Welding technology - Import export

The future is lightweight – with Flexweld®. Flexweld®, the unique joining process, offers countless benefits, with one of the biggest advantages being the considerable weight ­reduction in the age of lightweight construction. Moreover, no additional machinery is required to incorporate it into an existing car body assembly line. significant weight saving, which provides long-term reduction in CO2 emissions joins lightweight materials to high-strength metals can be incorporated into existing assembly lines since it is possible to use the same production and welding equipment no additional qualification for workers needed complete system including full feeder and processing technology mixed production possible by adapting the spot weld gun software

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 welded tanks are erected using the LIPP Welding Technology, a unique method of construction enabled by a custom automated rig designed and manufactured by LIPP. This procedure can claim a number of advantages over other traditional welding methods. Firstly, the unique steel profile increases stability and so reduces material costs at the same time. Secondly, the automated endless tape process continually welds layers below in a rotational cycle and reduces the number of on site workers. LIPP Welding Technology enables welding both black steel and stainless steel of different grades, allowing numerous applications. LIPP aims to increase construction efficiency through the implementation of unique techniques and technology, ultimately benefiting customers via a cost effective system. The key facets for the construction of a LIPP storage system are automation, continuously variable tank dimensions, reduced space requirements for onsite construction and increased worker safety.

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.

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.

SOLUTION TO EFFECTIVELY STORE EXCESSIVE HEAT FROM BIOGAS PLANTS – FROM 2,000 TO 6,000 M³ The LIPP® 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 MAW welding process enables the infinitely variable production of tanks up to 6,000 m³ volume with horizontal welding only. The large volume, 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. No additional nitrogen system necessary.

GUARANTEED OPTIMUM STORAGE FOR A WIDE VARIETY OF MATERIALS The storage of bulk materials needs to be not only cost effective but also safe, and systems should be easy to integrate in production processes. LIPP Double Seam technology and welded LIPP tanks have proven to be particularly suitable for bulk storage applications in industry and agriculture. LIPP silos provide a high level of stability and total leak tightness and protect bulk materials from moisture. The smooth internal walls of the silos are a benefit that pays dividends when storing special media. All kinds of bulk materials Grain Soya Silage fodder Woodchips Pellets Clinker brick Cement SILOS FOR STORING GRAIN AND OTHER FOODSTUFFS Grain, soya and other foodstuffs are precious commodities and a major asset in agriculture and they need to be stored particularly carefully. With the tried and tested Lipp Double Seam System, Lipp silos offer major benefits in terms of design and leak tightness.
