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!

We produce custom pipes and casings under the motto “If it can be designed, it can manufactured”. LBF produces welded constructions based on customer-drawings (STEP-, DWG-, DXF-files) or LBF drawings developed and released together with the customer. Some of these constructions require very stringent testing and documentation, e.g. for Exxon, BASF or for use in nuclear engineering.

Profile and pipe frame structures are produced as powder coated, painted or hot-dip galvanised. They are used as a base structure for noise protection casings, as engine mounts or for whole CHP facilities. As a rule, the decision of whether the structure is completed in one piece or bolted together from various pieces is based, in part, on the structural design, on the assembly conditions on-site or the required surface treatment.

The central pipe with apparatus flange is fitted with lateral nozzles placed in regular intervals along the complete length of the pipe. These are used, among other things, as measuring points and must be precisely aligned and calibrated. The pipe is assembled from multiple sections and delivered in one piece. Provided documentation includes inspection certificates of the material and test protocols for the demension inspection, weld seam evaluation ISO 5817, quality level C and surface treatment – pickling.
