Hydraulic and plumbing specialists using copper piping the world over have always relied on soldering for all types of installations. But for more than 20 years, German plumbing engineering company Viega has revolutionised pipe systems press connection technology as a faster and safer alternative.

Established almost 120 years ago in Germany, Viega is leading the way internationally when it comes to press connection technology. In the mid-1990s and in the year 2000, it revolutionised the market twice in quick succession: first with the introduction of the Propress system, then with the Smart Connect-Feature. And the company hasn’t stopped there.

Now used in millions of applications around the world, not only in sanitation, heating and gas applications, but also in industrial facilities such as compressed air, cooling waters and process media, press connection technology is recognised as the modern-day alternative to traditional soldering here in Australia.

Less time, less money, less risk and less hassle. And here’s why.

Quick and cost-effective

With Viega’s Propress technology, work can be completed up to 75 per cent more quickly than using conventional soldering procedures.

Ultimately, only three steps are required: cut the pipe, press and finish. Laborious preparation and finishing work such as drying pipes and removing traces of fire and solder is no longer required.

Safety first

As a cold applied solution, press fitting connection offers a safer and cleaner alternative to hot works and allows a secure connection even where space around the pipe is limited.


Viega’s double pressing technique – one before the seam and one after – guarantees long-lasting stability in the pipe system, and the Smart Connect-Feature technology included in products across the Viega range also ensures maximum leak detection. Unpressed connections are guaranteed to be noticed when filling the installation.


Unlike soldering, there’s no oxygen or gas cylinder, no burner and no soldering accessories to transport and maintain.

Viega Pressguns are light, quick, safe and require minimal maintenance.


And thanks to the flexible articulated press jaws, they can easily be used in even hard-to-reach installations without causing a fire hazard.

Extreme conditions call for robust piping systems

On the rocky Antarctic plateau adjacent to the Larsemann Hills, at temperatures down to minus 40°C, India has been operating a science research station since 2012. Named “Bharati”, after the Hindu Goddess of Wisdom and Knowledge, it serves as headquarters for climate change and oceanographic research.

To enable Bharati’s researchers to continue their vital work in extreme conditions during the Antarctic winter, it required especially robust drinking water and heating solutions.

Drinking water hygiene is particularly vital at the remote location. Contamination by Legionella or similar harmful microbes would be disastrous not only for the researchers – the very future of the mission would be placed at risk.

That is why the planners chose Viega’s Sanpress Inox system with pipes made of premium quality EN1.4521 stainless steel. Viega Easytop circulation regulating valves ensure that the hot water is kept at a constant 60°C. The facility’s thermal disinfection system provides further protection against Legionella, while Easytop extraction valves enable regular monitoring of drinking water quality.

Kerosene is used to generate heat and power, because it remains liquid down to minus 54°C. So to aerate the tank, Indian engineers installed the Viega Sanpress Inox G piping system because of its permanent resistance to the media being pumped. Sanpress Inox G is usually used for gas and heating oil pipes and was launched in Australia in 2013.
