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 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.

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”!

Exhaust air or wastewater flow often accumulates in industrial plants and needs to be chemically or thermally treated – as an alternative, filter systems can be used. The customer or planner decides on the most sensible process and LBF designs and constructs the corresponding vessels –stainless steel 1.4301 or 1.4571 is usually used here with a typical thickness of 3-6 mm. In particularly critical cases, an additional interior coating (e.g. rubber lining) can be applied.

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.

Cyclones are designed as centrifugal separators and, therefore, also used as filters. The construction is robust and contains no filter media (low-maintenance). The starting medium is blown in via the tangential media inlets. Solids and heavier components are guided downwards by gravity and passed through sluices or caught in dust collecting boxes.
