Rectifiers are used in pipe and duct systems to ensure an even flow into specific fitted components, such as heat exchangers. Without an appropriately uniform inflow, these components do not reach their level of efficiency and would, therefore, not fulfil their desired function. The assembly is manufactured out of lasered sheet metal and is put together by means of tongue and groove before it is welded. This ensures the exact fit of the pieces and minimizes the distortion of the welding.

Venturi nozzles or Venturi tubes are used in pipe systems, in which the rate of air flow must be continually measured and recorded. At the same time the components and the methods used for measuring must be suitable for the demanding industrial marginal conditions and the media with which they come in contact. The diameters used for the reductions, as well as, where the measurements are taken, conform to the diameters where the tubes connect in the system and with the amount of air that needs to be measured.

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.

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.

The structural stability of intake and exhaust air towers is tested by structural analysis calculations. Depending on on-site conditions, the towers can be attached to the walls of the building with brackets for extra support. For freestanding intake and exhaust air towers anchor cages are usually used. The anchor cages, designed to be set in concrete, can be delivered prefabricated or, as in the photo here, as a double-flange construct with gusset plates, which are bolted to the existing substructure – Design and drawings “made by LBF Technik”!

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!
