DUCoaT – pipes and ducts with Halar-interior-coating are used in exhaust air facilities where highly aggressive exhaust process air from the machines is released into the atmosphere through the scrubber system. Available standards for pipes, fittings, connecting systems and special components, such as multi-leaf dampers and silencers, are compiled in our planning folder. Upon request we are happy to inspect rectangular systems and special parts, such as scrubbers, tanks and customer drawings to verify that they conform to FM regulations and stability.

Pressure piping and suction piping for filter systems. The bend has a streamlined design with a large radius for a better transportation of the dust. The centrifugal fan creates high overpressures and low-pressures that must be accommodated by the piping system without excessive deformation. Flange connections are required for the assembly and are to be provided by the customer. These allow for an easy exchange of individual components in case of later wear and tear.

Depending on the application, exhaust gas lines are often operated under temperatures between 200° - 600°C. The material for the lines must be chosen based on the parameters: temperature, pressure, strength, and corrosion demands. The pipe or duct must be able to handle the linear expansions caused by these temperatures. For this, expansion joints and a combination of floating and fixed bearings are needed. Calculations for the piping network and a structural analysis are necessary for the planning and the drawings.

Industrial fans – especially centrifugal fans – create average to large volumes of air with high pressures. In order to best technically and economically dimension the pipe and duct networks, exact specifications of the operating conditions are needed: medium, amount of over- and low-pressures, temperature and tightness requirements.  The system is planned on site and factors in such things as process data, air volume, duct cross-sections and components such as filters or heat exchangers. The pipe and duct systems are designed and produced based on all of these factors.

Grains are pre-cleaned in the ducts – “the chaff is sifted from the wheat”. Typical duct cross-sections have edge lengths of 600 - 1200mm. On site several of these curved and welded duct assemblies are screwed together with other components to form a grain processing plant.

Stainless steel designs – our specialty! Cutting, laser cutting, bending, rounding, welding, blasting, pickling, grinding. We manufacture welded constructions for all applications according to customer-drawings or based on designs developed together. We make one of a kind products as well as batch productions. The surface treatment, e.g. blasting or pickling, can be done right in our own facilities, which saves money and time on our customer’s projects!
