Definitions

  • the flow pipe 17 can be manufactured in several different ways. One way is to manufacture it using a casting process.
  • the flow pipe 17 can then be of a material that is, for example, a plastic.
  • Polyethylene, or thermoplastic in general, can be given as an example of plastics.
  • a thermoplastic flow pipe 17 can also be welded, if the operation in question is seen to be necessary, for example when assembling a turbulence generator 14 from pipes 17.
  • a plastic flow pipe will resist water, chemicals, and washing agents.
  • Various machining methods can also be used to manufacture a flow pipe from, for example, metals or composites.
  • Yet another example of a possible manufacturing method is 3D printing, which also permits the economical manufacture of small batches.
  • Figure 6 shows an arrangement, in which the sheets 28 are installed at the end of the bank of pipes.
  • the attachment rods 30 at the inlet-end edge of the sheet 28 are in slots 31 formed by the stacked flow pipes 17, 17', thus forming a shape-closure joint.
  • the internal diameter of the slots 31 can then be, for example, 6 - 15 mm.
  • pipes 17, 17' manufactured by moulding there can be a high degree of integration, because the attachment shaping of the sheets 28 is achieved in the ends of the pipes 17, 17' already in the moulding process, so that there is no need for separate sheet grooves.
