HS Umformtechnik GmbH produces for the plastics, food and chemical industries the aluminum pipe coupling DVK 6 for suction conveying in a light design and the heavy-duty DVK-HD® high pressure for pressure conveying. These couplings can be used anywhere where pipes, pipe bends and branch pieces have to be connected gas-tight. The pipe couplings DVK 6 and DVK-HD® high pressure stand for quick and safe assembly with an ideal price-performance ratio. Since no welding work is necessary - easy to disassemble - pipe couplings and pipes can be reused. The aluminum pipe coupling type DVK 6 is available in lengths of 100 mm (vacuum) and 150 mm (pressure) or longer. All common diameters from 33.7 to 110.0 mm are currently available. The coupling was tested by TÜV according to HS specifications. The aluminum pipe coupling type DVK-HD® high pressure is available in lengths of 100 mm, 150 mm and 200 mm or longer. All common diameters from 60.3 to 206.0 mm are available. The coupling was tested by TÜV according to hs specifications and is patented (German Patent Office Munich / Patent No. 10 2008 031 485)
