The core of the technology is the automated welding process, where the tank is simultaneously welded on the inside and the outside. Similar to the Lipp double fold technology the material will be pre formed by Lipp special forming machines and reinforcement ribs are applied for additional stability. By doing so, the wall thickness can be reduced which will have an economic effect on the overall material costs, without compromising structural stability. The process also enables the installation of roofs and other accessories at ground level, which reduces the risk of working at heights. The main application for the new Lipp welding technology is the drinking water sector. However, there is lots of market potential in the food and beverage industry, chemicals and pharmaceuticals as well as other industries. The black steel welding technology enables the installation of bulk silos with huge diameters and volumes, which is a significant improvement compared to today.

Lipp offers a range of metallic materials suitable for use with a wide variety of media, from pure water to problematic and aggressive substances. Those materials range from galvanised/black steel through the combination material VERINOX to high alloy stainless steels. VERINOX stainless steel is a patented, award winning combination material that offers the properties of high quality stainless steels, e.g. 1.4301, 1.4571 or 1.4539, at the cost of galvanised steel and has been in use for more than 20 years. The highest quality and longevity of materials are our top priorities. LIPP MATERIALS AT A GLANCE Stainless steels VERINOX stainless steel Galvanised steels Black steels

Stainless steel is expensive. Verinox offers the same level of quality as the conventional material used for the construction of tanks and containers while using less stainless steel. With Verinox – the duplex material developed by Lipp – a sheet of stainless steel is joined to a sheet of galvanised steel by means of a separation layer. Three components form the basis for this material that is ideal for tank and container construction not only does it have outstanding physical properties but it also uses a reduced quantity of expensive stainless steel, resulting in lower costs. With this invention, Lipp has successfully retained the economic benefit of the LIPP Double Seam System while improving the material savings made. VERINOX ENABLES STAINLESS STEEL TO BE USED INSIDE TANKS – ESPECIALLY WITH MEDIA THAT REQUIRE SUFFICIENT RESISTANCE No open joints due to the folded design Doubly lined in stainless steel with a smooth continuous finish

Special features of the Lipp welding technology are the automated on site construction of above the ground cylindrical tanks made of various grades of duplex steel, stainless steel and black steel. Moreover, the technology also incorporates the post treatment of the weld and a visualized welding monitoring and the technical documentation of the process. Due to the flexible and mobile concept of the equipment, the installation can either be done on greenfield construction sites but also inside buildings or in places with limited access and working space.
