FLEXIBLE, SAFE AND PROVEN THE WORLD OVER – THE LIPP DOUBLE SEAM SYSTEM Conventional systems are often unsuitable for the optimum, safe storage of solid or liquid substances and their use can result in premature corrosion, leaks and problems with safety. Flexibility is another important factor. Tanks must be flexible in terms of size and substrate and optimally adaptable to the local conditions. THE LIPP DOUBLE SEAM SYSTEM HAS PROVEN ITSELF TIME AND TIME AGAIN ALL OVER THE WORLD FOR MORE THAN 45 YEARS MULTI AWARDED. The principle of the LIPP Double Seam System is as follows the edges of steel strips are folded over together twice, connecting them together in such a way that even aggressive liquids inside the tank cannot find any surfaces to attack. The result corrosion is prevented and maximum leak tightness is achieved.

LIPP® Liquid Storage Tanks are fabricated with best material, as this is the most important quality factor. Municipal/industrial waste water and sludge or certain processing, intermediate and end products from the chemical, pharmaceutical and food processing industries set high requirements regarding the tank material, for example. LIPP offers a variety of materials, ranging from galvanised steel through the combination material Verinox to highalloy stainless steels. Variants waste water tanks sewage sludge tanks process water tanks storage tanks firefighting water tanks Mixing and compensation tanks buffer tanks stockable sludge tanks rainwater reservoirs Filtrate water tanks activation tanks Percolating filter tanks Landfill leachate tanks & Special tanks on request

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.

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® Welded Tanks offer the ideal storage solution for a wide variety of media. Tanks are produced by means of an automated welding process specially developed by LIPP® and can be constructed individually in diameter in volumes of 50 to 10,000 m³ according to the application. LIPP® offers a corresponding selection of metallic materials suitable for use with storage media ranging from drinking water and foodstuffs to ethanol or oil. These materials range from a variety of different steel grades to highalloy stainless steels. The automated process meets the highest quality standards. LIPP® Welded Storage Tanks can be produced within a short time, either on site in the open air or inside a building.

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

TECHNOLOGICAL INNOVATION OPENING UP NEW MARKETS The new automated Lipp welding process will again shake up tank construction market just as the well established Lipp double fold system did decades ago. It is a perfect combination of the long experience in metal forming and state of the art welding technology. KEY BENEFITS OF THE LIPP WELDING TECHNOLOGY Automated welding proces, on site Visual weld monitoring and technical documentation Reinforcement ribs for enhanced structural stability and reduced material costs High quality and repeatability Fast installation Choice of different material grades and types CERTIFICATES SPECIFICATIONS OF THE LIPP WELDING TECHNOLOGY BLACK STEEL SPECIFICATIONS OF THE LIPP WELDING TECHNOLOGY STAINLESS STEEL Beside black steel, various grades of stainless steel and duplex steel can be auto welded. In addition to the new potential markets and applications, the Lipp automated welding technology will increase the competitiveness

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

The LIPP® Large Thermal Storage Tank is a customized solution to effectively store excessive heat from biogas plants, biomass heating plants, solar plants or other heat sources. The carbon steel tanks are fabricated on site with the patented automated LIPP® Welding Technology. The horizontal welding process enables the infinitely variable production of tanks up to 6,000 m³ volume with horizontal welding only. The largevolume, above ground storage tanks are fitted with all necessary safety and operation equipment. Additional, individual components according to client’s specification can be considered. The roof and wall insulation is individually adapted to local conditions. The LIPP® Thermal Storage Tanks operate at atmospheric pressure, at a temperature of up to 95° C and are suitable for use with heating water. Speciality No additional nitrogen system necessary.
