Extraction of oil mist

During the machining of metals, the cooling lubricants produce mists and fumes. For safety and environmental reasons, these need to be extracted and cleaned. A company in the metalworking industry has installed a condensate-tight pipework system from JACOB for conveying the mists and vapours to its central filter system.

The project

When metals are machined, cooling lubricants are used in the machine tools to cool and lubricate and to remove the chips. Mist, fumes and smoke are produced in the process, and these need to be extracted and cleaned, for safety reasons and for environmental protection. The central extraction system in the company’s production halls was installed using JACOB’s longitudinally seam-welded pipework for extracting the exhaust air within the machine and for the ducts between the machine and the filter.

The implementation

A central exhaust system was installed in each of the two production halls, to serve a total of 31 CNC machines. JACOB’s modular pipework system was used to connect the machine tools to the filter system. The pipes used are 1 mm thick, powder-coated, and have diameters ranging from 100 mm to 450 mm. The individual pipe components were connected quickly and easily using JACOB’s pull-ring system and oil- and grease-resistant U-shaped seals made of NBR.

The special features

For this project, it was extremely important to ensure that no aerosols or condensates could escape from the pipework system. JACOB’s longitudinally seam-welded pipes are perfect for this, as they have no potential leakage points. The connection system is equally important, of course. Here, the individual pipe elements are connected with U-shaped seals and pull-rings, which ensure optimum tightness. Another advantage for this project was that JACOB offers U-shaped seals made of different materials. In this case, the planners opted for seals made of NBR, which is resistant to oils and greases. The JACOB system not only met the stringent sealing requirements, but also brought a high level of flexibility to the project: thanks to JACOB’s modular design and more than 8,500 standard parts, the pipework system was adapted to suit the conditions on site and can be easily expanded as needed.

JACOB dealt with the individual transitions to machines and filters by producing custom-made products. Even if machines need to be relocated later, the company can easily adapt the extraction line to meet the new requirements: the individual pipe elements can be simply detached and removed from the overall system by opening the pull-rings – without any cutting or welding that would damage the pipes. The experts carried out the preliminary design of the pipe runs using models from the JACOB CAD database. To calculate the costs, the company used the project planning tool in JACOB’s online shop. This tool can also be used to quickly reorder new parts as required.

JACOB pipe systems take less time to install than conventional systems. Using the QUICK CONNECT pull-ring makes things even faster. This saves time and money!
