not Compatible with Green PPR Pipes — Lower heat capacity (260°C) may lead to weak welds on higher-density pipes.
2. No Teflon Coating — Bare metal nozzles can cause sticking; cleaning is required after every 50–70 welds.
3. Not for Industrial Use — Performance drops when used for pipes over 63mm or long consecutive welds.

 Conclusion

• Both green and white PPR welding machines serve important roles in the plumbing industry.
• Choose a green PPR welder if your work involves high-pressure, hot-water, or industrial systems, where durability and precision matter.
• Opt for a white PPR welder for home repairs or small-scale projects, where ease of use and affordability are priorities.
• Selecting the right machine ensures strong joints, zero leakage, and long-term performance — the foundation of any reliable plumbing system.
