HS Umformtechnik GmbH is a medium-sized family-run business which has grown continuously since it was founded in 1997. We keep the promises we make. At our company headquarters in Grünsfeld-Paimar, Germany, our 50 motivated employees produce high-quality stainless steel pipe bends, pipe couplings, coupling stations, suction tubes, branch and transition pieces as well as customized parts using cutting edge machinery at our production site which covers 12, 000 square metres. In doing so, we not only engage in effective problem solving and scout out top quality products on behalf of our customers, we also provide a good price/performance ratio. Beyond this, we always have all common dimensions of stainless steel bent pipes and pipe couplings as well as stainless steel pipes in stock in our around 5000 square metres of production and storage space. Besides consistent high quality, this also means short delivery times for our customers.

Our speciality are thin-walled pipe-bends with large bending radius, especially for pneumatic conveying systems. The pipe-bends are cold-bent without any pleats on CNC-mandrel machines. Our quality management generally guarantees: welded seam smoothed or shaved (DIN 11 850 resp. DIN 17 457) absolutely wrinkle-free, no start-up bulges no scratching or scoring extremely low ovality visually aesthetic surface leg extension each side deburred sawing edges

DVK-HD® high pressure pipe couplings are perfect for a quick and well-priced mounting for pressure conveyors. They have the following characteristics: for outer pipe diameter from 60.3 to 206.0 mm length: 100, 150, 200 mm or longer metal casing made of aluminium AlMgSi 0.5 F22 massive aluminium clamps (double secured) screws M12 with massive threaded bars pressure-resistant up to maximum of 12 bar (see table) vacuum-resistant up to maximum of 0.8 bar (see table) circular version, therefore very easy to mount white EPDM gasket or nitrile gasket, temperature-resistant and food-safe optionally available with silicone gasket (-60°C to +200°C) Mounting these pipe couplings is safe and hazard-free because no welding works are necessary. They also can easily be dismantled – connecting pieces and pipes can be reused.

DVK-HD® quick closure pipe couplings are ideal for a quick and safe mounting in pressure conveyors. The coupling is closed with two clamping levers, therefore a quick opening and closing of pipe connections is possible. The clamping lever can be locked in any desired position by a simple upward pull.
