Viega Megapress Presses thick-walled steel: cold, secure and fast.

Some things last. Even more than 110 years later. At Viega, innovation and entrepreneurial vision are now more alive than ever before – these success factors date back to the company founders. Today, the Viega Group employs more than 3,500 staff worldwide. Viega is working to continue its long-term success at nine locations. While production is concentrated at its four main sites in Germany, the McPherson/USA group manufactures solutions specially designed for the North American market. And the Wuxi/China site focuses on production for the Asian market. The company specialises in...

Megapress – the system: Saves assembly time, labour costs without getting hot under the collar. Assembly: Quick, clean, secure and completely weld-free. SC-Contur: Megapress ensures that steel pipes are leak-proof. You will give this seal your approval. Heating and cooling systems: Megapress leaves black steel cold. But not the fitters of heating and cooling systems. Versatility: For everything under pressure. Even in industrial and special applications. Pressing tools: Lasting connections made in seconds.

Viega Megapress SAVES ASSEMBLY TIME, LABOUR COSTS AND LOTS OF WELDING. Whether thick-walled or thin, varnished or galvanized, coated or black – steel pipes are versatile, long-lasting and particularly robust. So it’s good that Viega is now presenting a real innovation with the new Megapress system, which now makes steel pipes economically interesting for heating, cooling and industrial plant engineering.

Viega Megapress is the press technology that can press even thick-walled steel pipes. The rounded connectors made from steel material 1.0308 with zinc-nickel coating guarantee the highest quality, robustness and, consequently, longevity. With the Viega Megapress system, steel pipes in accordance with DIN EN ISO 6708 and DIN EN 10220/10255, in the dimensions of ½" to 2", can be securely and reliably connected. The alternative without any alternative In comparison to conventional connection methods, Viega Megapress is clearly at an advantage. The cold press technology is simply quicker, safer...

Viega Megapress QUICK, CLeAN, SeCUre ANd COMPLeteLY WeLd-Free. Black steel pipes have always meant: Welding. With Viega Megapress, press technology has now become established in steel pipe installation, bringing a whole range of advantages with it.

Welding is a thing of the past Granted, welding steel pipes is not a bad connecting option. But the installation itself is anything but easy. A high demand on time, a permanent risk of fire and major physical stress make welding economically unattractive. Heavy gas bottles and welding equipment have to be moved – a real back-breaking job, especially if a pipe needs welding at several metres above eye-level (Fig. 2). And in inaccessible or angled locations, inconvenient mirror-imaged welding is normally the only technique able to make the connection. Finished up to 60% quicker On the other...

Viega Megapress with SC-Contur ENSURES THAT STEEL PIPES ARE LEAK-PROOF. You will give this seal your approval. The economic superiority of press connection technology is down to its rapid, simple assembly. But also in terms of security, Megapress – as is the case with all Viega press systems – is able to particularly shine thanks to the SC-Contur.

The Viega SC-Contur is an innovative safety feature, which leads to a guaranteed forced leakage in unpressed connections. In this way, inadvertently unpressed connections immediately become visible during a leakage test and can then be pressed. The Viega SC-Contur guarantees complete security – over the entire test range. Complex requirements, simple solution Of course, Viega Megapress is also equipped with the SC-Contur, but in a slightly modified form: While the forced leakage is normally produced through a small channel on the sealing element, it occurs through a tolerance optimisation...

Viega Megapress for heating and cooling systems LeAVeS tHICK-WALLed SteeL COLd. bUt NOt tHe FItterS OF HeAtING ANd COOLING SYSteMS. When installing heating and cooling systems, there is lots to pay attention to – irrespective of whether it is a completely new installation or extensive renovation work. Viega Megapress offers a series of advantages in both cases, which will warm the cockles of any fitter’s heart.

Extremely practical in practice The advantages of Megapress quickly become clear in practice. In one specific case, a complex of three buildings with a total of 55 residential units was completed. Figure 1 shows the installation of two buffer reservoirs of an air-water heat pump, which uses Viega Megapress. About 500 connections of the new press system were fitted throughout the entire building project. Megapress satisfied the demands of the municipal developer to withstand both a certain time pressure and cost pressure. A task, for which Megapress is a quick and economical solution in...

Viega Megapress – versatile FOR EVERYTHING THAT’S PRESSURISED. EVEN IN INDUSTRIAL AND SPECIAL APPLICATIONS. When it comes to industrial applications, installations frequently have to be fitted in particularly high and inaccessible locations. When welding, you are faced with a real challenge here with lots of tools and heavy equipment. Such installations are physically strenuous, particularly tedious and uneconomical. Viega Megapress is the better alternative here. Because cold press technology can completely show off its advantages when it comes to difficult installations. It is not only...

Sprinklers and fire extinguishers Sprinkler systems made of thick-walled steel pipe are mandatory in buildings with high risk categories such as industrial and commercial plants due to their robustness, stability and longevity, legislative authorities even demand their use. Ultimately, they must withstand the increased everyday external strains as well as great heat in the case of a fire. 1 Viega Megapress is ideal for creating and expanding such sprinkler systems (Fig. 3). The Vds and FM certification will probably have been awarded before the market launch.
